NextEnergy NXE — transformerless three-phase UPS 250–800 kVA
Country: Italy · Model: NextEnergy NXE
Rated 250–800 kVA/kW, the transformerless three-phase NextEnergy NXE UPS delivers full power at PF = 1 up to 40 °C. It goes into data centers and critical facilities where the UPS is also expected to do peak shaving and act as an active filter in ACTIVE ECO mode.

Description
The power stage uses a three-level IGBT inverter in VFI-SS-111 online topology with no output transformer. Efficiency is up to 97 % online, 98.5 % in ACTIVE ECO and 99 % in STANDBY. The ECS system keeps efficiency high at partial load, and since redundant data center UPS almost always run underloaded, the room gets less heat. The unit runs without a neutral, so a three-wire feeder from the transformer is enough. The cabinet is serviced entirely from the front and can stand against a wall or back to back with other cabinets. Cables enter from the top or bottom, which suits both cable trays and raised floors. Setup and monitoring go through a 7″ touch display. Storage can be VRLA, AGM, GEL, NiCd or Li-ion batteries, supercapacitors or flywheels.
How to choose
Size the unit for the design load with margin and build redundancy through parallel operation of up to 8 UPS with expansion without shutdown (HSE), so the system can start with one spare unit and grow later. For loads under 250 kVA, look at the Master MPS, rated 10–200 kVA with an isolating transformer on the inverter. If the project calls for an output transformer at 100–800 kVA, take the Master HE with up to 95.5 % online efficiency. For a modular layout with hot-swap power modules there is the Multi Power2, 120–600 kW in one cabinet with up to 98.1 % efficiency.

FAQ
What efficiency does the NextEnergy NXE UPS reach?
Up to 97 % online, 98.5 % in ACTIVE ECO and 99 % in STANDBY. At partial load the ECS system keeps efficiency up.
How many NXE units can run in parallel?
Up to 8 units. A new unit is added without shutting the system down (HSE).
Does the NextEnergy NXE need a neutral?
No, the UPS runs without a neutral across the whole 250–800 kVA/kW range.
What energy storage works with the NextEnergy NXE?
Lead-acid VRLA, AGM and GEL batteries, NiCd, Li-ion, supercapacitors and flywheels.
Can the NXE stand against a wall?
Yes, service access is needed only from the front, and cables enter from the top or bottom.
