APC Line Interactive UPS

apc.estorewale has Best Line Interactive UPS in India, APC Line Interactive UPS typically incorporate an Automatic Voltage Regulator. The AVR allows the UPS to effectively step up or step down the incoming line voltage without switching to battery power. Advantage of Line-interactive UPS is it reduces the number of transfers to the battery. So the lifetime of the batteries is extended. Protect secondary electronics from surges and spikes without reducing battery power used to run primary electronics during an outage by using APC line-interactive UPS.

How long will an APC line-interactive UPS run?

It depends on two things: the size of the battery and how many watts you connect. A standard internal battery gives minutes to a few hours, not a full day. A light load like a router runs for hours. A desktop PC runs for tens of minutes.

These are estimates for a new battery at room temperature. Heat and an ageing battery reduce them. Check how many Ah the model you choose has on its product page.

Need 2 hours or 4 hours of backup for a computer?

A standard internal battery will not do it. For a desktop PC and monitor drawing about 120 W, you need roughly this much 12V battery capacity (before a real-world safety margin of about 20%):

• 1 hour: about 13 Ah
• 2 hours: about 27 Ah
• 4 hours: about 53 Ah

That is far more than the 7–9 Ah inside a typical Back-UPS. Your options are a model that supports an external battery pack, a higher-capacity UPS, or a UPS for the computer paired with an inverter for the rest of the house. Use the UPS runtime calculator for your own load, or read how many hours of backup you need.
