Three Phase Full-Automatic Compensated Voltage Stabilizer

Our company introduces leading-edge technologies from west Europe to manufacture SBW series three phase full-automatic compensated voltage stabilizer, and this product is able to offer stable voltage output regardless of mains supply fluctuation and load condition change.

In contrast to other types, this device possesses higher efficiency, larger capacity, no waveform distortion, balanced voltage regulation and other advantages. It is also characterized by small size, light weight, reliable running, convenient installation, free switch between manual mode and automatic mode, etc. Moreover, this three phase voltage stabilizer is applicable for various kinds of loads, while transient overload and long-term continuous running are both acceptable.

Regular Working Condition
1. Ambient temperature: -15℃ to +40℃
2. Altitude: <1000m
3. Relative humidity: < 90%
4. There should be no such kind of gas that can seriously deteriorate the insulation performance, while steam, dust, dirt, chemical deposition, explosive medium and corrosive medium should also be avoided.
5. This three phase voltage stabilizer is designed for indoor use, and the installation site must get rid of serious vibration.

Technical Parameters
1. Input voltage: Three phase four wire, 380V±20% or 380V±30% (please specify when ordering)
2. Output voltage: Three phase four wire, 380V (line voltage) or 220V (phase voltage)
3. Output voltage precision: Adjustable within 2%-5%
4. Frequency: 50-60Hz
5. Efficiency: ≥95% (for power ratings over 50KVA)
6. Response time: ≤1.5 seconds when voltage changes by 10%
7. Waveform distortion: No additional distortion
8. Protections: Overvoltage, over current, mechanical fault, phase loss, phase sequence (phase loss and phase sequence protections are not provided for models whose capacities are lower than 150KVA)
9. Switch function: Free switch between mains supply and regulated voltage
10. Start method: Automatically or manually
11. Working mode: Long-term unattended operation is acceptable.
12. Insulation resistance: ≥2MΩ
13. Dielectric strength: Tested at power frequency sinusoidal voltage 2000V for 1min, breakdown and flashover should be avoided.

Applications
The three phase voltage stabilizer has found wide applications in various fields including industry, agriculture, transportation, telecommunication, railway, military, scientific research, etc. The applicable equipment covers elevators, home appliances, lighting systems, production lines, medical instruments, constructional engineering machines, large electromechanical devices, metal processing machinery, and many others that require stable voltage supply.
