Line-interactive UPS includes an autotransformer (AVR) that regulates voltage continuously — correcting sags and surges without switching to battery. The battery only activates on a complete power failure or extreme voltage condition that falls outside the AVR's correction range.
This significantly extends battery life compared to standby UPS in environments with poor power quality, while providing much better protection than standby topology. The most common UPS topology for IT server rooms, network closets, and commercial critical equipment.

Available from 550VA to 3kVA in single-phase tower form. Provides ±8% voltage window correction without switching to battery. USB and RS-232 communications for graceful shutdown software. Common in IT closets and small server rooms.
Available from 750VA to 3kVA (5PX) and 1.5kVA to 3kVA (5PX EX with extended battery option). Available in 1U rackmount and tower configurations. Excellent for dense rack environments requiring proven line-interactive protection.
Various single-phase models from 700VA to 10kVA. Robust construction designed for harsh industrial and commercial environments where standard commercial-grade UPS products may not survive.
Available from 500VA to 3kVA in tower configuration. Competitive line-interactive option with broad outlet count and standard communications ports.
Available from 700VA to 3kVA. Both tower and rackmount form factors available. Provides reliable line-interactive protection for server rooms on a competitive budget.
Available from 700VA to 3kVA in 1U and 2U rackmount configurations. Purpose-built for 19" equipment racks with a compact form factor that maximizes available rack space.
Line-interactive UPS delivers a compelling combination of protection, battery longevity, and value that makes it the dominant topology for IT environments.
AVR handles most power disturbances without switching to battery — significantly extending battery service life compared to standby topology.
2–4ms transfer to battery — faster than standby and adequate for all server power supplies and active network equipment.
Continuously corrects ±15–20% voltage swings without battery involvement — protecting equipment from the most common power quality issues.
Significantly better protection than standby at a modest cost premium — the best value proposition in the UPS topology range for most IT applications.
Line-interactive UPS is the standard recommendation for server rooms, network equipment, and commercial critical loads.
ePower Network will match the right model, capacity, and form factor to your server room or network closet.
