LED Emergency Driver 3-25W 85-265V

The LED emergency start power supply is a device that can automatically switch to a backup power source when the mains power is cut off, providing emergency power to LED lights to ensure continuous illumination. Here is a detailed introduction to it:     Working principle: When the mains power is normal, the inverter of the LED emergency start power supply keeps the battery pack in a charging standby state, maintaining battery performance and lifespan through trickle charging. When the mains power suddenly fails, the inverter immediately switches to emergency battery pack DC power supply to ensure the lighting of the lamps.
