Where it fits
Applications and guides for this range.
Healthcare
Imaging systems, lab analyzers and hospital IT react badly to dips and outages. We size double-conversion online UPS systems for individual devices up to whole hospital wings.
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.
ApplicationSecurity and Surveillance
Cameras, recorders and door controllers are spread across many small sites, each on its own supply. We supply compact online UPS units that keep recording and doors working through outages.
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 is the difference between the standard and the E model?
The standard model has batteries inside the tower. The E (long-run) model has a stronger charger and connects to an external battery cabinet for longer backup time.
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 it run on a 60 Hz grid?
Yes. The unit accepts 44–56 Hz on 50 Hz systems and 54–66 Hz on 60 Hz systems, and its output voltage is selectable from 208 to 240 VAC.
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.
