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 circuit KNX bus output for EIB bus power supply and signal transmission, and one circuit 30VDC auxiliary output, which can provide a 30V DC power supply voltage to the terminal device. The bus connection end has integrated a reactor inside the power supply. If a reactor is connected to the 30VDC auxiliary power supply end, it can also be used as a bus power supply end and has signal transmission function.

In order to facilitate installation in the distribution box, the KNX bus power supply is designed as a modular installation device that can be installed on a 35mm DIN rail. The device uses screw terminals to realize 220VAC voltage input and auxiliary power output connection. The EIB bus connection is directly connected through the EIB terminal (red/black).

The power supply can be reset by pressing the reset button on the device. During the reset, the bus power supply end of the power supply is powered off, and other devices connected to the bus return to their initial state.
