Digital Ac Voltage Regulator Series 65306 High Power Factor - China

I.

Product Introduction

High power factor digital voltage regulator includes single- phase voltage regulator and three- phase voltage regulator, as an AC voltage regulator, it adopts an integrated design combining two or more sets of digital power controllers and a load- matching transformer with two or more sets of output voltage grading taps and it realizes the waveform superimposition and continuous regulation of output voltage by the way of alternative phase shift & voltage regulation at the voltage grading taps of the primary side of the load- matching transformer.

It has open- loop or various closed- loop control forms and multiple given control signal selections.

The power factor and current harmonics of traditional SCR voltage regulators vary with the changes of the SCR’s conducting angle, the output voltage waveform is waveform with unfilled corners, the power factor is low and the current harmonics are big.

After the waveform superimposition technique is adopted on two or more sets of output voltages, a full non- sinusoidal waveform of output voltage magnitude can be realized, according to the power demand curve of the actual load, it can not only meet the high power demand during rapid temperature rise but also can meet the low power demand at constant temperature, thus, with rational grading of matched- load voltage, it improves the power factor and lowers the current harmonics effectively and it can be widely used in the continuous regulation and control of single- phase or three- phase AC power of automatic temperature control systems such as various industrial heating and heat treatment system etc.
