Capacity enhancer for universal dimmer switches. Power MOSFET up to 400W. Standby loss 0.1 watt only. Modular device for DIN EN 60715 TH35 rail mounting. 1 module = 18mm wide, 58mm deep. Capacity enhancers LUD12-230V can be connected to the universal dimmer switches EUD12D, SUD12 (1-10V input) and the multifunction time relay MFZ12PMD. By this the switching capacity for one lamp will be increased up to 200W or alternatively for additional lamps up to 400W per each capacity enhancer. Dimmable 230V LED lamps and dimmable energy saving lamps are also dependent on the lamp electronics. Both switching modes for increase of capacity can be executed simultaneously. Automatic lamp detection in the Capacity increase with additional lamps setting. Supply voltage 230V. Automatic electronic overload protection and over-temperature switch-off. In the mode Increase of capacity with additional lamps the kind of load of a capacity enhancer LUD12-230V can vary from the kind of load of the universal impulse dimmer switch. Therefore it is possible to mix L loads and C loads.
