    3 phase voltage stabilizer details



    In fact, the three-phase voltage stabilizer connects the three voltage stabilizing units with "Y" connection method, and then uses the control circuit board and the motor drive system to control the voltage regulating transformer, so as to achieve the function of stabilizing the output voltage.

    If the sliding arms of the three voltage regulating transformers are driven by one motor, the voltage regulating mode is the unified voltage stabilizer. If the sliding arms of the three voltage regulating transformers are independently adjusted by three motors, the three-phase split regulation voltage stabilizer is the same as the single-phase voltage stabilizer.

    In the process of voltage regulation, the regulator is realized by moving the carbon brush to change the number of contact coil turns. Then, during the adjustment, it is required to keep contact with the coil at all times, otherwise, the power will be cut off.

    What is the difference between a Voltage Stabilizer you proivde and an AVR?
    1. What is the difference between a Voltage Stabilizer you proivde and an AVR? Does one have any advantage over the other?
    2. Does the Voltage Stablizer you specified for me have any delay in voltage correction?

    1. Automatic voltage stabilizer output is fixed value with approx +/- 2% tolerance like in your case, but AVR (automatic voltage regulator) output may be a range. So in your case, automatic voltage stabilizer is the most suited as you mentioned below "my main purpose is to control steady voltage to a machine".
    2. Our voltage stabilizer has high response time ≤1.5S.

    30 kVA 3 phase Industrial AC Automatic Voltage Stabilizer

    SKU: ATO-AVS-3P30K
    Energy saving 30 kVA full automatic voltage stabilizer is designed for industrial machine requirement with servo motor. Default three phase 304V-456V AC input (+/- 20% tolerance) and 380V output, input/ output voltage is customizable as you need. When the supply voltage of the distribution network fluctuates or the load changes, the voltage regulator will stabilize the output voltage automatically.
