KNX power supply 1280mA with integrated throttle and diagnostic function KNX-40E-1280D

The Mean Well EIB/KNX power supply KNX-40E-1280 D is a 1280mA power supply with high efficiency and a small footprint of only 4SU (72mm). The device has a KNX bus choke output and an additional output for auxiliary power. The -30°C to 70°C wide temperature operating range can meet all kinds of applications. For troubleshooting, monitoring purpose, output voltage, output current, bus traffic, device temperature and other actual measurement values can be sent via KNX. LED indicators are used in case of normal operation, overload conditions and reset-operation. It is perfectly suitable to power up any products labeled with the KNX trademark. With over 30 years of industrial power supply experience, KNX-40E-1280 D is engineered to be a reliable and safe solution for the KNX bus environment.
