APC PowerStack 450
The PowerStack 450 was the only 1RU UPS submitted for this review, and it is quite a nice unit given the limited space and the limited budget it falls within. This is a simple UPS with four female sockets and a serial port on the back. The display is limited to four individual LEDs for mains, battery, system overload, and replace battery.
The run time of just over 20 minutes was the shortest of all the units tested, but this is generally long enough to beat all but the worst of blackouts, and probably has room to grow. If this UPS was to be used in a network distribution cabinet, it would provide more than enough support for a number of devices, but the main shortcoming would be the lack of power outlets available. Hot swap batteries are a real bonus in this price range. The running cost score was an acceptable AU$36.37 per minute, which is fairly good for a low entry price unit.
The PowerChute Plus software is very simple to use, and provides at a glance all the information you really need, while underneath is an excellent level of customisation that is well designed and laid out.
