Excellent work performance: large power switch power supply with 5~10s delay detect circuit design, can avoid instantaneous output and instable high voltage; Short circuit, overload, over voltage protection; 5~10 seconds delay detection circuit design, good to eliminate the power electricity output, high voltage instability, to prevent the load from the impact of the high voltage (especially LED power supply, to minimize work voltage mutation caused by the light failure); Working efficiency: 82%; Easy and convenient to install; 2-year quality insurance
