Charge Controls & Electronic Remote Sensing
The Auto Charge 1200 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. During this brief interval the Auto Charge 1200 measures and stores
the battery voltage. This battery voltage is compared to a standard and any error is
detected and used to control the charger output at the desired level. Their is no
“trickle charge” and therefore no danger of overcharging and water boil-off.
INTRODUCTION
The AUTO CHARGE 1200 is a compact, completely automatic, single channel
battery charger designed for vehicles with a single battery system. The charger is
ruggedized to withstand the shock and vibration encountered by vehicle mounted
equipment.
The battery charger features:
• Electronic remote sensing of true battery voltage, eliminates the need
for sensing wires
• Automatic current limiting
• Battery charge/condition indicator
• Power “ON” LED indicator

Automatic Current Limiting
When batteries are severely discharged, some battery chargers can be overloaded
due to the high charging current required. The Auto Charge 1200 contains an
automaticcurrentlimit. Thiscircuitlimitstheoutputcurrenttotherated40amperes
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.
Battery Charge Condition Indicator
This indicator shows the charge condition of the battery in 10 levels from “LOW
CHARGE” to “FULLY CHARGED”. This device indicates a defective battery when
a bar graph does not rise to the “FULLY CHARGED” level after an extended period
of charging.
NOTE: If a battery is being charged with an external load of 4 to 10 amperes
across it’s terminals, the bar graph may move down 1 or 2 levels. This
does not indicate a defective battery.
