INTRODUCTION
The AUTO CHARGE 1200 PUMP PLUS 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 AUTO CHARGE 1200 PUMP PLUS operates an 091-9 air compressor. With the selector switch in the AC position the compressor runs only when the AC power is applied. With the selector in the DC position the compressor will operate when the AC power is ON or OFF. In either position the compressor operates from the vehicle’s batteries, the charger automatically recharging the batteries as required.
The battery charger features:
•Electronic remote sensing of true battery voltage, eliminates the need for sensing wires
•Automatic current limiting
•Remote Battery charge/condition indicator
•Power “ON” LED indicator
Charge Controls & Electronic Remote Sensing
The Auto Charge 1200 Pump Plus 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 Pump Plus 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 to the desired level. There is no “trickle charge” and therefore no danger of overcharging and water boil-off.
Automatic Current Limiting
When batteries are severely discharged, some batteries can be overloaded due to the high charging current required. The Auto Charge 1200 Pump Plus contains an automatic current limit. This circuit limits the output current to the rated 40 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.
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.
