❓ FAQs
How should I set DC voltage/current set-points?
🔸 The 200–950 Vdc range delivers full power above 500 Vdc; if operating below 500 Vdc, apply an appropriate derating margin.
What AC current should be provisioned?
🔸 The nominal current is ~1732 A at 400 Vac three-phase—select breakers, busbars, and cabling to match this rating.
Is outdoor installation possible?
🔸 Prefer installation in electrical rooms/containers with forced-air cooling and protection against dust/moisture; the enclosure can be customized for site conditions.
Does it integrate with PCS and SCADA?
🔸 Yes—operates as an AC-DC rectifier within DC-coupled architectures alongside PCS, communicating via RS485/CAN per the site’s control design.
