Three Phase Adjustable Voltage Stabilizer

The Three Phase Adjustable Voltage Stabilizer (three phase split voltage stabilizer) is built to keep critical equipment running with a stable, regulated output even when the grid voltage fluctuates. Featuring a fast response control system, clear display screen, and simple front panel operation, it is easy to adjust and suitable for long term unattended operation. Typical rated capacity spans 10kVA–2000kVA. For three phase four wire systems, the input voltage is commonly 176–264V (phase voltage) / 304–456V (line voltage), and the input tolerance can be configured to ±15%, ±20%, or ±30% (customizable). Output voltage is typically 220V (phase) / 380V (line) (customizable). Regulation accuracy is ±(2% to 5%) adjustable, with waveform distortion ≤ 0.1% and response time <1.5s when input voltage changes by 10%. The stabilizer includes comprehensive protections (over/under voltage, overcurrent, phase loss, etc.) and supports automatic/manual bypass to ensure power continuity during faults or maintenance. Common applications include public facilities distribution, medical equipment, industrial production lines, and new energy systems. (Specifications can be customized—please confirm final data when ordering.)

Key Features

• Fast Regulation: Response time <1.5s (typ.) for a 10% input change, helping protect sensitive loads from voltage dips and surges.
• Wide Input Range: Configurable input tolerance ±15% / ±20% / ±30% (customizable) for unstable power environments.
• Adjustable Accuracy: Output Voltage Accuracy ±(2%–5%) adjustable to match different equipment requirements.
• Auto/Manual Bypass: Continuously switch to mains power during faults; manual bypass for maintenance and service.
• Safety Protections: Over/under voltage, overcurrent and phase loss protection for safer operation with complex loads.
• Industrial Cabinet + HMI: Robust enclosure, clear indicators/screen, simple operation, air cooled design for stable long term running.
