Normal Operation
During normal operation, incoming utility power is supplied to the load as shown
above. The utility power passes through the EMI/ RFI filters and TVSS circuitry
and then through the transfer switch to the connected loads. The battery charger
is operational whenever AC power is supplied, even when the unit is switched
off. PowerSure Personal continuously monitors the batteries.
Transfer Switch
In Normal mode the transfer switch passes utility AC power to the connected
load. When input utility or frequency is outside acceptable limits, the transfer
switch activates and transfers the UPS to battery.
Battery Charger
In normal operation, the battery charger converts utility AC power into regulated
DC power to float charge the battery.
Battery
The PowerSure Personal utilizes valve regulated, nonspillable, lead acid battery.
At typical room temperatures and with the UPS float charging, the battery system
will last many years.
Transient Voltage Surge Suppression (TVSS) & 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.
