C-Arm UPS

[Npstewart]

I have one piece of medical equipment, namely a C-ARM that needs to be backed up for a minimum of 2-hours. Any good manufacturers out there someone can suggest? The load is very small, 16A @ 120V. Unit plugs in with a standard cord.

Tripp Lite makes Hospital grade UPS boxes that would fit the application.

If the equipment is in a hospital and has a hospital grade plug connection, you will have to provide a hospital grade UPS.

thanks! Looks like this will work.

I was thinking about using the following UPS for this application:

The problem is that I wanted to install this in a closet, but the C-arm has a standard cord and plug and is supposed to plug directly into this UPS. Obviously I couldn't use a extension cord from the UPS to the machine, any ideas?

It probably needs free air circulation, even with its cooling fans.
0.03x16x120 = 58w, about as much heat as a 60w bulb puts out but it's only 97% efficient at full load.

Make sure that the heat removal(HVAC) for both the UPS and teh served equipment is also backed up by emergency power, othervise these suckers overheat and shut down. @ 2 hours you're looking at masses of batteries. Batteries ARE your weakest point, so I like larger, high MTBF UPS's with battery monitoring system. CellWatch or equivalent, not the ones integral to the UPS which monitors the whole bank, not the individual cells. Minimize battery run time and switch over to the standby generator as the bypass or secondary input source.

It's going to be a car sized battery bank. 4kWh available to load at 2kW. If UPS is 80% efficient on battery battery has to provide 2.5kW for two hours and since lead acid batteries are rated at 20hr rate, (meaning that 5Ah means it will supply 0.25A for 20 hrs, but if you load it at 5A, it won't last anything close to an hour) they have to be huge. Doubly huge, because you said 2 hours is the minimum.
