Common Questions for Overseas Use
How to choose between 3.3kV and 4.5kV models?
Select based on equipment voltage requirements: 3.3kV for medium-voltage industrial frequency converters and rail auxiliary power supplies; 4.5kV for high-voltage motor drives and HVDC transmission.
HC or HG package for outdoor vs indoor use?
HC standard insulation for indoor dry environments; HG high insulation for outdoor and high-humidity environments to prevent moisture damage.
What about heat dissipation requirements?
All models require forced water cooling. Ensure proper thermal contact with water-cooled plates and maintain thermal resistance around 0.04K/W.
