Frequently asked questions

VA or watts?

Both appear on a UPS. Watts is the real power it can supply, and it's the number to size against. Add up the watts of everything connected and choose a UPS rated comfortably above it.

How long will it run?

It depends on the load. Check the runtime chart on the listing. At half load, a typical 1500VA UPS might run for 10 to 20 minutes, which is enough for a clean shutdown rather than all-day running.

Line-interactive or online?

Line-interactive units suit most offices and comms rooms. Online (double-conversion) units give the cleanest power for sensitive or critical equipment, at a higher cost.

Can we buy on account?

Yes. A trade account gives access to trade pricing and credit accounts for approved businesses, with a named account manager for repeat orders.

Equipping a whole team?

A dedicated account manager for every trade account.
