The rotary dimmer switches and dims light sources such as light bulbs, HV halogen lamps, LV halogen lamps with Gira Tronic transformers or LV halogen lamps with conventional transformers. Auxiliary unit operation is possible using an auxiliary unit insert. The dimmer can be operated together with a mains decoupler.
A mains decoupler cannot be operated when auxiliary units are connected. Capacitive loads (e.g. Gira Tronic transformers) and inductive loads (e.g. conventional transformers) cannot be connected to the universal dimming insert at the same time.
