Introduction: The conversion efficiency of this model is more than 85%, with output over-current protection, short circuit protection, constant output voltage and etc. Working Principle: Under AC 100-240V, power for the load is provided by electric supply. Then led light is green. When power failure is provided by the battery voltage to the load, then led light is red, the system will automatically reset when the mains power returned to normal and ready to be prepared for the next time.
