The 50KVA High Power Compensation Voltage Stabilizer is engineered for medium-to-large industrial environments where voltage consistency is essential. It combines a servo-controlled autotransformer, thermal relay protection, and an automatic control circuit to maintain precise output voltage across all three phases.
Each phase is regulated independently to ensure balanced voltage delivery under varying load conditions. The unit supports both three-phase four-wire (Y) and three-phase three-wire configurations, with ampere meters and voltage monitoring for each phase. It includes over-voltage, under-voltage, and thermal overload protection, making it suitable for equipment such as motors, compressors, CNC machines, and control systems.
With ≥90% efficiency, ≤1 second response time, and distortion-free waveform, this stabilizer is a reliable solution for facilities with unstable grid supply.
