Industrial UPS, Transformer-Based 1–800 kVA
Online double conversion with a full isolation transformer on the output, for heavy, inductive loads and hard grids.
The range
5 series, 1–800 kVA.
Why this range
A transformer-based (low-frequency) UPS adds a line-frequency isolation transformer after the inverter. It is heavier and a little less efficient than a high-frequency unit, but it gives galvanic isolation, a solid neutral and more headroom for motor inrush and short-circuit clearing.
These systems are built to project specification: voltage, frequency, rectifier pulse number, battery voltage and enclosure are agreed per order. They are not covered by our CE certificates.
