SUA1500I, power consuption?

[BillP]

I´m a reseller in Argentina, and a customer is asking me wich is the self consumption of the UPS SUA1500I. Thanks.
Soy un reseller en Argentina y un cliente me pregunta cual es el autoconsumo de la SUA1500I, es decir ademas de la carga conectada, que extra tendra por el autoconsumo de la UPS. Gracias!

Here is what I know:

Internal power consumption is the amount of power coming into the UPS that does not leave to support the load, and is due to internal conversion to either heat or stored battery charge. Internal power consumption is equal to the inefficiency times the Watt rating at full load.

Example: SURT5000XLI (full load) is rated at 3500 watts and 92% efficiency. The internal consumption is equal to 3500 watts * (100%-92%)=280 watts

As far as calculating the extra power consumption when the batteries are fully charging, you would add the charger watt rating (for this UPS is 136W) to the internal power consumption. However, calling this internal power consumption may not be theoretically correct since the energy is being stored for later use, not dissipated and lost. If it helps, this UPS's BTU rating is 135 BTU/hr.

Thank you Angela, and which is the efficiency of the SUA1500I?

[BillP]

I did some more digging.

If you go to tools.apc.com and refer to the fourth option down, UPS Efficiency Comparison Calculator, you can use the SUA750I's data as I don't have it for the SUA1500I. This would be for no load efficiency unless otherwise stated.

Thank you Angela. Now I can´t get into the doc because of a database maintainment. When I do it, I will tell you if it´s ok. Regards!

I can´t get into the info:

Wich is the SUA1500I efficiency? Thanks!

I just went to http://www.apc.com/tool/?tt=5 and here is the best I can give you for the closest UPS we have data on.
