INTRODUCTION
The Auto Charge D is a dual battery system automatic battery charger designed specifically for vehicles
with a DDEC control and a separate engine battery.
The engine battery on DDEC equipped vehicles presents a unique problem. While it is desirable to
have a charger to maintain this battery in a fully charged condition, this battery is relatively lightly loaded.
It is never required to operate any of the vehicle mounted accessories and is rarely discharged. The
vehicle, however, may have multiple batteries which may be heavily loaded and require considerable
charging. The unequal loading may cause either overcharging the engine battery or poor charger ca-
pacity utilization. The Auto Charge D specifically addresses this problem and automatically recharges
and maintains both vehicle and engine batteries.
FEATURES
I. AUTO CHARGE D BATTERY CHARGER
• Independent charge controls for each battery
• Electronic remote sensing of true battery voltages,eliminates the need for sensing wires
• Automatic current limiting for both engine and vehicle batteries
• Built-in 5 ampere Batery Saver
• Remote dual battery charge/condition indicator
• Power “ON” LED indicator
• Battery Saver overload indicator
II. CHARGE CONTROLS & ELECTRONIC REMOTE SENSING
The charger contains two independent charge controls, one for each battery. This allows each battery
to be independently charged while maintaining battery isolation. Each battery voltage is remotely
sensed, electronically, eliminating the need for four sense wires. Each of the charge controls is com-
pletely automatic and stops charging the battery when it is fully charged. There is no trickle charge
and therefore no danger of overcharging and water boil-off.
III. AUTOMATIC CURRENT LIMITING
The charger contains automatic current limiting for each output. The vehicle output is limited at 25
amperes while the engine output is limited at 3 amperes. This provides the higher current to the
larger batteries where it is needed.
