2. General Information
2.1 Outline
The Imperial Series are advanced line-interactive simulated sine wave uninterruptible power
systems (UPS) 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 and
conditions the power continuously. When AC power fails, the unit employs its internal
maintenance-free battery to supply back-up power without interruption.
2.2 Features
Frequency Auto Sensing: The Imperial series UPS can operate in either a 50 or 60 Hz
environment. When you plug the UPS into an AC outlet and turn it on, it will automatically detect
the incoming line frequency and configure itself to match that frequency.
Smart Buck and Boost Line Conditioning:The voltage from your AC power source can fluctuate
above and below the standard rating. This microprocessor controlled UPS provides line conditioning
via both buck (step-down voltage) and boost (step-up voltage) functions. For example, if your
normal voltage is 120V and the voltage fluctuates up to 131V, the buck function in your UPS will
step it down so that your equipment receives approximately 120V. If the voltage fluctuates down to
109V, the boost function will step it up so that your equipment receives approximately 120V. This
provides your equipment with excellent voltage regulation with less possibility for the UPS to drain
its internal battery.
User Replaceable Battery Design:The battery is the most critical part in a UPS. The average
lifetime of a battery is between 3 and 5 years. The special user-replaceable battery design of this
