Smart Three-Phase IGBT Automatic Voltage Regulator Factory From China

ZBW Series 200–2000kVA Smart Three-Phase IGBT Non-Contact Automatic Voltage Regulator Stabilizer(Fast Response LCD AVR)

The ZBW Series 200–2000kVA Smart Three-Phase Automatic Voltage Regulator (AVR) is an outstanding model of the three phase AVR stabilizer which ensures accurate and fast voltage regulation in tough conditions of heavy industrial facilities.

Based on the latest technology using microprocessor devices (MCU + high-speed AD + PLD), this automatic three phase voltage regulator monitors any changes in the input voltage and adjusts output voltage automatically due to static switching based on IGBT/SCR. As a result, a fully electronic and no contact AVR is obtained providing long-term performance without wear and tear.

Unlike classic servo voltage regulators, this automatic three phase voltage regulator ensures better performance, efficiency, and protection.
