Description

In an online scheme the load is fed through the inverter all the time, so grid sags and faults do not reach the consumer. The isolation transformer is mounted inside the UPS itself, so no separate transformer is needed in the panel. A DSP processor controls the conversion. Input power factor reaches 0.97 and output power factor is 0.8, so active power is 0.8 of the apparent power in kilovolt-amperes. Up to 6 UPS units can be connected in parallel to raise system capacity as the load grows.

How to choose

First add up the apparent power of the load in kVA and include a margin, bearing in mind the output power factor of 0.8. One unit covers 10–160 kVA, and for larger sites a parallel group of up to 6 UPS units is built. If galvanic isolation is not needed and the load does not exceed 80 kVA, look at the three-phase UD at 10–80 kVA with a power factor of 0.9. For the 10–200 kVA range and parallel operation of up to 8 UPS units, the high-frequency YDC3300 fits.

FAQ

Why does the EPOWER-L have a built-in isolation transformer?

It galvanically separates the input from the load, which is why the series is made for harsh operating conditions. No separate transformer next to the UPS is needed.

What is the power range of the EPOWER-L?

From 10 to 160 kVA, with a three-phase input and output (3:3).

How many EPOWER-L units can be run in parallel?

Up to 6 UPS units. This is how total capacity is increased when the load exceeds one unit.

What are the input and output power factors of the EPOWER-L?

Up to 0.97 at the input and 0.8 at the output. Active power in kW thus equals 0.8 of the apparent power in kVA.

What control is used in the EPOWER-L industrial UPS?

Digital control on a DSP processor.
