E•P RAPID DESKTOP CHARGER
1. DESCRIPTION
The DCS StarTAC Desktop Charger is a dual pocket,
intelligent charger capable of charging batteries of different
technologies and capacities automatically. The charger reads
the charging parameters from any E•P compatible battery or
uses default charging values if a battery EPROM is not
detected.
A microcontroller inside of the charger controls the charging
current delivered to the rear pocket according to its stored
program and the values of the charging variables read from
the battery pack. The input voltage to the charger is provided
by the Rapid Charging Transformer which acts as a voltage
tracking power supply.
The front pocket of the charger is capable of powering a
StarTAC and its internal charger to allow charging of any
attached primary and/or auxiliary batteries. The rear pocket
can charge any stand alone StarTAC batteries.
