Power supply with diagnostics, 640mA, MDRC.

KNX power supplies generate and monitor the KNX system voltage (SELV). The bus line is decoupled from the power supply by an integrated choke. Bus current, bus voltage, overload and other messages can be sent via KNX for monitoring and diagnostic purposes. The voltage output is short-circuit and overload protected. The LEDs indicate the bus current consumption and the status of the line or device. Device type SV/S 30.640.5.1 has an additional 30 V DC short-circuit and overload protected voltage output that can be used to power an additional bus line (in combination with a separate choke).
