Data Centers & IT Rooms
Racks that already have two independent feeders and cannot accept a slow mechanical transfer.
Most IT power supplies will ride through a dip measured in milliseconds. They will not ride through a mechanical ATS. The HPS static transfer switch is specified at a typical ≤6 ms SCR transfer between two independent sources, with Source A as priority.
Current steps run 63 A to 400 A per phase at a published 380 V ±15%. Efficiency is ≥98%. We do not claim Tier ratings — none of that is on the source page.
