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.
Device type SV/S 30.640.5.1 has an additional 30V DC short-circuit and overload protected voltage output that can be used to power an additional bus line (in combination with a separate choke).
