| Interactive voltage regulation in addition to battery back-up. |

Liebert PowerSure PSA - a line interactive UPS with automatic voltage regulation (AVR) that saves battery life while offering full-featured power protection for sensitive electronic equipment. Instead of switching immediately to battery power when utility voltage drops below or rises above 120, the PSA corrects that fault to provide powered equipment with the designed level of electric power. Then, if utility voltage moves outside of regulation range the PSA switches to battery to maintain power for orderly file storage and system shutdown.
Great against low voltage "sags", the Interactive Series contains a circuit that corrects input voltage as low as 90 volts and as high as 147 volts. Below 90 volts the UPS switches to battery power. This UPS also filters spikes, noise and other transients. It provides a minimum of 5 minutes of battery power and much more under a partial load. It is available in a floor case chassis and features user replaceable batteries.
Ideally suited for: professional PC's and workstations, small routers, bridges, and hubs.
