UPS AND POWER SUPPLIES

KSTAR UCR online UPS 6–10 kVA 3:1 rack/tower

Supplied as an official KSTAR partner

Manufacturer: KSTAR · China · Model: UCR

The UCR online UPS is rated 6–10 kVA with a three-phase input and single-phase output (3:1), in a rack/tower case. Double conversion with DSP control isolates the load from the grid, and N+X parallel operation gives a reserve for critical IT equipment.

Description

The inverter continuously forms the output voltage here, so grid faults do not reach servers and switches. The case is placed as a tower or in a rack, and the display rotates to suit the chosen position. A power factor of 0.9 means the load in kW is 0.9 of the rating in kVA; this difference is taken into account when sizing a UPS for servers. For fault-tolerant setups, units are connected in parallel on the N+X principle, where X extra UPS units back up the N that are needed. The EPO input is meant for emergency shutdown, for example from a button at the entrance to the machine room.

How to choose

The choice is set by power within 6–10 kVA and the 3:1 phase configuration. If the supply is single-phase, there is the MEMOPOWER-III at 1–10 kVA with an input power factor of 0.99 and efficiency up to 94% in the 6–10 kVA RT version. For a three-phase 3:3 output, take the UD at 10–80 kVA or the YDC3300 at 10–200 kVA with efficiency up to 95.8%. When capacity has to grow in hot-swap modules, the HPM3300E at 10–150 kVA fits.

FAQ

What does the 3:1 phase configuration of the UCR mean?

The 3:1 designation reads as a three-phase input and a single-phase output. The UPS is connected to a three-phase grid, while the load is fed from one phase.

What is the active power of the UCR in kW?

The power factor is 0.9, so active power equals 0.9 of the rating in kVA. The unit is rated 6–10 kVA.

Can several UCR units be connected in parallel?

Yes, parallel operation in an N+X scheme is provided. The number of units is not stated in the data and should be checked in the technical description.

What is the EPO function in the UCR for?

EPO is an emergency power-off input. With a single contact, for example from a button, the UPS is taken off the output circuit.
