Dwayne, It's weird your client asked for such device since most of the computers are supplied with non interruptible power supply (UPS), which have also the over voltage protection built in. Such devices are cheap because the computers switching power supplies works OK in DC mode, so you don't nee true sinusoidal output UPS.
