Master HP / Master HE — three-phase transformer-based UPS 100–800 kVA
Country: Italy · Model: Master HP / Master HE
The Master HP and Master HE transformer-based online UPS units cover 100–800 kVA and target data centers and industrial loads. The IGBT rectifier barely affects the source (THDi <3 %), and the output transformer isolates the load from the batteries.
- Power
- Master HP — 100–600 kVA (90–540 kW); Master HE — 100–800 kVA/kW (PF = 1); Master HP UL — 65–500 kVA (480 V, 60 Hz, UL/CSA)
- Topology
- online, VFI-SS-111, IGBT rectifier, output isolation transformer
- Efficiency
- Master HP — up to 94.5 %, Master HE — up to 95.5 % (online); up to 99.4 % in STANDBY ON mode
- Input
- 380/400/415 V, THDi <3 %, PF >0.99

Description
Master HP comes in 100–600 kVA (90–540 kW) with up to 94.5 % efficiency, Master HE in 100–800 kVA/kW at PF 1 with up to 95.5 % in online mode. In STANDBY ON mode efficiency reaches 99.4 %. For 480 V, 60 Hz grids there is the Master HP UL at 65–500 kVA with UL/CSA certification. Master HE handles peak shaving and Smart Grid operation. The input takes 380/400/415 V at PF >0.99, so a diesel generator can be sized close to the UPS rating. The UPS carries 110 % overload for 60 min, 125 % for 10 min and 150 % for 1 min. Dimensions run from 800×850×1900 to 2100×1000×1900 mm for 100–600 kVA, and IP20 calls for a clean, dry room. It accepts VRLA AGM/GEL, NiCd and Li-ion batteries, supercapacitors and flywheels. Large parallel systems use the centralized MSB static bypass rated 800–3000 kVA.
How to choose
The load power factor decides between the series, and at PF 1 above 600 kVA only Master HE remains. The transformer design is needed where galvanic isolation matters. Without that need, and with up to 97 % online efficiency in view, consider the transformerless NextEnergy NXE at 250–800 kVA/kW. Smaller loads go to Master MPS at 10–200 kVA.
