Introduction & System Description

Congratulations on your choice of the Liebert PowerSure™ Interactive Uninterruptible Power System (UPS). It provides conditioned power to microcomputers and other sensitive electronic equipment.

Upon generation, AC power is clean and stable. However, during transmission it may be subject to voltage sags, spikes, or complete power failure which may interrupt computer operations, cause data loss, or even damage equipment. The PowerSure™ Interactive protects equipment from these disturbances.

The PowerSure™ Interactive comes in nominal power ratings of 700, 1000, 1400, or 2200 VA. Complete specifications appear near the end of this section.

The PowerSure™ Interactive is a compact, “line interactive” UPS. A “line interactive” UPS continuously conditions and regulates its output voltage, whether the utility power is present or not. It supplies connected equipment with clean sinewave power, to simulate as much as possible, the power generated by the utility. Sensitive electronic equipment operates best from sinewave power.

For ease of use, the PowerSure™ Interactive contains a light emitting diode (LED) bar display to indicate “load percentage” or “battery capacity” depending upon the mode of operation. It also provides self diagnostics, a combination alarm silence/battery test button, and two levels of alarms when the unit is operating on battery.

The PowerSure™ Interactive has an interface port for communications between the UPS and a LAN server or other computer system. This port provides detailed operating information including voltages, currents, and alarm status to the host system when used in conjunction with Liebert SiteNet® software. SiteNet® software can also remotely control UPS operation.

CAUTION: This equipment has been tested and complies with limits for a Class A digital device, pursuant to Subpart B of Part 15 of FCC rules.
