Automatic Voltage Controller/ Servo Stabilizer
Automatic voltage controller (AVC) is a device designed to maintain a constant voltage level in electrical systems, ensuring stable power supply and protecting equipment from voltage fluctuations. AVCs are commonly used in power distribution networks and industrial applications. AVC/Servo Stabilizer is usually applied at the LT side to ensure constant voltage supply to the incoming panel.
Reduce failure rate of Electrical equipments and Save energy by installing Automatic Voltage Controller
(A breakthrough in energy conservation)
Our AVC primarily consists of the following key components housed in the same tank
- Linear +/- Vertical Rolling Contact on-load Voltage Controller
- Double Wound Buck/Boost Transformer
- Control Panel with Microprocessor based control module
