Description

This is a double-conversion online UPS in a transformer-based design. The input rectifier is built on IGBTs, and dual DSP handles the control. A power factor of 0.9 means active power in kW is about a tenth lower than apparent power in kVA, and this difference is accounted for when sizing for servers and motors. The front panel carries a 7 inch touchscreen, and the EPO input makes it possible to de-energize the unit in an emergency from a button in the machine room. The power range spans the way from a small server room to a large power node, so one platform can be used at different sites.

How to choose

First determine the apparent power in kVA taking the 0.9 factor into account, since the frame size in the 10–600 kVA range depends on it. For the lower range up to 80 kVA there is the UD series with the same 3:3 scheme and N+X redundancy. The high-frequency YDC3300 at 10–200 kVA has efficiency up to 95.8% and parallel operation of up to 8 UPS units, and for a single-phase output from a three-phase input there is the UCR at 6–10 kVA with a 3:1 scheme. If you need transformer isolation and maximum power, choose the EPOWER-H.

FAQ

What power does the three-phase EPOWER-H cover?

The model range covers 10–600 kVA. The phase configuration is 3:3, so both input and output are three-phase.

What is the power factor of the EPOWER-H?

The power factor is 0.9. For the active load in kW take 0.9 of the rated kVA.

Which rectifier does the EPOWER-H transformer-based UPS use?

The rectifier is built on IGBTs, with dual DSP control. The design is transformer-based, for data centers and industrial loads.

How is the EPOWER-H shut down in an emergency?

Through the EPO input. The front panel also has a 7 inch touchscreen for setup and monitoring.

Which UPS should I take if only 10–80 kVA is needed?

For that range there is the UD series with a three-phase 3:3 scheme. The EPOWER-H makes sense when power has to reach 600 kVA.
