Product Introduction

 

It consists of 1 pcs adjusting transformer and 1 pcs compensation transformer, with sensors and control systems; managed by a state-of-the-art digital computer system.

 

The computer system calculates the difference between output voltage and programmed value; identifies the solution; the electro-servo motor rises or lowers the actuator bar which changes the winding ratio to either increase or decrease the outgoing voltage.
