AC/DC power supply EK-AB1-TP

DIN railregulatedsingle-output

Description
The Ekinex® EK-AB1-TP is a 640 mA KNX bus power supply that provides and monitors the 30 Vdc bus voltage required for KNX operation. An integrated choke decouples the power supply from the bus line. On a bus line powered by a 640 mA unit, up to 64 KNX devices can be connected. The output is protected against overload and short-circuit, ensuring stable operation for building automation installations.
