Power booster for universal dimmer switch. Power MOSFET up to 400W. Standby loss only 0.1 watts. Modular device for mounting on DIN-EN 60715 TH35 rail. 1 division unit = 18mm wide, 58mm deep. LUD12-230V power boosters can be connected to the universal dimmer switches EUD12D, SUD12 (1-10V input) and to the multifunction time relay MFZ12PMD, which increases the switching capacity for one light by up to 200W, and for additional lights by up to 400W per power booster, depending on the ventilation conditions. Dimmable 230V LED lamps and dimmable energy-saving lamps also depend on the lamp electronics. The two circuits for the power increase can be carried out simultaneously. Automatic lamp detection in the power increase circuit with additional lights. Supply voltage 230V. Automatic electronic overload protection and overtemperature shutdown. The load type of a LUD12-230V power booster can differ from the load type of the universal dimmer switch in the power increase circuit with additional lights. This makes it possible to mix L loads and C loads.
