INTRODUCTION

The Auto Charge Dual is a compact, completely automatic dual output battery charger designed spe

-

cifically for installations that require 24 volts for starting and 12 volts for accessories. The two batteries 

are connected in series to obtain 24 volts and the output of each charger is connected to each battery. 

Each output of the charger is individually controlled to charge it’s particular battery and is electrically 

isolated from the other. Two seperate ammeters indicate the output current to each battery.

FEATURES

I.  AUTO CHARGE DUAL BATTERY CHARGER

•  Electronic remote sensing of true battery voltage, eliminates the need for sensing wires 

•  Automatic current limiting 

• 

Automatically Charges Dual Banks of Batteries

•  Charges Both the 24 Volt & the 12 Volt Batteries Independently

• 

Designed Specifically for Vehicles with Dual Battery Systems

• 

Charging the 12 Volt Battery Does Not Effect the 24 Volt Battery

•  Front ammeter indicators

II.  CHARGE CONTROLS & ELECTRONIC REMOTE SENSING 

The Auto  Charge  Dual  contains  a  precision  voltage  controller  to  maintain  the  battery’s  charge.  

Automatic electronic remote sensing measures the true battery voltage, eliminating the need for the 

additional sense wires.  The output current of any charger is inherently a series of pulses whose 

frequency is determined by the power line frequency.  Therefore, there are brief intervals during 

which no charging current flows.  Since there is no charging current there is also no voltage drop 

between the charger and the battery.  The Auto Charge Dual measures and stores the true battery 

voltage.  This battery voltage is compared to a reference voltage, any error detected is then used to 

control the charger output at the desired level.  There is no “trickle charge” and therefore no danger 

of overcharging and water boil-off.

III.  AUTOMATIC CURRENT LIMITING

When batteries are severely discharged, some battery chargers can be overloaded due to the high 

charging current required.  The Auto Charge Dual contains an automatic current limit.  The current 

limit feature limits the output current to 20 amperes when charging a deeply discharged battery or 

if the starter cranks the engine while charging.  The current limiter thus eliminates the need for an 

ignition interlock circuit.
