1. What is the SBW-1600 kVA AVR?
It is a high-capacity three-phase automatic voltage stabilizer designed for large-scale industrial and commercial operations.
2. Where is SBW-1600 kVA used?
It is ideal for power-intensive industries such as steel mills, oil & gas, hospitals, data centers, airports, telecom, and heavy manufacturing plants.
3. Is it a single-phase or three-phase system?
The SBW-1600 kVA AVR is a three-phase stabilizer.
4. What is the difference between SBW and SBW-F models?
SBW-F models stabilize each phase independently, ensuring better performance with unbalanced loads.
5. What is the input voltage range?
Normally ±20% of nominal (304V–456V for a 380V system). Custom wider ranges are available.
6. What is the output voltage?
A regulated 380V ±2% three-phase output.
7. How precise is the regulation?
Accuracy is ±2%, adjustable between ±1%–±5%.
8. What is the response time?
≤1.5 seconds to correct sudden voltage changes.
9. Can it handle overloads?
Yes, it withstands 150%–200% overloads for short periods.
10. What protections are included?
Overvoltage, undervoltage, overload, short circuit, phase loss, phase reversal, and automatic bypass.
11. Does it include an automatic bypass system?
Yes, it switches to bypass if input voltage is out of range or in case of internal failure.
12. What is the efficiency level?
High efficiency ≥95%–98%, ensuring minimal power loss.
13. Does it distort the waveform?
No, it maintains a clean sine wave output.
14. What is the allowable temperature range?
–10 °C to +40 °C under rated load.
15. What is the humidity tolerance?
≤90% relative humidity (non-condensing).
16. How is wiring managed for SBW-1600 kVA?
Requires heavy-duty copper busbars or cables sized for rated current.
17. What are the maintenance requirements?
Regular cleaning, brush inspection, tightening of terminals, and thermal checks every 6 months.
18. How does it respond to missing or reversed phases?
The AVR shuts down automatically to protect connected equipment.
19. Does it feature a start-up delay?
Yes, built-in delay prevents inrush current issues.
20. Can the input range be customized?
Yes, ±25% or ±30% options are available.
21. What is the insulation strength?
Withstands 2000V for one minute without insulation failure.
22. Can it operate continuously?
Yes, it is built for 24/7 continuous duty operation.
23. What is the noise level?
Typically ≤55 dB, ensuring quiet operation.
24. What are the dimensions and weight?
Large cabinet system weighing over 2 tons; dimensions vary by supplier.
25. What is the enclosure protection rating?
Standard IP21; higher IP ratings (IP54) available for outdoor models.
26. How does split-phase regulation help?
It balances each phase individually, improving stability under unbalanced loads.
27. How much phase imbalance can it tolerate?
Handles higher imbalance than standard AVRs, reducing risks to equipment.
28. How should I select the AVR capacity?
Choose 1.2–1.5× total load capacity to cover surges and future expansion.
29. What happens if input voltage goes beyond correction range?
The stabilizer either bypasses or shuts down to safeguard equipment.
30. What warranty and service support are available?
Usually 1 year warranty plus lifetime technical support (varies by supplier).
