having tried endless attempts at getting the comupter buff to give me a sensible answer on how much heat a 10KVa UPS gives out, i have given up. (last answer 10,000 kW's:D ) he got upset when i said 10mW load would melt more than his hard drives.:eek:

Anyone got any idea's how much these babies produce in the way of sensible load. they are spanking new 3 phase and there are two, but that's as much as i know.

i'm not familiar with this...but i asked someone and he said it's about 0,8 kw.

i also want to know other answers.

Well, 10KVA = 10,000 VA or W so it's a 10kw UPS.

Now, dissipated heat should be the difference between the efficiency and the in-efficiency. So if it's 90% efficient the dissipated heat would be 10% or 1kw

Thanks Frank, you the Man.

Cruzeiros, which bit are you not familiar with? The UPS or the answer?

With all equipment operating at full load, measure power input at breaker box. One measurement gives the total heat output of all equipment.

I need to design and select the system before the equipment goes in as they will go 'live' within a day, and they need to a/c commissioned and live a few days before.
