1.2 Smart Buck and Boost Line Conditioning
The voltage from your AC power source can fluctuate above and below the normal rated
input voltage. This microprocessor controlled UPS provides line conditioning via both
buck (
step-down voltage
) and boost (
step-up voltage
) functions. For example, if the
voltage fluctuates up by 15V, the buck function in your UPS steps it back down so that
your equipment receives the normal rated voltage. If the voltage fluctuates down by 15V,
the boost function automatically steps it back up. This provides your equipment with
excellent voltage regulation and less possibility for the UPS to drain its battery.
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 (

Chapter 6
).
