UPS for DIT Cart

[Nick Pasquariello]

Similar yet different from the Batteries for DIT cart thread . . .

We've finally got a Bigfoot cart in, and are about to start kitting it up. First priority, in my opinion, is to set it up with a 2U UPS (feel like a 4U or 5U would be taking up too much space. A 2U should provide us with enough time, in the event of power loss, to halt transfers and transcodes, and power down safely.)

I think we'd need something like this: http://www.bhphotovideo.com/c/product/805204-REG/APC_SMT2200RM2U_Smart_UPS_2200VA_RM_2U.html

We'll routinely be running a Mac Pro with Red Rocket card, 2 GRaids, Red Station 1.8", HP or Dell GUI monitor, and Flanders 17" broadcast spec monitor.

Is anyone using the above linked UPS? Is there anything else someone would recommend for a 2U solution? I'm inexperienced with adding up all the various power draws to figure out the needed Voltage/Wattage requirements. We may eventually add a Cache-A ProCache 5 to the mix, or a in-tower RAID setup, or both. Which may be too much for any 2U UPS to handle.

So what are people with carts using? Any other product/brand I should be looking at?

Nick That should be fine

I rune the 1500, this will just have more runtime. I would still recommend getting a Power conditioner in line before the UPS. You will kill the UPS's batteries if you are running on a generator. The UPS will use the batteries to supplement bad power.

The only thing with the 2200 is that you will have to cut and replace the power cord. It has the 20A version of the household power cord with one side horizonetal instead of vertical.

For this particular cart, I can almost guarantee that it will be used inside, on a set, every single time. So not running off a generator. Would we really need a power conditioner? I'll be honest: I'm not really clear on what a power conditioner does, or exactly why it's needed.

I would recommend getting one from the Extended Run series, which lets you add external battery packs later if you want to. You may think 5 minutes is plenty right now, just to halt everything and shutdown, but there may be a time in the future when you decide you need an hour capacity. Then it's an easy add-on to get a rack-mounted battery pack.

A power conditioner smooths out irregularities in the voltage and the frequency of AC power, which can damage sensitive electronics long-term. Maybe someone can give a more detailed answer than this. But anyway, most UPS units have that function built in. Why would you need to buy a separate conditioner?

I forgot to mention: Check out www.refurbups.com. They have name-brand refurbished units, with their own off-brand new batteries. I've heard some good things, so I just placed an order for myself. Time will tell if their batteries are any good.

Actually part of the reason to have the battery is so you don't have to halt everything and shut down while the electrical crew repatches you...
