Compare the four series
The quickest way to narrow the range. Topology is usually the first decision: line-interactive is enough for equipment that tolerates a few milliseconds of break, online double-conversion is required where it is not.

Narrowing it down
Choose this if…

Aurora III
Choose this if you are protecting workstations, tills, routers or AV kit, and a 3–8ms break is acceptable.
View specifications

Infinity Series
Choose this if the load must never see a break, and you need pure sine wave with 0.9pf across 1KVA to 10KVA.
View specifications
Optima Series
Choose this if you need every nameplate VA as usable watts, adjustable charging, or the widest input window in the range.
