Q4: Is the output voltage adjustable?
A: The output voltage is factory-set to 380V±0.5%, but we can customize it to 400V or 415V according to regional requirements before delivery.
Q5: Does it support parallel operation for higher capacity?
A: Yes, models above 500kVA support parallel operation, allowing you to combine multiple units to achieve capacities up to 1000kVA or higher.
Q6: How noisy is it during operation?
A: The noise level is <68dB for 100kVA, <70dB for 300kVA, and <72dB for 1000kVA, which is acceptable for most industrial environments.
Q7: Can it be used outdoors?
A: The standard enclosure is IP20 (indoor use). For outdoor installation, we offer custom IP54/IP55 enclosures with weatherproofing and temperature control.
Q8: What is the warranty period?
A: All SBW series AVRs come with a 3-year warranty, and we offer lifetime technical support, including on-site maintenance and emergency repair services.
