Details
Meanwell KNX-20E-640 is a 640mA power supply with high efficiency and a small footprint of only 3SU (52.5 mm). At the same time, the device has a KNX bus choke output and an additional output or ancillary power. The -30~+70℃ wide temperature operating range can meet all kinds of applications. 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-20E-640 is engineered to be a reliable and safe solution for KNX bus environment.
