Product Overview
The YIMAI Three-Phase Automatic Voltage Regulator (AVR) is an industrial-grade power stabilization system engineered to provide precise, stable three-phase power for heavy-duty loads. Utilizing advanced servo-motor control and high-quality copper windings, this AVR automatically adjusts wide input voltage fluctuations (typically 280V~430V AC) to a precise 380V±1% output, protecting sensitive industrial equipment from damage caused by over-voltage, under-voltage, and power surges. Available in capacities from 10kVA to 500kVA, it is the ideal solution for factories, mines, data centers, and other industrial applications where power stability is critical.
Core Technical Advantages
-
High-Precision Servo-Motor ControlThe voltage stabilizer employs a high-speed servo motor to drive the voltage regulator, ensuring fast response time (<1 second) and precise output voltage regulation (±1%), effectively eliminating voltage fluctuations and providing stable three-phase power to connected loads.
-
Ultra-Wide Input Voltage RangeIt accepts an ultra-wide input voltage range (typically 280V~430V AC, three-phase), making it suitable for areas with extremely unstable power grids, where voltage often drops below 300V or spikes above 420V. This wide range ensures continuous operation even under the most extreme power conditions.
-
Robust Industrial Design & Durability
- Uses high-conductivity copper coils and high-permeability silicon steel cores, ensuring low energy loss and high efficiency (>92%).
- The heavy-duty metal cabinet with a sloped roof provides excellent heat dissipation, weather resistance, and mechanical protection, extending the service life to 20+ years.
- Front-panel analog meters and indicator lights allow for real-time monitoring of input/output voltage, load status, and operating conditions.
-
Comprehensive Multi-Layer Protection MechanismsThe system is equipped with a full suite of built-in protections:
- Over-voltage protection (OVP): Automatically cuts off power when output voltage exceeds safe levels.
- Under-voltage protection (UVP): Disconnects the load when input voltage drops below the minimum threshold.
- Over-load protection (OLP): Shuts down to prevent damage when the load exceeds the rated capacity.
- Short-circuit protection: Safeguards against short circuits in the connected equipment.
- Phase sequence & phase loss protection: Prevents damage from incorrect phase wiring or missing phases.
- Surge & lightning protection: Filters out high-voltage spikes caused by lightning or grid switching.
- Over-temperature protection: Prevents overheating of internal components.
-
Easy Operation & Maintenance
- The front-panel control interface features analog meters, push buttons, and indicator lights for intuitive operation and status monitoring.
- The cabinet door with a lock ensures physical security and easy access for maintenance.
- Modular design allows for easy replacement of components, reducing downtime and maintenance costs.
-
Flexible Customization
- Supports custom input voltage ranges (e.g., 220V~480V AC) and output voltages (e.g., 400V, 415V) to meet different regional grid requirements.
- Can be customized with additional features: remote monitoring (RS485/Modbus), bypass switch, and parallel operation for higher capacity requirements.

Q2: Can this stabilizer handle a 50kVA load?
A: The 50kVA model has a rated capacity of 50kVA, with a typical power factor of 0.8, so the maximum continuous load is approximately 40kW. It is recommended to keep the load below 80% of the rated capacity for optimal performance and longevity.
Q3: What is the input voltage range? Can it work in areas with very low voltage?
A: The standard input range is 280V~430V AC (three-phase). We also offer custom models with an even wider input range (220V~480V AC) for regions with extremely unstable power grids.
Q4: Is the output voltage always 380V? Can it be adjusted?
A: The output voltage is fixed at 380V AC ±1% for stable operation. Some models allow for minor adjustments (±5%) via an internal potentiometer, depending on the configuration.
Q5: Does this stabilizer protect against phase loss and phase sequence errors?
A: Yes, it includes built-in phase sequence and phase loss protection, preventing damage to three-phase motors and equipment from incorrect wiring or missing phases.
Q6: How noisy is the stabilizer during operation?
A: The noise level is <65dB for 50kVA models, <68dB for 200kVA models, and <70dB for 500kVA models, which is acceptable for most industrial environments.
Q7: Can I connect multiple stabilizers in parallel for higher capacity?
A: Yes, we offer parallel operation options for models up to 500kVA, allowing you to scale up the total capacity to meet larger load requirements.
Q8: Is this stabilizer suitable for outdoor installation?
A: Yes, the cabinet is designed with a sloped roof and weather-resistant metal enclosure, making it suitable for outdoor installation in rain, snow, and dust environments.
Q9: What is the warranty period? What after-sales support is provided?
A: All three-phase AVR cabinets come with a 3-year warranty, and we offer lifetime technical support, including on-site installation, maintenance, and emergency repair services worldwide.
