81 C Daily Kilowatt usage

[poopus]

We have a 3 stack, 11 module 81 C. Does anyone have an idea what the daily kilowatt hours the 81c would use in a normal 24 hour period. Just a ball park is what I am looking for.

Thanks

Is it an AC or DC switch?

It is an AC System.

I just searched the planning and engineering book for Kilowatt, no references. Only wattage references. Lots of variables on this. What type of modules, what type of cards, and on and on. If you can get your hands on the Planning and Engineering book you will find most if not all of your answers on power requirements.

I have looked at the power requirements. I did a quick calculation but seems a little hiigh to me. I think our UPS is capable of logging the actual usage but have not been able to locate the manual. (The UPS is managed by an IT counterpart who is off this week). I will just have to wait for his return.

Thanks

Generally, each Meridian 1 column will consume 1-2KVA.

So my UPS output for a 2 column 61c AC system is

True Power (Watts) 2144.00
Apparent Power (VA) 2673.00
Power Factor 0.80
UPS Load (%) 58


2144 / 2 columns is 1072 watts per column
1072 * 24 hours is 25728 watt hours per 24 hour period
25.728 Kwh per 24 hour period per column
My two column switch would be 51.456 per 24 hours
(commercial power in my area is .05606 per KWH - so it costs just under $3.00 per day not including Air Conditioning Costs)

for your 3 column switch it would be approx 77.184 kwh per 24 period. You could round it up and figure 100 kwh per day for your three columns total.

I think...I could be wrong...
