Description

A power factor of 0.9 means the active power in kW is nine tenths of the apparent power in kVA. Keep this in mind when comparing with models that have a factor of 1.0. In double-conversion mode the load is fed from the inverter all the time, so sags, voltage surges and grid noise do not reach it. A DSP processor runs the circuit, and a digital algorithm keeps the output stable. Units can be connected in an N+X scheme, either adding capacity or adding a standby unit in case one of them fails. An ECO mode is provided to save energy, and the battery charging current is adjustable, so it is set to match the capacity of the battery string and its permissible charging current.

How to choose

First calculate the load in kW rather than kVA, with a correction for the 0.9 factor. The UD covers 10–80 kVA. For smaller ratings there is the UCR at 6–10 kVA with 3:1 phases, for higher ratings and high efficiency the YDC3300 at 10–200 kVA with efficiency up to 95.8%, and for a modular architecture the HPM3300E at 10–150 kVA. If the supply is single-phase and up to 10 kVA, look at the MEMOPOWER-III.

FAQ

What are the rating and phase configuration of the UD?

The UD is made for 10–80 kVA with 3:3 phases, meaning a three-phase input and a three-phase output.

What is the active power of the UD?

The power factor is 0.9, so active power in kW is nine tenths of the rated power in kVA.

Can several UD units be combined?

Yes, N+X redundancy is provided and is used to add capacity or a reserve.

What is the ECO mode for?

It reduces losses while the grid is normal. The battery charging current is adjusted separately.

What does double conversion give in the UD?

The load is fed from the inverter all the time, so grid sags and surges do not reach it. A DSP processor handles the control.
