1. INTRODUCTION
1.1 Overview
The Value Series of Uninterruptible Power Systems (UPS) was designed to prevent
spikes, 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.
1.2 Frequency Auto Sensing
The VS models 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.
1.3 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 UPS provides
significant savings and gives the UPS an almost unlimited life. You can replace the battery
very easily, and without turning off your UPS or the equipment it is protecting.
Many UPS’s provide only a basic power failure warning. The Value Series, together with
OPTI-SAFE Xtreme also provides you with important operating information. If OPTI-SAFE
Xtreme is not part of your UPS package, you can purchase it from your local dealer.
