Interra ITR900-0164 Interra KNX Power Supply 640 mA Aux. Voltage 30V DC

The Interra ITR900-0164 generates and monitors the SELV bus voltage for KNX devices connected to the bus, delivering a 640 mA busload through an integrated choke that decouples the bus line from the power supply. A wide-range mains input (85...265 V AC, 50/60 Hz) makes it suitable for worldwide use.

The unit provides a 30V DC auxiliary output, and its voltage output is short-circuit and overload protected. A two-colour LED (green/red) shows the device's output status at a glance, with maximum power consumption of 55 W and a typical draw of 24 W.
