High Accuracy Full Automatic AC Voltage Stabilizer

Principle & Characteristics

This product is constructed by connecting the three pieces of high accuracy full-automatic AC voltage stabilizers with the Y connection method. It has the advantages of wide input voltage range, high efficiency, with over and under-voltage, over-current protection function, high regulation accuracy, short adjusting time, same input and output voltage waveform, small volume and less weight.

Scope of Application

It is suitable for electric equipment and facilities in housing, factory, school, shop, offices, and precision instrument for scientific research. It provides long service.
