2. General Information 2.1 Outline The Imperial Series are advanced line-interactive simulated sine wave uninterruptible power systems (UPS) designed to prevent spikes, surges, sags, transients and blackouts from reaching your sensitive equipment. Your equipment may include such items as computers and computerized instruments to telecommunication systems. - Page 5 UPS provides significant savings and gives the UPS an almost unlimited life. You can replace the battery very easily, and without turning off your UPS or the equipment it is protecting. Advanced Interface to Communicate with Computer Many UPS’s provide only a basic power failure warning.
