GTZW-S Three Phase SCR/Non-Contact AC Automatic Voltage Stabilizer
Product principle
The voltage stabilizer consists of a voltage regulating circuit, a control circuit, and a subsequent motor.When the input voltage or load changes, the control circuit is sampled, compared, amplified, and then drives the servo motor to rotate, so that the position of the carbon brush of the voltage regulator is changed and changed, and the ratio of the number of turns of the whole coil is adjusted automatically, so as to keep the output voltage stable.
