The Eaton 5SC pure sine wave UPS provides high-quality output voltage for wider compatibility with today's active PFC (power factor corrected) power supplies in sensitive IT equipment. Ideal for small business, high-end workstations, servers, storage and network equipment, the 5SC UPS corrects a wide range of input voltage variations through continuous regulation without the use of batteries. The LCD interface provides clear status of key parameters and allows configuration for output voltage, the audible alarm and power input sensitivity. By paring the 5SC pure sine wave UPS with Eaton's Intelligent Power Protector software, you can avoid data loss by gracefully shutting down your connected computer during an extended power outage. The 5SC comes with a standard three-year warranty on the UPS and batteries along with a $150,000 load protection guarantee for all of your connected equipment. Applications include: High-end residential, retail, banks, offices, small business. Connected equipment may include: High-end desktop computers and workstations, gaming PCs, networking devices, kiosks, entertainment systems, point-of-sale (POS) equipment, network-attached storage (NAS), servers and other IT equipment. The UPS arrives with the internal batteries disconnected for safety during shipping. Please be sure to connect the internal batteries prior to startup for normal operation.
