K-BUS Power Supply User manual-Ver. 1
EIB/KNX power supply produces and monitors EIB / KNX system voltage. The bus line is decoupled
from the power supply with the integrated choke.
The power supply is connected to the bus line with a bus connection terminal. A reset is triggered by
pressing the reset push button and lasts 22 seconds (regardless of the duration of the push button
action).The bus line disconnected from the power supply and the devices connected to this bus line are
returned to their initial state. If the line should be disconnected for a longer period, the bus connection
terminal must be removed from power supply.
A 30V DC auxiliary voltage is made available via an additional connection terminal. This voltage can
be used to supply a further bus line (in connection with a separate choke).
