Product Description

1. Product Introduction

SBW 250KVA Voltage Regulator is composed of a voltage stabilizer circuit, a control circuit, and a servo motor. When the input voltage or load changes, the control circuit samples, compares, and amplifies, and then drives the servo motor to rotate to change the position of the carbon brush of the voltage stabilizer. The coil turns ratio is automatically adjusted to keep the output voltage stable. When the voltage fluctuates then the Voltage Stabilizer will adjust to rated value and run a steady state.
