Brief introduction

Main Advantage

1. Excellent output voltage waveform, stable regulating process, no lost electricity phenomenon.

2. High accuracy of output voltage, generally it is fixed in 220±3% when leave the factory, wide input voltage range, strong load adaptability with satisfiable load property.

3. It has under-voltage, over-voltage and over-current protection function. It can cut off the power supply automatically to ensure the safety of the consumer when output voltage is over-high or the input current is over-current.

4. It adopts high breaking capacity mini circuit breaker with the over-voltage protection function when it is over load or short-circuit. It uses high property carbon brush which prolong the service voltage regulator.
