Frequency converter = - Do you have an AC motor and want to control its speed? Then the use of a frequency converter is an interesting product for you. A frequency converter is always used when you need permanent speed control on a machine. This can be, for example, pumps or compressors, but also fans, mixers or mills with electric motors. A frequency converter converts the fixed mains voltage into a variable voltage. This enables not only operation of the motor at a constant speed, but also acceleration and deceleration. In this way, the speed of a machine can be adapted to the current work requirements, energy can be saved if necessary, or production processes can be varied over time.Use the high-quality frequency converters from the eibabo® shop, protect materials with speed control and thereby extend the service life of your machines. Manufacturers of high quality goods are ABB, Eaton, KEB Automation, Maico, Mitsubishi, Omron, Rockwell, Schneider Electric and Siemens.What is electrical frequency?In order to explain electrical frequency and to be able to deduce the function of a frequency converter, we must first look at the basics of electricity generation. There is direct current and alternating current. Direct current always flows in one direction. Alternating current periodically changes direction. This change is represented in a diagram in the form of a sine wave, which is alternately in the positive and negative area of the zero point. Accordingly, an alternating voltage is also an oscillating electrical voltage.Already knew?The Danish company Danfoss was the first company to start series production of frequency converters. This was in 1968.The AC frequency describes the number of cycles in this sine wave per second and corresponds to the number of changes in direction. This is given in Hertz (Hz). 1 Hertz corresponds to a complete cycle from the zero point to the positive range, to the negative range and back to the zero point. The more cycles per second occur, the higher the frequency. The usual mains electricity in Germany and Europe has a fixed frequency of 50 Hertz.How does a frequency converter cause a change in motor speed?The standard speed of an AC motor is tuned to a specific frequency. This is based on the structure of the respective motor. A constant magnetic field with stationary poles prevails between two field magnets. Within this magnetic field is a rotating, also magnetic 'anchor' with two poles. If alternating current is passed through the armature, its polarization changes in time with the alternating current. With a mains frequency of 50 Hz, this happens 50 times per second. Accordingly, the attractive and repulsive forces between the field magnet and the armature change direction 50 times. Once set in motion, this alternation ensures a certain rotational movement of the armature and speed of the motor. Each change in frequency therefore also causes a proportional change in motor speed. The frequency converter is responsible for changing the frequency.The advantages are:infinitely variable control of the desired nominal speedReach very high and very low speedsdirect switching of the direction of rotation Picture: Schneider Electric ATV320U22N4C frequency converterWhat are the reasons for a change in engine speed?An almost constant frequency is applied to the classic AC network and therefore only one speed is available to you. The frequency converter regulates the frequency and voltage of the power supplied to the motor. That is why this device is often also called a speed controller. There are many reasons why the engine speed needs to be adjusted:to save energy and increase efficiencyto optimize the flow of manufacturing processesto protect material and extend the service life of machinesto meet the requirements of processing various materialsto adjust the torque / power of a driveto lower the noise levelto reduce peak loads Modern frequency converters have network and diagnostic functions. This makes it possible to integrate the devices into the control system of a plant and to monitor and optimize all processes.Where are frequency converters used?Frequency converters are used in numerous industries and applications. These devices are mainly found in compressor, pump and fan drives. But the speed of conveyor belts, production lines or cranes can also be controlled with frequency converters. An adapted or infinitely variable speed enables energy-efficient and optimized production processes.What should be considered when buying a frequency converter?The correct selection of the frequency converter is crucial for the optimal operation of the corresponding devices. Before selecting the drive, determine the number of input phases. Will the device be three phase or single phase? Will the device handle resistive loads, inductive loads, capacitive loads, or mixed loads? The individual loads cause different inrush currents when starting. Please consider this. Before you buy, find out about:the requirements of the operating environmentthe starting torquethe load torque characteristicsthe speed control range and the static speed accuracy TIP:You are very flexible with regard to the location. Frequency converters are available for installation in the control cabinet, for wall mounting and for decentralized field use. Since a certain level of expertise is required to evaluate these properties, we recommend consulting an experienced electrician.

Socket - A socket is much more than an inconspicuous power supply on the wall. Find out here which sockets are available and why you can never have enough of them. In addition to buttons and switches, sockets are among the most important products of all manufacturers of switch programs. A socket is installed either permanently on a wall (surface-mounted socket) or recessed (flush-mounted socket). Sockets can also be part of a mobile line coupling, such as table or multiple sockets. There are also sockets on extensions that are intended for mobile use. A socket is mostly used for the power supply. There are also sockets for telephone / telecommunications and for the data transmission sockets. Devices are usually supplied with single-phase alternating current (in Europe 230 volts) or three-phase alternating current (three-phase current with 400 volts) via classic sockets. There are also standardized sockets for 12V direct current. There are separate socket systems for the supply of higher voltages and currents.Basic information about sockets - in a nutshellA distinction is made between the flush-mounting and surface-mounting types. With the flush-mounted variant, sockets are mounted in switch boxes, which in turn are embedded in the wall. In the 'surface-mounted' variant, sockets are attached to existing walls, usually with dowels and screws.Double sockets are usually nothing more than two single sockets. They obtain the energy from the same supply line. Flush-mounted variants can be optically connected to one another via the frames of the switch range. With surface-mounted devices, both sockets are supplied in one housing.A socket insert is a device for installation in the switch box. It is either attached using claws (clamp connection) or by screwing the base plate of the insert to the screw holes of the switch box. The insert must be supplemented by the frame of the switch range.High-quality moisture-proof sockets usually have a self-closing cover and a rubber seal around the base. They are used in bathrooms, kitchens or utility rooms.Outdoor sockets must protect the current-carrying cables from rain and snow. Their housings are often particularly stable in order to prevent damage from mechanical influences.The degree of protection is a determining variable for the place of use. The best known is the two-digit IP protection class (IP = International Protection / Ingress Protection). The first digit stands for protection against contact and foreign bodies, the second digit for protection against water. The higher both digits, the safer. Planning of sockets - there is no such thing as too muchIf I were to build a house again, I would do many things differently.' You hear it very often like this or something similar when you talk to builders. Not infrequently, the planning and implementation of the electrical installation is one of the things that could be better. It is often the insufficient number of sockets that makes everyday life unnecessarily cumbersome. For example, if there is no socket in a dark corner of the room, you must lay an extension cord for the lamp. You probably won't connect very many electronic devices in a bathroom. A living room is usually equipped with many devices and is occasionally rearranged. Many sockets offer flexibility here. TIP:Sockets are very cheap to buy compared to the whole building. Do not plan too tightly, but generously. But positioning also plays an important role. Plan ahead with the layout of your home, the furnishings, and the purpose of the room. Think about the different uses throughout the year. For example, the following are often overlooked:Sockets in the window reveal to supply the Christmas lightsSockets at ceiling height for extractor hoods, infrared heaters and the likeSockets in the attic (for later expansion)the right sockets in hobby rooms, if necessary for devices that require three-phase currentOutside sockets on the balcony or terraceOutdoor sockets near a cistern or water barrel to feed a pumpOutside sockets in the carport or near storage areas for wood and the likeOutside sockets on the property line / driveway The Schuko sockets in the eibabo® online shopThere are many types of sockets. The so-called Schuko socket is the standard in Europe. The abbreviation SchuKo stands for 'protective contact' and is a designation for the German-speaking area. Internationally, these devices are referred to as type F sockets. Cables with three cores are connected to sockets of this design, one of which serves as a protective contact. This derives leakage currents. The matching plugs (e.g. on electrical devices) are also constructed according to this principle. In this catalogue, we present you with high-quality sockets from over 30 manufacturers, including Gira, Jung, Merten, Hager, Berker, Legrand BTicino, Busch-Jaeger and Siemens.How much load can a single socket withstand?A classic 230 volt household circuit is usually protected with 16 ampere fuses. This results in a maximum load capacity of the circuit of 3680 watts (16 amps x 230 volts). This means that you could theoretically draw 3,600 watts of power from a standard household socket. NoticeWhen it comes to electrical installation, it is advisable never to push individual devices to their capacity limits. In practice, about 2500 watts should not be exceeded at a socket. Based on Central European standards, 200 watts to 300 watts per individual socket is assumed in everyday use. With double sockets it is up to 500 watts. You should take this guideline into account when planning the maximum number of outlets per circuit for your installation.Does eibabo® also offer sockets of other standards?eibabo® is an international online mail order company and offers sockets that are common outside of Europe. The best-known form is the NEMA standard, which is not used in Europe (with a few exceptions). NEMA stands for National Electrical Manufacturers Association and describes a whole range of different sockets and power plugs. These are commonplace in America, such as the United States, Mexico, and Canada. Type B (NEMA-5-15) single-phase AC power is most commonly used in the United States. The regular operating voltage is 120 V, the mains frequency is 60 Hz. NEMA-6 series connectors are intended for heavy loads such as electric ovens. The NEMA system is also in use in parts of Asia, including Japan and Thailand, China and the Philippines. In addition, at eibabo® you will find sockets according to British Standard, Swiss Standard or Australian Standard.How do I integrate a standard Schuko socket into the smart home?An existing socket can be easily expanded in terms of functionality using a WLAN socket. As a rule, these are adapter plugs that you plug into the existing socket. These represent a link between the end device and the socket. An associated application (software) enables the connection to the home network. But it doesn't have to be WiFi. Other models use Zigbee, Z-Wave and Bluetooth as radio technology. If your electrical installation is just being planned, we recommend reserving a few sockets for your smart home. Then you have the option of using the corresponding flush-mounted sockets. These look visually appealing like classic sockets. You no longer need an additional adapter plug.Already knew?At the beginning of the electricity age, sockets and light switches were considered status symbols. Those who were self-respecting presented the electrical installation of the house 'surface-mounted' and clearly visible to everyone.The advantages of such sockets are, on the one hand, that the devices connected to the sockets can be disconnected from the power supply quickly and easily via the smart home system. In this way, the devices do not run on standby and save electricity. On the other hand, you can operate the sockets when you are not at home. If such a device is compatible with Apple HomeKit, Google Assistant or Amazon's Alexa, you can use it to control it.What is the difference to a socket with increased contact protection?At first glance, a socket with increased contact protection can hardly be distinguished from a classic socket. Some manufacturers mark such a model with a small symbol on the case.Image: Gira 045327 Schuko socket outlet with child protectionSockets with increased contact protection have an additional internal safety device that can vary depending on the manufacturer. In some models, this consists of rotary vanes. These open when both pins of a connector exert pressure on them at the same time. With other systems, the central insert can be rotated. So no object can be inserted into the holes of the socket. The installation of such sockets is recommended, for example, where children may have access to them. In other wordsThe designation 'Schuko' for protective contact has nothing to do with protection against accidental contact. Protection against accidental contact must also be provided. An alternative to the socket with increased protection against accidental contact can be separate socket protection. These plug into a standard socket and often work with a twist or slide motion as well. It is very safe with socket locks or lockable flaps.Why should I lock an outlet?Sockets are everywhere. These cannot always be monitored. In times of constantly rising energy costs, one often hears about electricity being stolen unnoticed via a hidden socket. This is made particularly easy for thieves if the socket is publicly accessible. Even if animals, children or other vulnerable people are constantly in the immediate vicinity of the socket, we recommend a lock. Lockable sockets or socket locks are available in the eibabo® shop at reasonable prices. Use our intelligent search.Are there sockets for other areas of application?In addition to classic sockets for everyday use, there are sockets in special shapes. You may need sockets in a place where neither a flush-mounted socket nor a surface-mounted socket is possible. A classic example is the junction box. Here you need a socket with mounting options on the DIN rail. Such models are often adapted in width to the pitch units in the junction box. Another special form are the so-called CEE sockets. These are available in the strengths 16 A, 32 A, 63 A and 125 A and are equipped with three to seven pins. Different colors represent the appropriate nominal voltage. The eibabo® shop offers CEE sockets and sockets for the junction box in separate catalogues.

Pendant lights - Find the right pendant light or hanging light at eibabo®. Our extensive lighting catalog leaves nothing to be desired. Read on to learn about the different styles, colors, materials and sizes. In addition, you will receive conventional light sources or economical LEDs to match.Where are pendant lights used?When we think of pendant lights, the place above the dining table comes to mind as a classic place of use. And indeed, pendant lights are often mounted above tables such as the dining table or coffee table and, as ceiling lighting, create atmospheric light when eating or socializing. But pendant lights are also decorative alternatives in other places. Think of a counter in a bar, the reception area of the doctor's office or the reception desk in a hotel. With a bit of creativity and stylistic sensitivity, you can turn pendant lights into full-fledged furnishings that create atmosphere and enhance your ambience. Pendant lights are even used in industrial workshops. However, these are technically and optically optimized for these applications.Image: Fischer & Honsel 69540 LED pendant lightWhat should be considered when installing pendant lights?Remember that pendant lamps need a reference point in order to look their best. Suspended anywhere in the room, pendant lights usually look out of place. Pendant lights can be ideally adapted to the spatial conditions. With high ceilings, the length of the suspension can often be adjusted manually. A distance of around 60 to 80 cm above the edge of the table has proven to be the ideal height for lights above the dining table. Of course, this can vary depending on taste and the size of the lamp. You should make sure that your new pendant lamp has a lampshade in order to form a cone of light and direct the brightness optimally to the desired area. As a result, other areas are not or only diffusely illuminated and the light is not perceived as disturbing.our recommendationAvoid pendant lights in rooms with low ceilings and bathrooms. Use ceiling spotlights or recessed spotlights instead. For cheap and stylish spotlights and recessed lights, please select the appropriate category here in the shop.Smaller pendant lights with a small lampshade look particularly stylish when placed above bedside tables, your bar or a side table. Many of our pendant lights are also available in versions with multiple light sources, so that you can easily implement uniform illumination of larger tables or longer areas.How big should a pendant light be?For a successful look, it is advisable to follow a few basic stylistic rules, especially in the private sphere. These relate to:the size/diameter or circumference of the pendant light in relation to the room sizethe installation height in relation to the room height It is assumed that lamps that are too large or too small disturb the harmonious overall impression. Calculating the rough guideline is quite simple:(Length of the room in meters + width of the room in meters) x 10 = the optimal diameter of the pendant light in centimetresIt is clear that very few lights consist of a sphere and therefore the diameter cannot always be used as a reference. Alternatively, the circumference calculated from this can be used, for example if the pendant light consists of several spheres or has an elongated shape. An example:(Room length 5.5 meters + room width 4.5 meters) x 10 = 100 centimeters in diameter or 314 centimeters in circumferenceOf course you can also deviate from this. Other influencing factors often also play a role in the decision. For example, whether the floor plan of the room is very simple or complex, or whether there is already a lot of furniture in the room. The height of the pendant lamp should not be more than one third of the distance from the floor to the ceiling. With a ceiling height of 3 meters, this is 1 meter. For classic living room heights of around 2.7 meters, 50 to 70 cm should be chosen so that the height to the floor is at least 2 meters.Are pendant lights also suitable as workplace lighting?The lighting effect of pendant lights results from the design, the light source used and the positioning of the light. In this way, you can influence whether the effect of the lighting should be more direct or more indirect, or whether the light should be diffused or directed. You can also use pendant lights in the company as office lighting or workplace lighting. Of course, the requirements for optimal lighting in the workplace are high, but with the right shape and suitable lamps, this can be implemented without any problems. TIP:If necessary, such pendant lights for the office can be equipped with a grid or diffuser in front of the light source. These emit a glare-free light on the work area. Use pendant lights in an elongated design if they are to be placed directly above the desk. LED strips ensure even light distribution over the entire length. This ensures that the pendant lights used do not cast any lateral shadows and that the entire work area is optimally illuminated. The higher the light source, the wider the irradiated area and the lower the illuminance on the floor and work surface. To ensure the desired light intensity, you should adjust the height of your pendant lights correctly. Never place them lower than two meters so that employees do not accidentally hit their heads.What advantages do pendant lights offer?The main advantage of pendant lamps is the ability to place light sources at the right height. This is especially useful when organizing lighting on dining tables, kitchen worktops, warehouses, machine rooms, workshops and industrial halls where the rooms typically have high ceilings. Another plus is the easy installation. How a pendant light is attached depends on its design. Usually 1 to 2 suspension points are required. Particularly large and heavy models can also have more suspension points. Whether for private use or commercial use - pendant lights are available in countless variants, colours, price ranges and designs. There are both classic and creative pendant lights of various types on the market. The selection is so large that you are sure to find a model that suits you.Which bulbs should I use for pendant lights?When buying your new pendant light, don't just look at its appearance. Consider at the same time an economical, effective and powerful lighting effect. This is easily possible with LED pendant lights. Pendant lights with LED bulbs offer lower power consumption and a long service life. The LEDs are often permanently installed and cannot be replaced individually. But the use of energy-saving lamps is also recommended for pendant lights with replaceable lamps and classic screw sockets. Be sure to pay attention to the color temperature emitted by a light source. This is given in Kelvin (K). The higher the value, the more the color temperature shifts towards the blue. Daylight of around 5,500 Kelvin is recommended for use in laboratories, classrooms or in industry. This increases concentration and prevents fatigue. The somewhat warmer neutral white is generally used for offices. For comparisonCandlelight has a color temperature of around 1500 Kelvin. Lamps with a color temperature between 2200 and 2700 Kelvin are the right choice for a cozy atmosphere at the dining table.By the way:The chandelier is considered the forerunner of the modern pendant lamp. This was typically a multi-level lamp made of copper or iron, which was hung on chains and sometimes equipped with numerous candles. Magnificent accessories made of glass and crystal reflected the candlelight and thus optimized the light output.
