Did a rough measurement this morning of the current drawn by the EXES racks as various items were turned on.
Bottom line: Lots of headroom on the 2kVA UPS supply.
System draws about 6.5A total (absent the cal source supplies), which would be ~0.78kVA if we just multiply by 120V.
Here's a rough listing:
PC Host computer: 2A (momentary 4A on startup)
eBox supply: 2A
macmini + monitor: 1A
Lakeshore: 0.5A
Pot power supply + agilent + motor boxes + network switch < 0.5A total
The resolution on the current meter was only 0.5A, so these numbers are not precise below that level. Hard to see where we'll have a problem that would require us to use any of the non-UPS power.
