1. What is the SBW-2000 kVA AVR?
It is a high-capacity three-phase automatic voltage stabilizer for heavy industrial and commercial applications.

2. Where is SBW-2000 kVA used?
In steel plants, oil & gas, textile industries, hospitals, telecom hubs, airports, mining, and data centers.

3. Is it single-phase or three-phase?
SBW-2000 kVA is a three-phase stabilizer.

4. What is the difference between SBW and SBW-F models?
SBW-F models regulate each phase separately, ideal for unbalanced loads.

5. What is the input voltage range?
Standard ±20% (304V–456V for 380V systems), customizable to ±25% or ±30%.

6. What is the output voltage?
Stable 380V ±2% three-phase output.

7. How accurate is the regulation?
Typically ±2%, adjustable to ±1%–±5%.

8. What is the response time?
≤1.5 seconds for a 10% voltage deviation.

9. Can it handle overloads?
Yes, it can sustain 150%–200% overloads briefly.

10. What protections are built in?
Overvoltage, undervoltage, overload, short circuit, phase loss, phase reversal, and bypass.

11. Does it include an automatic bypass system?
Yes, it shifts to bypass if the AVR is overloaded or out of range.

12. What is the efficiency level?
High efficiency of ≥95%–98%.

13. Does it affect the waveform?
No, the output remains a clean sine wave.

14. What is the working temperature range?
–10 °C to +40 °C under rated load.

15. What is the allowable humidity?
≤90% relative humidity, non-condensing.

16. How is cabling handled?
Requires large-capacity copper busbars or cables sized for high current.

17. What maintenance is required?
Dust cleaning, brush inspection, tightening connections, and thermal checks every 6 months.

18. How does it react to missing or reversed phases?
It automatically shuts down to protect connected equipment.

19. Does it have a delayed start function?
Yes, to prevent inrush current during power-up.

20. Can input voltage range be customized?
Yes, extended ranges are available on request.

21. What is the insulation strength?
Withstands 2000V for one minute without failure.

22. Is it suitable for continuous operation?

Generally ≤55 dB in normal operation.

24. What are the physical dimensions and weight?
Large floor-standing cabinet; typically weighs over 2.5 tons.

25. What is the enclosure rating?
Standard IP21; IP54 models are available for outdoor installation.

26. How does split-phase regulation work?
Each phase is stabilized independently for better balance.

27. What imbalance tolerance does it have?
Can handle significant phase imbalance compared to traditional stabilizers.

28. How should I select the proper AVR size?
Choose 1.2–1.5× load capacity to cover surges and expansions.

29. What happens if input exceeds correction range?
The AVR bypasses or shuts down safely to protect equipment.

30. What warranty is offered?
Typically 12 months warranty with lifetime technical support (supplier dependent).
