600VA battery backup for PCs & retail point-of-sale application is a standby UPS that provides reliable battery backup & AC power protection against blackouts, brownouts, overvoltages, surges & line noise. 300-watt, 120-volt UPS protects home / office computing, networking & point-of-sale equipment in retail, kiosks, foodservice & light industrial environments. It's easy to set up in minutes. Just plug it into a properly grounded wall outlet. Press the power button & connect equipment to the UPS outlets. Input power cable, power button & status LEDs are on the same side for easy access. UPS switches to battery power to keep connected equipment running during short blackouts & brownouts, giving you enough time to save data & complete a safe shutdown in case of a longer outage. Incoming utility power keeps the replaceable VRLA battery fully charged so backup power is always available. It restarts automatically once power is restored.
