Details

Meanwell KNX-40E-1280 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 additional output for auxiliary power. At the same time, the -30~+70℃ 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. lt is perfectly suitable to powerup any products labeled with the KNX trademark. Meanwell KNX-40E-1280 is engineered to be a reliable and safe solution for KNX bus environment.
