Power Supply Standard, 640mA, MDRC

Product code: 2CDG110167R0011
Power supply with integrated choke for production and monitoring of the KNX system voltage. The power supply is connected to the bus line via a bus connecting terminal.
Price (Excluding VAT)


KNX power supplies generate and monitor the KNX system voltage (SELV). The bus line is decoupled from the power supply by an integrated choke.

The voltage output is short-circuit and overload protected. The two-colour LED indicates device output status.
