Our 20KVA 3 Phase Servo Type Voltage Regulator (TNS/SVC series) is a high-performance industrial automatic voltage stabilization solution, designed to deliver consistent, reliable power for global industrial and commercial applications. Part of our 6KVA to 120KVA standard regulator lineup, it features a default 304V-456V 3-phase input range (176V-264V single-phase optional) with fully customizable voltage specifications to match regional grid requirements.
Built with core components including 100% purple copper coils, high-torque servo motor, intelligent microcomputer control board, and high-conductivity double carbon brushes, it operates with seamless precision: when grid voltage fluctuates or load changes, the control circuit drives the servo motor to adjust the carbon brush position along the coil, maintaining stable output voltage continuously. It is perfectly suited for factory power systems, CNC machine tools, laser cutters, photovoltaic systems, AI data centers, EV charging stations, generators, motors, and all precision industrial equipment, eliminating voltage-related downtime and asset damage.
Key Features & Competitive Advantages
High Precision & Fast Response: ±2% output accuracy with ultra-fast servo adjustment, delivering real-time correction for voltage fluctuations
High Efficiency & Long Lifespan: Full-capacity copper coil design minimizes losses, with high-grade raw materials ensuring reliable long-term operation
Zero Waveform Distortion: No additional harmonic distortion, fully compatible with inductive, capacitive, and resistive loads
Comprehensive Protection: Built-in over-voltage, under-voltage, over-current, overload, and short-circuit protection
