Busch dimmer, gray, Busch dimmer, REG conventional dimmer, Busch dimmer REG, LED, 20-800 W touch dimmer with local operation. Optimized for dimming retrofit LED lamps (LEDi). For dimmable retrofit LED lamps (LEDi). For dimmable retrofit LED lamps (LEDi) on conventional or electronic transformers. For incandescent lamps, 230 V halogen lamps, low-voltage halogen lamps with conventional or electronic transformers and dimmable halogen energy-saving lamps. Mixed load operation with LEDi and conventional lamps possible. With memory, snooze, wake-up, children's room, central off, cleaning light and time functions. For stair light controls with automatic switch-off and warning function in accordance with DIN 18015-2. Supports compliance with the Energy Saving Ordinance (EnEV 2014). Low noise through the use of MOSFET transistors. Short-circuit proof and overload proof (electronic fuse). With manually adjustable operating mode: leading edge / trailing edge. With adjustable minimum / maximum brightness. With light value storage. Operation also possible via conventional buttons (2020 US, 2021/6 UK). Extension input for short switching pulses (button) and permanent contact (switch/timer). Extension input designed as a wide voltage input (8-230 V, AC/DC), galvanically isolated.
