MAJOR COMPONENTS
TRANSIENT VOLTAGE SURGE SUPPRESSION (TVSS) AND EMI/RFI FILTERS
These UPS components provide surge protection and filter Electromagnetic
Interference (EMI) and Radio Frequency Interference (RFI). They minimize any
surges or interference present in the utility line and keep the sensitive equipment
protected.
AUTOMATIC VOLTAGE REGULATOR
In normal operation, the Automatic Voltage Regulator (AVR) passes utility AC
power to the connected load. When utility power voltage is outside acceptable
limits, the AVR activates. It raises undervoltage power and lowers overvoltage
power. This keeps the UPS output voltage within the connected equipment’s
tolerances and allows wide utility voltage fluctuations without utilizing battery
power.
BI-DIRECTIONAL CONVERTER
In normal operation, the bi-directional converter “converts” utility AC power into
regulated DC power to “float” charge the battery system. Upon a utility power
failure, the bi-directional converter receives its required energy from the battery and
“inverts” it into precise, regulated sinewave AC power. Charging takes place
whenever the UPS is plugged into the wall outlet whether it is ON or OFF and utility
power is within acceptable limits.
BATTERY
The PowerSure™ Interactive utilizes valve regulated, nonspillable, lead acid
batteries. At typical room temperatures and with the UPS float charging, the
battery system will last many years. For battery run times, refer to the Typical
Battery Discharge Curves.
