Max Wattage for BR1500G Back-ups

This question was originally posted by John Michael on APC forums on 2/4/2015


Hey guys,

Just a quick question. I have a BR1500G which is rated at 865 Watts. My question is: Does the 865W max only apply to the 5 battery backup-surge protection outlets or does it apply to all of the outlets. 

In other words theoretically if I have 300 watts worth of equipment plugged into the battery backup outlets-surge protection outlets and 1000 watts plugged into the surge protection only outlets will this overload the machine?

Thanks for the help 🙂

JM

Hi,

The maximum output of the battery-surge outlets is 865 watts. The units breaker is rated at 12 amps for the combined load. In you example the load would be 10.83 amps so the unit can handle it but it is very close to the tripping point.

Bill, Thank you for the reply! This makes total since now and I see how you got the 10.83 amps.


Thanks!

Hi,

Thanks. I should have included the formula used to find the amps.

Amps = Watts / Volts

Assuming the input voltage is 120

1300 watts / 120 volts  = 10.8333333

That's interesting... we have some BackUPS 650s (BE650G1), and we specifically tested it to see how much total current could pass through the unit... the battery side would trip at about 525 watts, yet the unit could pass just about up to 15 amps, before tripping (before the panel breaker would trip).
