The FD3 U2 electronic universal pushbutton dimmer, with an extremely compact box installation housing, can dim virtually any type of lamp (LED, CFL, incandescent, LV halogen with electronic or wound transformer, HV halogen) that is suitable for forward or reverse phase control.
The correct dimming mode can be detected automatically, or it can be set manually to forward or reverse phase control. A special CFL dimming mode additionally provides an ignition and warm-up delay for compact fluorescent lamps (“energysaving lamps”).

The button input and the functions of the wireless transmitter buttons are individually programmable. This makes both individual control and group control possible in a very flexible manner (one or two button control, on/off switching with/without dimming function, etc.). In addition, brightness memory, slumber function or soft on/off function can be specified.

The compact dimensions of the FD3 U2 allow it be installed in electrical boxes behind a button switch from any desired product line, making it equally suitable for new installations as well as for maintenance-free replacement of existing or defective rotary or button dimmers.

Also available as a simple version (without special programming functions): FD3 U2E
