LED dimmer with rotary actuator. Very low installation depth: less than 20 mm. Pressure sequence changeover switch and soft latch. 2/3 conductor connection technology (neutral conductor not required). Neutral conductor can be connected optionally (recommended when connecting low loads, less than 10 W/VA). Optimized for dimming retrofit LED light sources. For dimmable retrofit LED light sources and dimmable retrofit LED lamps on conventional or electronic transformers. Suitable for incandescent lamps, 230 V tungsten halogen lamps, low-voltage halogen lamps with conventional or electronic transformers, and dimmable halogen energy-saving lamps. Mixed load operation of LED and conventional lamps is possible. Features manually adjustable operating mode: leading edge/trailing edge phase control. Includes adjustable minimum and maximum brightness. Low-noise operation thanks to the use of MOSFET transistors. Short-circuit-proof and overload-proof (electronic fuse). Rated voltage: 230 V, plus 10% / minus 10%. Rated frequency: 50 Hz/60 Hz. Rated power L: 2 - 100 W (leading edge phase control). Rated power R,C: 10-360 W (trailing edge phase control). Rated power LED: 2-100 W (leading edge phase control), 2-200 W (trailing edge phase control). Can be illuminated by glow lamp. Glow lamp included. For conventional transformers, allow for approximately 20% transformer losses. For electronic transformers, allow for approximately 5% transformer losses.
