General Introduction
The DBW series single phase full-automatic compensated voltage stabilizer is designed to stabilize AC voltage on the basis of advanced technology introduced from west Europe. When voltage fluctuation occurs as a result of unstable mains supply or change of loads, our product will automatically maintain stable voltage output to guarantee the normal working of connected equipment.
Features
1. Compared with other similar products, this full-automatic compensated voltage stabilizer shows the advantages of larger capacity, higher efficiency, no waveform distortion, balanced voltage regulation and many more.
2. This product fits for a wide range of loads, and transient overload is acceptable. Meanwhile, it could work continuously for quite a long time, and diverse protections are also achieved.
3. Aside from the above, this device is also famous for its small size, light weight, easy use, convenient installation, reliable performance, free switch between manual mode and automatic mode, etc.
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 in the working place, while steam, dust, dirt, chemical deposition, explosive medium and corrosive medium should also be avoided.
5. This full-automatic compensated voltage stabilizer is designed for indoor use, and the installation site must get rid of serious vibration.
Technical Parameters
1. Input voltage: Single phase 220V±20% or 220V±30% (please specify when ordering)
2. Output voltage: Single phase 220V
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. Start method: Automatically or manually
10. Working mode: Long-term unattended operation is acceptable.
11. Insulation resistance: ≥2MΩ
12. Dielectric strength: Tested at power frequency sinusoidal voltage 2000V for 1min, breakdown and flashover should be avoided.
Applications
This full-automatic compensated voltage stabilizer is suitable for elevator, television, air conditioner, lighting system, household appliance, medical apparatus, production line, textile machinery, metal processing equipment, large electromechanical device, constructional engineering equipment and many more.
