UPS AND POWER SUPPLIES

KSTAR EP-IND-ZY industrial UPS, 10–120 kVA, 3:1, with 12-pulse rectifier

Supplied as an official KSTAR partner

Manufacturer: KSTAR · China · Model: EP-IND-ZY

The EP-IND-ZY is a transformer-type UPS rated 10–120 kVA with a three-phase input and a single-phase output (3:1). The 12-pulse rectifier and the 300–500 V AC input voltage are built for industrial networks. It is installed in the oil and gas industry, in refining, in chemicals and in industrial power engineering.

Description

This is an industrial UPS of the transformer type, meaning it has galvanic isolation, unlike the transformerless models made for offices. The rectifier is 12-pulse, which reduces harmonics in the input network compared with simpler circuits. The input accepts 300–500 V AC, which matches three-phase industrial networks. IP31 means protection against solid objects and vertically falling drops, so the cabinet goes indoors, for example in an electrical room or at a control point. The rated power is chosen within 10–120 kVA according to the load, and the 3:1 scheme means a three-phase supply with a single-phase output for instrumentation and automation loads.

How to choose

The main parameter is power in kVA, selected with a margin over the total load. The 3:1 scheme is needed when the input is three-phase and the consumers are single-phase. If you need three phases at the output, look at the UD series, 10–80 kVA, with the 3:3 scheme. For small loads of 6–10 kVA with a 3:1 output there is the UCR in a rack/tower format. When choosing between them, consider the 12-pulse rectifier and the transformer of the EP-IND-ZY, which heavy industrial sites actually need.

FAQ

Which industries is the EP-IND-ZY UPS intended for?

The oil and gas industry, oil refining, chemicals and industrial power engineering. It is a transformer-type UPS rated 10–120 kVA.

What does 3:1 mean in a UPS designation?

Three phases at the input and one phase at the output. The input voltage of the EP-IND-ZY is 300–500 V AC.

Why does an industrial UPS need a 12-pulse rectifier?

It reduces the harmonics the UPS injects into the input network, compared with simpler circuits. The EP-IND-ZY has exactly a 12-pulse rectifier.

What ingress protection does the EP-IND-ZY have?

IP31. The cabinet is installed indoors.

Which UPS should I take if I need a three-phase output?

For example, the UD rated 10–80 kVA with the 3:3 scheme. The EP-IND-ZY has a single-phase output.
