How long will BR1500G last with VOIP modem

BillP · ‎2021-06-29

Hello, I'm trying to get an estimate on how long a UPS will power a VOIP phone/internet modem.

The modem is 9 W max, usually 6-7 W nominal. and usually about a .5 amp draw.

Any ideas on how long the BR1500G would last?

here is the runtime chart on that unit, on the middle of the page: http://www.apc.com/resource/include/techspec_index.cfm?base_sku=BR1000G

we don't test that low unfortunately so you can at least use 50 watts as a reference and expect a bit more out of the unit. with a load that low as well, the UPS won't be too efficient.
