380V 3 Phase AC Automatic Voltage Regulators | TNS Series Industrial Voltage Stabilizer
Product Overview
Our 380V 3 Phase AC Automatic Voltage Regulators (TNS/SVC series) are industrial-grade stabilization solutions engineered for global industrial applications, with standard rated capacity from 6KVA to 120KVA (fully customizable). With a standard input range of 304V-456V (line-to-line) and 176-264V auxiliary range, this regulator is built with premium copper coils, high-torque servo motors, intelligent auto-control circuits, and high-conductivity carbon brushes. When grid voltage fluctuates or load changes, the control system drives the servo motor to adjust the carbon brush position, maintaining a stable 380V output continuously. It delivers zero additional waveform distortion, reliable 24/7 operation, and is ideal for factory power systems, CNC machine tools, photovoltaic systems, AI data centers, EV charging stations, generators, and precision industrial equipment.
Key Features & Competitive Advantages
High Precision & Fast Response: Microcomputer control board with sub-modulation technology ensures ±2% output accuracy, with rapid servo-driven adjustment to stabilize voltage in milliseconds, eliminating unplanned downtime for sensitive equipment.
Durable & High-Efficiency Design: Full purple copper coils with tight, standardized winding minimize power losses, while double high-conductivity carbon brushes extend service life, delivering full rated capacity, low energy consumption, and long-term reliable operation.
Comprehensive Protection System: Built-in over-voltage, under-voltage, over-current, overload, short-circuit, and surge protection to safeguard your valuable industrial equipment from grid anomalies and voltage spikes.
User-Friendly & Versatile: Equipped with brake wheels for flexible on-site mobility, highly insulated reliable terminals, optional pointer or digital display for real-time monitoring, and full compatibility with resistive, inductive, and capacitive loads for diverse industrial scenarios.
