J-6362/U 24 V DC CABLE W/NATO SLAVE CONNECTOR, PP-8444A/U. This state of the art 24 Volt DC power cable is connected to the 24 volt DC source via the NATO SLAVE connector in a vehicle (i.e. HMMWV) and a PP-8444 A/U battery charger. As a safety feature of the Universal Charger (PP-8444A/U), the input power selection is accomplished by two (2) electrically interlocked power ON/OFF panel switches which assure that only one (1) power source at a time (AC or DC) can be used to operate the charger.
