Product Details

300KVA AC purifying regulated power supply

1.Product introduction

The GTJW Intelligent ac voltage stabilized power supply is used single chip microprocessor control chip and high power field effect tube or IGBT element control of a high performance electronic ac power voltage equipment.

It combines purification, voltage regulator, automatic protection and anti-jamming multi-function at an organic whole, fast response speed and good output waveform, working voltage and frequency stability, high precision, strong anti-interference, resistance to impact load capacity and reliable, etc No mechanical transmission device and no mechanical contact, thus has the advantages of long service life, low noise, no maintenance.

It used in the areas of power grid voltage fluctuation is frequent, and the requirements for power supply electrical equipment of high quality.

2. working principle

Controlled by single chip microprocessor chip and high power field effect tube or IGBT element control, depending on the bidirectional thyristor conduction Angle and form the equivalent inductance of different, make the output to the input changes to compensate for voltage stability principle

3.Features

Free maintenance, anti-jamming, high precision of voltage regulation, voltage regulation speed, can effectively inhibit the grid peak and all kinds of noise and interference, no carbon brush wear, no motor drive, no spark of arc.
