Three-Phase Online UPS
Three-phase in, three-phase out — high-frequency online protection for data centers, plants and infrastructure.
Three-phase UPS for mission-critical loads
When the protected load runs on three-phase power — data center racks, industrial automation, medical imaging, building systems — the UPS must match. HighIdea's three-phase online systems provide full double conversion with DSP control, wide input tolerance and generator compatibility.
- EX33 (10–80kVA): tower format with high-frequency online topology, full LCD control panel, optional isolation transformer.
- 33ET (10–60kVA): rack format for standardized data center cabinets, external battery for flexible runtime.
Both families support parallel operation for redundancy or capacity growth. Battery options include classic VRLA racks or LiFePO4 packs for longer life and smaller footprint.
