20kva Air Cooled Servo Voltage Stabilizer 3 Phase - Output Voltage: 400 Volt (V)

The 20 KVA Air-Cooled Servo Voltage Stabilizer is an automatic three-phase voltage regulation device engineered to protect industrial and commercial equipment from power supply fluctuations. It continuously monitors the incoming voltage and adjusts it in real time using a high-precision servo motor and variable transformer system, ensuring a stable and reliable output (typically around 400 V / 415 V 1%) even when the input voltage varies widely. This stabilizer is ideal for environments with frequent voltage inconsistencies, safeguarding sensitive machinery and electronics against undervoltage, overvoltage, surges, and spikes.

The air-cooled design keeps the stabilizer lightweight, low-maintenance, and suitable for indoor installations without the need for oil cooling systems. With a fully automatic microcontroller-based control system, digital display panel, and multiple built-in protections (including overload, short circuit, phase reversal, and phase failure safeguards), it enhances equipment performance, extends operational life, and improves power quality for three-phase loads.
