MDT - KNX Dimming Actuator 4-fold, 8SU MDRC, 250W, 230VAC

The MDT Dimming Actuator receives KNX/EIB telegrams and dimms/switches up to 4 independent electrical loads. Each output can be operated manually via a push button.

The outputs are for switching and dimming incandescent lamps, HV halogen lamps, LV halogen lamps (with conventionel or suitable electronic transformers), dimmable energy saving lamps and LED lightning. Leading or trailing edge principle can be chosen. The device has an integrated shortcircuit and excess temperature protection plus softstart function (Dimming speed adjustable) to increase lamp life time.

Programmable performance after mains voltage failure, bus voltage failure or return. The 1-10V MDT Control Device has embedded switching relays for 30 ECG/30W, 20 ECG/58W, 15 ECG/2x36W or 10ECG/2x58W. Each channel offers control voltage up to 30 electronic transformers (ECG).

The MDT Dimming Actuator is a modular installation device for fixed installation in dry rooms. It fits on DIN 35mm rails in power distribution boards or closed compact boxes.

For project design and commissioning of the MDT Dimming Actuator it is recommended to use the ETS.
