I am not that of an electricity knowledgable person, so I'll try to put as much info as possible.
I have a Rack Mount UPS of 1800 Watts Model: PRP 3050 RM (in total I have 2 of these - talking about one specifically)
I had to change it's batteries today, and that led me to think if it can support the hardware that are connected to it.
*I will add the specs I was able to find on each manufacturer site with links to PDF's Currently connected to it are:
- Netgear 1100 specs out of production
- QNAP U-859 RP+ specs *no amps indication
- Dell R610 spec
- Dell 1950 spec
- Dell 2850 spec
- Screen L1710S *minimal screen watts - < 0.5A
I have created on Dell's Power calculator ESSA, a map of the hardware I have:
- Total AMPS used is 5.8
- All three Dell's each have a redundant PSU
- according to Dell's site - that means that each PSU uses half of the said/needed Watt's.
- Each Dell is connected to 2 UPS's (both are PRP 3050 )
- My UPS's specs says it has a 8.5Ah - does that mean I can connect more appliances until I reach the MAX?
- What can I learn from this information that I have provided?
