INTRODUCTION
The Auto Charge 1200 Remote 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.
FEATURES
I. AUTO CHARGE 1200 BATTERY CHARGER
• Electronic remote sensing of true battery voltage, eliminates the need for sensing wires
• Automatic current limiting
• LED status indicators
• Local and optional Remote Battery charge/condition indicator display
• NEW! Battery Selector Switch (Lead-Acid/AGM)
II. 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. Since there is no charging current there is also no voltage drop
between the charger and the battery. The Auto Charge 1200 thus 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 1200 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.
IV. LED STATUS INDICATORS
1. BATTERY CONNECTED: Indicates that a battery of proper polarity is connected to the charger
output terminals
2. FAN ON: Indicates that the fan is operating. Fan operates whenever output exceeds 10 amperes.
Fan turns off when output current decreases below 5 amperes
3. POWER: Indicates that AC voltage is present
