Where it fits

Applications and guides for this range.

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.

Application

Telecom

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.

Guide

Lithium-Ion vs Lead-Acid UPS Batteries: LiFePO4 or VRLA?

VRLA lead-acid is the low-cost, familiar choice for UPS backup. Lithium iron phosphate (LiFePO4) costs more up front but lasts longer, weighs less, takes heat better and needs fewer replacements. The right answer depends on runtime, room temperature and how long you keep the system.

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.
