Mean Well has been manufacturing industrial power supplies for over thirty years, and the KNX-20E-640 is engineered to provide a reliable and safe solution for the KNX bus environment.  With 86% conversion efficiency in a compact footprint, the EIB/KNX power supply is only 3SU (52.5mm) wide, has an integrated KNX bus choke output and an additional output for ancillary power. 

With a wide temperature operating range of -30 ºC to +70 ºC, it is suitable for use in multiple applications, including intelligent home control, building automation, lighting control, HVAC systems, security systems, automatic blinds and shutters, monitoring systems, energy management, and alarm monitoring.

Additional features include safety extra low voltage (SELV) and 180VAC – 264VAC input. Short circuit/overload (short-circuit proof)/over voltage protection is built in, with LED indicators clearing showing if the device is operating normally or in overload conditions or in bus reset mode. No load power consumption is <0.5W and the device meets IEC isolation protection class I and cooling is by free air circulation so that it can be installed on a TS-35/7.5 or 15 DIN rail.

In stock now at TTI, this reliable and safe power supply has been subjected to 100% full load burn-in testing and has a 3-year warranty.
