Product Description

The MD0403.432 supports leading edge TRIAC dimming, and has four selectable dimming curves. Both inductive and resistive loads can be controlled, as can capacitive loads like LED drivers, and electronic ballasts which use leading edge TRIAC dimming. Immediate controlling is possible via four on-board manual buttons.

Different load Types

Both inductive loads and resistive loads are supported; this means incandescent bulbs and motors can work simultaneously. Some capacitive loads can work in combination with the constant current module. Energy saving lamps, and non-dimmable lamps are not supported however. The minimum system load is 40w.

Selectable Dimming Curves

With 4 different dimming curves, and a dimming accuracy of 512 steps, the dimming actuator operates smoothly giving total control to the end user.


The system uses replaceable fuses to protect against the short circuiting of loads, and accidental over load. LED status indicators are also able to pinpoint where any short circuits occur, this facilitates swift repairs and easy maintenance.


To prevent damage to the system and module a variety of protective features are included. With an over heat sink, electronic short circuit protection, internal overheat protection, and overload protection, safety is guaranteed.

Scene Recovery

When the dimmer has been powered off, it is able to automatically restore the last scene used when powered on again. This gives the user a system that remembers their previous scene, and requires no further control.

Manual Control

With the ability to bypass the main control interface, and manually control each channel, this unit gives an end user the ability to switch the dimming controller on & off.
