UPS by what it's protecting
Desks & single workstations
500–1500VA line-interactive units give enough runtime for a clean shutdown and ride out brownouts.
Network cabinets
Rack-mount 1–3kVA with network management cards for remote monitoring and scheduled shutdown.
Server rooms
Online double-conversion above 3kVA — zero transfer time and full waveform conditioning for sensitive kit.
Sizing a UPS
Quick guidance to help you choose the right specification with confidence.
Watts not VA
A 1500VA unit typically delivers around 900W. Size to 70–80% of the wattage so batteries aren't at their limit.
Topology
Line-interactive for most offices. Online double-conversion for sensitive equipment or poor mains.
Runtime
Most units give 5–10 minutes at full load — enough for graceful shutdown, not for riding out an outage.
Form factor
Tower for under desks and open floors. Rack-mount where cabinet U space allows.
Management
A network card gives SNMP monitoring and scheduled shutdown across multiple servers.
Batteries
Expect replacement every 3–5 years. Check the modules are user-serviceable.
If you need to stay up rather than shut down, you're sizing for extended packs or a generator.

About
Sizing and specifying uninterruptible power
Size on watts, not VA. Manufacturers headline the VA rating because it's the larger number, but the real constraint is the wattage your load draws. A 1500VA unit typically delivers around 900W, so size to 70–80% of that for headroom.
Line-interactive suits most office and small server-room loads: it corrects minor voltage sag and switches to battery in a few milliseconds. Online double-conversion runs everything through the inverter continuously, giving zero transfer time and full waveform conditioning — worth it for sensitive equipment or where the mains supply is genuinely poor.
Runtime is the easiest thing to under-specify. Most units give 5–10 minutes at full load, which is enough for a graceful shutdown but not for riding out an outage. If you need to stay up, you're sizing for extended battery packs or a generator.
UPS — common questions
How do I size a UPS correctly?
Size on watts rather than VA. A 1500VA unit typically delivers around 900W, and you should load it to no more than 70–80% of that so the batteries aren't working at their limit.
What is the difference between line-interactive and online UPS?
Line-interactive corrects minor voltage variation and switches to battery in a few milliseconds, which suits most offices. Online double-conversion runs power through the inverter continuously, giving zero transfer time and full conditioning for sensitive equipment.
How long will a UPS keep equipment running?
Most units provide 5–10 minutes at full load, designed for a graceful shutdown rather than riding out an outage. Extended battery packs are available where longer runtime is required.
