Scope of application: LED dimmer according 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 control of transformers, fans, or inductive motors. Specifications: Rated voltage/frequency: 220–240 VAC/50 Hz. Adjustable power: 3–100 W. Dimmable LEDs (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 mm². Color: White. Easy to use: The LED controller allows dimming adjustment via a rotary knob to set desired brightness levels. Turn the knob clockwise to increase brightness to maximum. Turn counterclockwise to decrease brightness. Safety protection: Built-in electronic overheating protection. Automatically turns off when temperature reaches 80°C and resumes operation when temperature drops below 80°C. Note: Only dimmable LEDs should be used to prevent flickering. LED load must not be less than 3W. LED lamps must be compatible with trailing-edge dimmers. If the light does not reach full brightness at maximum setting or fails to dim properly at minimum setting, and fine adjustment via the screw is ineffective, the luminaire may have a limited built-in dimming range.
