Dimmer Module IGBT
DFDI dimmer module allow the brightness regulation of lamps up to 300W.
DFDI module operates the phase control of the 230Vac mains supply by an IGBT power transistor; thanks to this technique, DFDI module can be set for two operating modes:
• reversed phase control (“trailing edge”): for resistive or capacitive loads such as electronic transformers and incandescent lamps
• direct phase control (“leading edge”): for inductive loads such as ferromagnetic or toroidal transformers
The module can be controlled by pushbuttons connected to Domino input modules or by a supervisor or by a video-terminal (e.g. touch screen).
Notes:
DFDI and DFDI2 modules cannot drive fluorescent lamps.
(*) For LED or ESL lamps, the operation closely depends on the exact type of used lamp;
it is not possible to guarantee in advance the proper operation with this kind of lamps, even if they are declared as dimmable.
