INTRODUCTION
The Pump Plus 1200 is a compact, completely automatic, 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. PUMP PLUS 1200 BATTERY CHARGER
• Electronic remote sensing of true battery voltage, eliminates the need for sensing wires
• Automatic current limiting
• Remote Battery charge/condition indicator display
•
LED status indicators
•
Pump output with AC or DC mode rocker switch
• NEW!
Battery Selector Switch allows for Lead-Acid or AGM modes
II. CHARGE CONTROLS & ELECTRONIC REMOTE SENSING
The Pump Plus 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 Pump Plus 1200 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 Pump Plus 1200 contains an automatic current limit. The current
limit feature limits the output current to 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. PUMP OUTPUT
The output terminal strip provides an additional output to accomodate the Auto Pump 12V, Part
Number 091-9-12V. The Auto Pump output works in conjunction with a front panel mounted rocker
switch. For normal operation, the rocker switch should be left in AC mode, which means that the Auto
Pump works only when shoreline power is supplied to the charger. With the switch in DC mode the
compressor will operate when AC power is ON or OFF. In either position the compressor operates
from the vehicle’s batteries, while the charger automatically recharges the batteries as required.
