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.
ApplicationData Centers
Data center power has to grow with the racks and stay up while you service it. We supply modular, rack-mount and lithium-ion online UPS systems from server room to full data hall.
GuideHow to Size an Online UPS: kVA, kW, Inrush and Battery Runtime
Sizing a UPS system is two jobs: choose a power rating that carries the load with margin, then a battery that carries it for long enough. Here is a method and a worked estimate; for a real project, ask us for a calculation.
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
Can two or more units run in parallel?
Yes. Up to four units can be paralleled for capacity or redundancy and can share one battery bank.
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.
Does it work with a diesel generator?
Yes. The wide input voltage and frequency window lets it ride through generator start-up and frequency drift without going to battery.
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.
