Dimmer Module Home Automation And Voice Control 300w Dimmer Module Light Dimmer Light Switch Easy To Install Description: 1. This product is made of PC plastic shell, strong and wear-resistant, flame retardant, pressure resistant, energy-saving and durable. 2. Class 1 safety protection design, built-in IC control chip, anti short circuit, anti overvoltage, anti overload, over temperature protection. 3. Using PFC high efficiency factor, high efficiency and energy saving, high power utilization, no pollution to power grid 4. Output mode: constant current output, good performance. 5. Easy to install, no flash frequency, 5-year warranty. 6. The input and output wires are made of rubber cable, which is resistant to high and low temperature and is not easy to aging. 7. Open circuit protection: when there is no load and open circuit at the output end. The input is normal. The product will not be damaged. 8. Short circuit protection: if the output terminal is abnormal, the output positive and negative poles will be short circuited. This product will start the short circuit protection function and will not cause permanent damage due to this abnormality. 9. Overload protection: This product is designed with constant current, and the output current of the load will be constant within the design range. When the output load exceeds the design range, the product enters two protection states. 10. Over power protection: if the power of LED lamps is too high due to heating, this power supply can start the over power protection to ensure that the LED lamp beads are not damaged at the first time and the loss is minimized. Specifications: Input voltage: 110V / & 240V / Output power: 300W Efficiency: 85% Constant current accuracy: 5% Power factor: > 0.95 Package Included: 1* Dimmer Module Light 1*English user manual
