SURT10000XLI - power consumption is needed for battery charge

[Anonymous user]

Hi Everyone,

I've tried Google or product documentation, forum but cannot find. Please help to answer:

- Can i know how much consumption is needed for battery charge without device?

Reason: Beside device load, i also need calculate that value to request building management provide suitalbe power source, circuit breaker, electric wire condition as well.

Appreciate any help.

This UPS has an 800W battery charger it appears. So if the UPS is charging fully discharged batteries, it'd use the 800W charger and then as it gets close to 100% charge, start to trickle charge. Also, the documentation says it has 92% efficiency.

The recommended breaker size for the UPS should take all of this into account and also for a potential overload sizing I think.

Hi Angela,

Thank you for helpful answer.

Could you share:

- document related with "800W battery charger" and "92% efficiency"?

- the current (amps) for this battery charger (My guess is 3 amps)?

Please forgive for my annoying...

Hi Dzung,

I just realized I mis-read the model number you provided me. I looked up SRT10000XLI, not SURT10000XLI. SRT is the newer generation of the model you have. Though, the answers should be similar...

You can find the efficiency and a little graph listed here for your model: http://www.apc.com/resource/include/techspec_index.cfm?base_sku=SURT10000XLI 

I also only have an internal specification document telling me that the Maximum Input Current is 68A during 160V Bypass with battery charging. But I did confirm SURT10000XLI also contains an 800W charger, and Charging current (Amps) is listed as ~2 Amps.

I hope this helps. If you need a more formal document/specification sheet, I'd have to suggest you contact your local technical support office to see what they can provide.

It's great!

And the last...

Could you tell me about power consumption of UPS itself in operation?

Hi Dzung,

We have a tool call the UPS Efficieny Calculator. What it will do is tell you the UPS losses at any load. In the screenshot below, I've dropped the load down to 0 (and mind you, I am comparing the UPS to itself) and you can see it says the losses are about 185 Watts so that would be the answer to your question.

A link to this tool is here: http://www.apc.com/tool/?tt=5
