With the radio-enabled DuoFern DIN rail universal dimmer, dimmable 230V lamps can be switched or dimmed. The universal dimmer is suitable for incandescent lamps/HV halogen lamps, electronic transformers for halogen or LED lamps and for retrofit HV LEDs. Its automatic load type detection detects the connected load type or the appropriate dimming principle. Alternatively, the load type (R, L, C) can also be selected manually. The minimum/maximum brightness can therefore be manually adjusted to each lamp. In conjunction with the HomePilot, it has numerous automatic functions such as the staircase function and can be controlled via an app. Buttons can be connected for manual operation on site. Its design enables standard DIN rail/top hat rail mounting on a mounting rail (T35) and has a mounting width of 1 division unit.
