NOTE : This charger is designed for vehicles with dual batteries and
negative ground.
INPUT :115 volt, 50/60 Hz, 3.5 amps
OUTPUT: 18 Introduction
The AUTO CHARGE 2000 is a compact, completely automatic, dual channel
battery charger designed for vehicles with two batteries. The charger is
ruggedized to withstand the shock and vibration encountered by vehicle
mounted equipment.
The battery charger features:
-
Independent charge controls for each battery
-
Electronic remote sensing of true battery voltages, eliminates
the need for sensing wires
-
Automatic current limiting and apportionment
-
Built-in BATTERY SAVER
-
Remote dual battery charge/condition indicator
-
Power “ON” LED indicator
-
BATTERY SAVER overload indicator
Description
Independent Charge Controls & Electronic Remote Sensing
The charger contains two independent charge controls, one for each battery.
This allows each battery to be independently charged while maintaining battery
isolation. Each battery voltage is remotely sensed, electronically,
eliminating the need for four sense wires. Each of the charge controls is
completely automatic and stops charging the battery when it is fully charged.
There is no trickle charge and therefore no danger of overcharging and water
boil-off.
Automatic Current Limiting & Apportionment
The charger contains automatic current limiting at 15 amperes. This is a total
current limit for the two batteries combined. The charger automatically
apportions the current to each battery. Either battery can draw the total 15
amperes. When charging unequally charged batteries, the lower charged battery
receives a higher charge rate. When the batteries are equal, the current is
shared equally until they are fully charged at which time the current goes to
zero.
Battery Saver & Indicator
A 3 ampere BATTERY SAVER is built into the charger. When connected as
shown in the installation wiring diagram, loads on battery #1 such as radios
and rechargeable hand lights are automatically switched to the BATTERY SAVER
when power is applied to the charger. The BATTERY SAVER allows more efficient
charging by removing these loads. A BATTERY SAVER overload indicator alerts
the operator that the BATTERY SAVER load has exceeded 3 amperes.
|
WHEN A BATTERY SAVER OVERLOAD OCCURS:
a. Remove the loads for approximately two minutes
b. Reduce the load to 3 amperes or less
c. Reapply the load to the BATTERY SAVER |
No fuses are required or provided as the BATTERY SAVER contains an electronic
overload interrupter.
Remote Dual Battery Charge Condition Indicator
This remote indicator shows the charge condition of each 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 1.5 to
4 amperes across it’s terminals, the bar graph may move down 1 or 2 levels.
This does not indicate a defective battery.
To avoid this, connect all external loads to the BATTERY SAVER terminals.
Loads connected to the BATTERY SAVER will be powered either from the BATTERY
SAVER power supply when the A.C. power is “ON”, or they will be connected to
battery #1 when the A.C. power is “OFF”.

CAUTION BATTERY SAVER
This battery saver output is a full wave rectified sine
wave. The 12.5 volts D.C. has a peak value of approximately 17.5 volts. It
is recommended that the loads are not highly capacitive. A large capacitor
on the load terminal will “peak detect” the output and create a voltage of
approximately 17 volts. This voltage may be too high for the component
connected. It is suggested that the installer check the output of the
battery saver (when operating with A.C. Input) and determine as each load
is connected that the voltage does not rise. Any load that creates an
increase in voltage should not be connected to the battery saver but
rather be connected directly to the battery. |
