1.3 Theory of Operation

This high-performance, line-interactive, uninterruptible power source provides clean, reliable, AC

power to computer systems — protecting them from power blackouts, brownouts, swells, sags,

surges, and interference.

Normally, the unit operates “on-line,” supplying power from the utility input to the load (worksta-

tion, server, or other device). The converter circuitry is used to maintain an optimal float charge

level on the battery.

When the utility fails, the converter supplies AC power to the load and the disconnect switch opens.

The loads operate normally until shut down or until the battery is exhausted. The unit automatically

transfers the load back to utility power when the line voltage returns to normal.

The unit also provides surge protection and EMI/RFI filtering, as well as Smart-Boost

™

and

SmartTrim

™

, which correct high and low input voltage without drawing power from the battery.

Output control uses the unit’s remote interface to turn the load on or off, without disabling other

unit functions.

1.4 Features

Intelligent Battery Management

The unit provides visual and audible indications of the battery’s present status including capacity,

low battery condition, and replace battery condition.

The unit exercises the battery during its self-test, and detects a weak battery before it is put into ser-

vice. The unit normally performs a self-test at power up and every 14 days. Self-tests can also be

conducted manually with the on/test button at any time.

The unit features user-replaceable batteries. Batteries can be replaced without having to remove

power from the loads or send the unit in for service.

Computer Interface and Accessory Slot

Advanced monitoring, power management, and customizing functions are available through the

computer interface and accessory slot. See section 7 for more information.
