Application
Data 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.
ApplicationTelecom
Telecom and network sites run unattended, often on unstable rural supplies. We supply rack-mount, modular and lithium-ion online UPS systems that keep links up and report problems remotely.
GuideOnline vs Offline UPS: Double Conversion, Line-Interactive and Standby
Uninterruptible power supplies come in three basic designs. Offline and line-interactive units pass mains through and switch to battery when it fails. An online double-conversion unit rebuilds the output all the time, so the load never sees the grid.
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.
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.
