Introduction

SDR serie is composed of a contact-type auto-transformer, a servo motor, a control circuit, etc. When the grid voltage is unstable or the load changes, the voltage stabilizer automatically samples the signal, and the control circuit sends a signal to drive the servo motor. The motor adjusts the position of the carbon brush on the auto-transformer to regulate the output voltage of the stabilizer to the rated value and maintain a stable state.This series of voltage stabilizers features small size, light weight, and simple structure. It can be widely used in various residential, commercial, and industrial power supply applications.
