1. Introduction
2. Technical Parameter
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).
Power supply: Input voltage: 95V ~255 Vac，47~63Hz
Power loss: <6 W
Efficiency: 75%
Output: EIB/KNX output (DPSU): 1 line with integrated choke
EIB/KNX nominal voltage: 30 V DC +1/–2 V, SELV
Auxiliary voltage output: 1 (without choke)
Auxiliary voltage: 30 V DC +1/–1 V, SELV
EIB/KNX nominal current:
(Total of EIB/KNX and auxiliary voltage output) 640 mA, short-circuit-proof
Sustained short-circuit current: < 1.3 A
Mains failure back-up time: >200ms
Operating/Display:
Green LED “ON”: output voltage is OK;
Red LED “I>I
Reset push button: reset at the EIB / KNX output (starts when the push button is
Red LED: Reset at the EIB/KNX output.
Connection: power supply: 2-srew terminals
Cable cross-section: single-core 0.2—4.0mm
”: overload or short circuit
max
pressed and lasts 22 seconds);
Multi-core 0.2—2.5mm
