Where it fits
Applications and guides for this range.
Manufacturing
A half-second dip can stop a line, scrap a batch and reset every PLC. We size industrial and online UPS systems for controls, drives and process loads, not just the office IT room.
ApplicationOil, Gas and Petrochemical
Control systems, safety instrumentation and telemetry must stay powered through grid faults and generator changeovers. We build transformer-based UPS systems for the electrical and control rooms of process sites.
ApplicationPower Substations
Relays, SCADA, RTUs and communication equipment in a substation need clean AC power when station supply is disturbed. Our P-series power utility UPS is built for that control-room duty.
GuideIndustrial Isolation Transformer UPS: When Galvanic Isolation Matters
An isolation transformer breaks the direct conductive path between mains and load. In an industrial uninterruptible power supply it lets you create a clean new neutral, block common-mode noise and ride out the earthing problems that high-frequency units pass straight through.
GuideTransformer-Based vs Transformerless Online UPS: How to Choose
Choose a transformer-based online UPS for motors, heavy inrush, poor or generator-fed supplies and sites that need galvanic isolation. Choose a transformerless high-frequency unit for IT, control and electronic loads where size and efficiency count for more.
Questions buyers ask
What do you need for a quotation?
Load in kVA or kW, input voltage and phases, output phases, the backup time you need and where the unit will be installed. If you are unsure, send what you know and we will ask for the rest.
Can the unit carry our brand?
Yes. Logo, front panel, packaging and manual can be supplied under your brand. Minimum quantities and lead times are on the OEM / ODM page.
