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.
GuideWhat Is a Modular UPS? Frames, Hot-Swap Modules and N+X
A modular UPS is one cabinet holding several identical power modules that share the load, the bypass and the battery. You add modules as the load grows, carry a spare for resilience, and swap a failed module without taking the load off line.
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.
