Hello

Unfortunately, there is no direct answer and depends on many factors.  Depending on the input voltage supply to the UPS, either 120VAC or 230VAC, at any time the UPS could be consuming input maximum of 1.4kVA [120V x 12I] OR 2.3kVA [230V x 10I].  However the input consumption also depends on how you have configured your UPS in relation to the Power-Saving Function, Power-Saving Display, Unit sensitivity etc.  Please see the user Installation and Operation manual page 3 via the following web link...

When your setup is complete with the UPS, I would recommend you connect the UPS into a watt meter and observe the power consumption.  This will give you some good approximation regarding the level of input power consumption by the UPS.

Hi! Thanks for the reply, can you give me a wild guess of what would be the lowest power consumption and the highest power consumption when I use it and when I don't use it?

Hi Chyril,

We can get a good idea from the tech specs here (under the tech spec tab):

http://www.apc.com/shop/us/en/products/APC-Power-Saving-Back-UPS-Pro-1500/P-BR1500G

It supports 865W and if you view the efficiency graph, 97.2% efficient at 25% load (216.25 W). So:

efficiency = output_power / input_power

=> input_power = output_power / efficiency

=> input_power = 216.25 W / 0.972 = 222.5 W

UPS_power = input_power - output_power

=> UPS_power = 222.5 W - 216.25 W = 6.25 W

So that's one answer... at light loads the UPS itself uses 6.25W which is 0.00625 kWh in an hour, or 0.15 kWh a day.

If you do the algebra out symbolically, you'll get:

=> UPS_power = output_power * (1-efficiency)/efficiency

So plugging in the numbers, we find the UPS uses 6.25W at 25% load and 15.9W at 100% load. So your range is 6.25W to 15.9W.
