Guide
What is a line interactive UPS?
A line interactive UPS feeds the load from the mains, corrects sags and surges with AVR and switches to battery within milliseconds during an outage.
ELSIPOWER line interactive models offer sine-wave output and 5 ms transfer. For servers, see our online UPS range.
- Automatic voltage regulation (AVR)
- Sine-wave output, 5 ms transfer
- Short-circuit, overload and deep discharge protection
- LED / LCD display, quiet operation

Selection
What size line interactive UPS do I need?
Add up the watts of your devices and choose a UPS whose watt rating is at least 20–30% higher.
For longer runtime or zero-transfer loads such as servers, choose an online UPS.
Example
- PC250 W
- Monitor40 W
- Modem + switch30 W
- Total + 30% margin≈ 420 W
- Suggested model1 kVA (600 W)

FAQ
Line interactive UPS FAQ
Line interactive vs online UPS?
Line interactive feeds from mains and switches in milliseconds; online UPS feeds through the inverter continuously with zero transfer time.
What does AVR do?
AVR corrects low or high mains voltage without using the battery, extending battery life.
How long does it run?
Runtime depends on load — longer at light load, a few minutes at full load.
Can it be used for a gas boiler?
Sine-wave models can power small motor loads such as boilers; check power and inrush first.
When should the battery be replaced?
Sealed batteries usually last 3–5 years; test them if runtime drops.
