Pros:Plenty of backup power, good surge protection and voltage regulation, easy to maintain, well-designed interface.

Cons:Nothing significant found so far.

The Bottom Line: Highly recommended for home office and small business users who need good power and voltage regulation. Easy to use, great surge protection, all in a slim package.


This review is nearly identical to my review of the APC Back-UPS XS 1200 because these models are identical except for the added ethernet protection of the RS 1200. I purchased an XS 1200 for my digital darkroom at home, and then discovered that we use an RS 1200 at my work office. After spending a few weeks with the RS model, it appears that its performance is identical to that of the XS model, as far as I can actually observe. Accordingly, I've come to the same conclusions about the RS model.

Our RS 1200 is being used to protect a small digital imaging station, which includes a PowerMac G5, slide scanner, flatbed scanner, printer, and small audio speakers. It also protects an ethernet connection that allows access to our network and the Internet.


The Back-UPS RS 1200 is also identified by its official model name as BR1200. It is identical to the APC Back-UPS XS 1200, except for one difference - the RS model provides Ethernet protection, whereas the XS model does not. As of summer 2006, The XS model was readily available in local electronic stores and the RS model was scarce. However, the RS model is fairly easy to find in online electronics stores. This model sells for approximately $160 at most retail stores, and slightly less in online stores. This model includes a $150,000 connected equipment warranty.

Out of the box, this Back-UPS is a piece of cake to use. APC advises charging the unit for at least 8 hours prior to use to make sure the battery is fully charged, but it is operational after about 30 minutes of charging. The RS 1200 can be positioned vertically using the included stand, or positioned horizontally on its side. Vertically, it is an attractive unit that occupies a space 6 inches wide by 15 inches deep. My depth measurement includes 2 inches for cord plugs in the rear; the actual unit measures only 13 inches deep. My width measurement includes the full width of the stand; the actual unit measures only 3.5 inches deep. Overall, this is fairly compact considering the capabilities of this model. At 22 pounds, it isn't light but that's the price to be paid for serious battery power. Since most of this weight is in the bottom of the unit, it is extremely stable when mounted vertically.

A large, recessed button on the top front panel easily turns the unit on or off, but not so easily that you need to worry about accidentally bumping it and shutting off everything. This has been a problem on some APC units in the past. Four large LED lights just above the power button show the status of the unit. The lower front panel is removable to allow access to the battery. Removing it is easy, and hooking up the battery is equally easy - just mate the connectors together and you're done. The power cord is well shielded and six feet long, which has been long enough to reach the outlets around my work area with some length left over. Unfortunately, the power cord does not have the 90 degree flat mount plug that I have come to love on some other APC units, but it is flexible enough to usually not get in the way.

The RS 1200 has all of its power and data outlets on the rear of the unit. This is less convenient than the outlets located on the top of many of the less expensive (and less capable) Back-UPS models. However, it looks much nicer because it reduces cord clutter and it is more difficult to accidentally bump a cord out of its outlet. If you need to swap cords frequently, consider a Back-UPS with top mounted outlets instead of rear mounted outlets for ease of use. Otherwise, the outlet spacing provided by the RS 1200 is every bit as good as any of the other currently available Back-UPS from APC. Six of the outlets provide battery backup power, and two of these have transformer block spacing. The remaining two outlets offer surge protection only, and both of these have transformer block spacing. These eight outlets provide for the majority of my digital darkroom equipment. The remaining equipment, which does not require battery backup, is surge protected by a separate unit. There are also two phone cord outlets, which together work to protect one phone line from surges (one phone cord runs into the unit from the wall, another runs out of the unit to a modem). Similarily, an ethernet port protects ethernet connections for a network, Internet connection, etc.

Power cords plug into the outlets with ease, making this rear outlet unit fairly easy to use when I do need to swap cords. Thankfully, the cords don't unplug too easily such that they fall out of the outlets. However, because the cords plug into the unit on their side (90 degrees from their usual vertical orientation), some of my transformer blocks aren't as stable in their outlets as I would like them to be. They do not creep out over time, but if I bump them lightly, they begin to fall out. This is not really an issue unless I'm moving the unit around when I'm rearranging my office. Otherwise, the side oriented outlets are great because they keep the cords from becoming tangled and allow for a lot of transformer blocks on a small unit.

The included PowerChute software is the "Personal Edition", so it has just the basics that are needed to manage this unit. This software is optional; the RS 1200 can function just fine without it. I installed mine to be able to have the unit automatically shut down my computer if I'm not at home during a power failure. Use of this software requires a USB cable (included) that connects the data port on the rear of the unit to a computer. From a pull-down menu in the program, I chose how many minutes of remaining battery power I was willing to accept before the shut down process began. Also in this software, the user can manage the over- and under-voltage range according to the sensitivity of the equipment that is being protected. A current status monitor lets you see the load placed on the Back-UPS in real-time, and estimates how minutes the battery can provide power for the current load. This is a great feature for estimating your power requirements. Overall, the software was very easy to install (with no hang-ups on Windows XP) and use.

So how well does it work? As I did with the XS 1200, I kicked the plug (on purpose) to find out just what RS 1200 can do. The unit immediately sensed the power loss from the AC source and switched to battery without interrupting any of the processes running on my PC. With a PowerMac G5 running digital imaging software and iTunes, the slide scanner powered on, and the small audio speakers turned up to half volume, the battery held out for approximately 25 minutes. As with the XS 1200, this is impressive, considering the cost of this unit along with its relatively small size and surge protection capabilities. Speaking of surge protection, hot spring days have brought lighting storms and power grid fluctuations to my town. Like the XS 1200, the RS 1200 hasn't flinched for an instant. Most of the time, it sits on my desk doing nothing, waiting for something to happen. When it does, it handles it as advertised and keeps my digital darkroom in good health.

Customer Support

In the past, my experience with APC customer support has been very good. When lightning destroyed two of my APC surge protectors, they promptly replaced them free of charge, as the warranty said they would. No questions asked. The customer service representative was friendly and efficient. I have not needed to use customer service for the RS 1200, nor have I with the numerous other APC products I have, but it's good to know that I can get a reasonably fast response if I have a problem.


American Power Conversion has crammed a lot of power and utility into a slim, easy-to-use package in the RS 1200. Although Back-UPS units can be had for less than $30 these days, these models will usually not provide more than a few minutes of battery power during a blackout, nor do they provide the quality of voltage regulation found in the RS 1200. The RS 1200 gives me half an hour of computer and lighting power, which is good piece of mind with today's questionable power reliability. Combined with solid surge protection, APC has a winning power solution here, especially for those living in areas with unstable power grids. If you don't need ethernet protection, I highly recommend the XS 1200, which offers the same performance but is easier to find and usually sells for a few dollars less.
