12 2CDC501049D0201 Rev. A | SV/S xx.xxx.x.1
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).
