Major Components, Automatic Voltage Regulator

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.
