100Kva-4000Kva Three-Phase Fully Automatic Intelligent Igbt Based Static Voltage Stabilizer

Core Benefits

Ultra‑Fast Response: Electronic regulation via IGBT adjusts output within < 10 ms, eliminating harmful dips and spikes.

High Precision & Efficiency: Maintains 380 V ± 1% (customizable) with ≥ 98% efficiency at full load, reducing energy waste and operating costs.

Zero Mechanical Wear: Fully solid‑state design extends service life (≥ 150,000 h) and minimizes maintenance.

Wide Input Range: Handles three‑phase 304–456 V fluctuations (± 20%, up to ± 60% optional) without interruption.

Intelligent Regulation

Three‑Phase Independent Control: Balances voltage across all phases, even under unbalanced grid conditions.

Real‑Time Monitoring: 5″ LCD displays input/output per phase, load current, temperature, and fault codes.

Remote Access: RS485/Modbus interface for seamless integration with SCADA or BMS systems.

Safety & Protection: Over/Under‑Voltage Cutoff at ± 10% of rated output (e.g., 342 V/418 V).

Overload & Short‑Circuit Protection: 150% overload for 5 min, 200% for 1 min; built‑in current limiting.

Three‑Phase Imbalance Guard: Automatically corrects phase imbalances to protect motors and transformers.

Thermal Management: Forced‑air IP54 fans (water cooling optional) and 120 °C cutoff sensor.

Manual Bypass: Copper busbar ensures uninterrupted power during maintenance.
