Scope of application: LED dimmer ing to UKCA and CE standards. For switching and controlling incandescent lamps, dimmable LED lamps, high-voltage halogen lamps, and halogen lamps with electronic transformers. Not suitable for controlling transformers, fans, or inductive motors. Specifications: Rated voltage/frequency: 220–240 VAC/50 Hz. Adjustable power: 3–100 W. Dimmable LEDs (PF = Power Factor: PF > 0.9 at 3–100 W, PF > 0.5 at 3–50 W). Dimensions (mm): 81 x 33.4 x 22 x 34.8. Single wire connection: 0.75–2.5 mm. Color: White. Easy to use: The LED controller allows dimming adjustment via a rotary knob to set desired lighting levels. Turn the knob clockwise to increase brightness to maximum. Turn counterclockwise to decrease brightness. Safety protection: Features electronic overheating protection. Automatically turns off when temperature reaches 80°C and resumes operation when temperature drops below 80°C. Note: Compatible only with dimmable LED lamps to prevent flickering. LED lamps must be at least 3W and compatible with trailing-edge dimmers. If the minimum or maximum brightness setting does not correspond to actual light output and screw adjustment is ineffective, the luminaire may have a limited dimming range.
