Product Manual
1 Overview
The EIB / KNX bus power supply is used to provide and monitor the voltage of the EIB / KNX system. The output has
two terminals, including one KNX bus output for EIB bus power supply and signal transmission. One 30V DC auxiliary
output and provides a power supply voltage of 30V DC, 640mA which can be sent to the terminal; the reactor has been
integrated into the bus connection terminal; if a reactor is connected to the 30V DC auxiliary power supply terminal, it
can also be used as a bus power supply terminal and also has a signal transmission function.
In order to facilitate installation into the distribution box, the KNX bus power supply is designed as a modular
installation device that can be mounted on a 35 mm DIN rail. The equipment adopts screw terminals to realize 220V
voltage input and auxiliary power output connection. The EIB bus connection is directly connected through the EIB
terminal (red / black).
The power can be reset by pressing the reset button on the device for 24s.
Functions:
（1）Meet the power supply of KNX / EIB bus equipment；
（2）LED1（ON）Green indicates normal operation，LED2(Reset)Red indicates reset，LED3(I>Imax)Red indicates output
overcurrent, short circuit;
（3）With output short circuit, over current, over voltage protection function;
