Dimmer Module
DFDM dimmer modules allow the driving, through the Domino bus, of 1 resistive or inductive load up to 300W, such as incandescent or halogen lamps and transformers for low voltage lamps. DFDM module operates the phase control of the 230Vac mains supply by a TRIAC power device.
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). For installation inside wall boxes.
Notes:
DFDT module cannot drive fluorescent lamps.
Load with power factor correction capacitor must be avoided.
DFDT module contains a phase-controlled device (TRIAC). A built-in EMC noise suppression filter may generate a light buzzing that may be heard in very silent rooms; this, however, does not affect the proper operation of the device.
(*) For LED or ESL lamps, proper operation strictly depends on the type of lamp used; the proper operation cannot be guaranteed in advance for this type of lamps, even if they are declared “dimmable” by the
manufacturer.
