KNX
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-color LED indicates device
output status.
This device 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).
