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.
