The brightness of lights can be conveniently controlled with the Gira System 2000 Uni LED dimming insert – for individual lighting moods and reduced energy consumption. This dimming insert can be used universally, because it calibrates itself to all common types of light source: dimmable HV-LED and CFLi lamps (compact fluorescent lamps), light bulbs and HV halogen lamps as well as LV halogen lamps and LED lamps with inductive transformers, and LV halogen lamps with Tronic transformers. If necessary the trailing or leading edge operating modes can be selected manually. An LED indicates the current operating mode. For use as a touch dimmer, a switching/dimming top unit from the Gira System 2000 is required. Top units for automatic light control can also be used – for example constant light control can be easily realised by combining the dimming insert with the Gira presence detector Komfort top unit. The universal LED dimming insert features both electronic short-circuit protection and electronic excess-temperature protection. To operate the dimmer from various points in the room, mechanical buttons or Gira auxiliary inserts can be connected as auxiliary units.
