1.1 Overview
The Enhanced Series of Uninterruptible Power Systems (
UPS
) was 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. When AC power is present, the UPS filters the power
continuously. When AC power fails, the unit employs its internal maintenance-free
battery to supply back-up power without interruption.
