The Powershield PSG1000 SafeGuard 1000VA Uninterruptible Power Supply (UPS) is designed for a home/office solution. Similar to but larger than the D 0873 model, this new model includes four battery backup and surge protected Australian sockets, another four dedicated surge-only protection outlets, USB charging and communications parts, plus an interactive LCD screen displaying relevant battery data. The unit provides simulated sinewave output and has an audible alarm when activated. It includes management software to suit most PC operating systems and can be wall mounted if required.
