Use

The universal dimmer is a 4 MU-wide device for DIN-rail mounting with N-system dimensions.

It is designed for lighting control, i.e. for switching and dimming resistive, inductive or capaci-

tive loads ranging up to 300 VA with 230V AC, 50/60 Hz per output. The bus is connected via a

bus terminal block. The device electronics are supplied via the bus voltage.

Application

The device can be connected with loads on two outputs or for a higher load only with one

output. A minimum load is not required.

Fig. 1 shows a 2-channel application with two independent controlled outputs.

Optional a 1-channel application uses only one output A or B with higher load.

Note: Neutral (N) is not connected internally. External connection is needed for each channel.
