The Sanyo Denki A11H On-line UPS is an excellent solution when sensitive equipment needs power protection. The wide input frequency range makes this UPS ideal for places that use backup generators, and the wide input voltage range allows the UPS to run longer without switching over completely to the battery, resulting in longer battery life. The optional LAN Interface card makes it easy to manage the A11H from a remote location, or the unit can be connected to a workstation or server with a serial connection.

However, as with most UPS systems available, there weren't any cable management options available with the unit, and there was a limited amount of space available for power adapters. The problem with power adapters may not be as much of an issue, since many of these units are powerful enough to protect multiple machines, and power distribution units or power strips can be used to divide the power to any necessary accessories. The main issues I had with the A11H were that it used a serial cable for connection to a single machine, and that setting up the optional LAN Interface card could have been easier with DHCP enabled by default.

Overall the Sanyo Denki A11H UPS is a quality piece of equipment with an excellent set of features.
