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 (MP6402) / 500mA (MP6401) 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).

MP6401

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）The yellow-green status LED indicates the current auxiliary power supply status. When the auxiliary output status LED is constantly on, it indicates that the auxiliary power supply is normal. When the status LED flashes, it indicates that any of the auxiliary power supply is overloaded.

（3）The red LED is always on to indicate that the KNX bus output exceeds the rated current of 640mA. When the KNX bus output current exceeds 900mA, the bus output is automatically cut off and the red LED flashes. Press the reset button to restore.

MP6402

The power can be reset by pressing the reset button on the device for 20s.

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;
