The electronic radio universal touch dimmer FD3 U2 in the extremely compact box installation housing can be used to dim almost all lamps (LED, energy-saving, incandescent lamps, low-voltage halogen lamps with Tronic or wound transformers, high-voltage halogen lamps) that are suitable for leading or trailing edge control. The correct dimming type can be detected automatically or manually set to leading or trailing edge. A special ESL dimming type also creates an ignition and warm-up phase for compact fluorescent lamps ('energy-saving lamps'). The button input and the radio functions can be individually programmed (7 switching and dimming functions). This makes individual control as well as group control very flexible (one or two-button control, switching on/off with/without dimming function, etc.). The activation of brightness memory, snooze and soft on/off function, and the adjustment of the minimum brightness are done directly via the adjusters. Also available as a simple version without special programming functions (FD3 U2E), Compatible products: Radio transmitter FS3 series, Repeater FV2 R., Dimensions: 43x43x18.5mm, 230V AC
