This charger features user selectable 2 or 3 stage charging. The charging profile is selected by
moving the slide switch on the front panel left to 3 stage or right for 2 stage charging.
A two-stage charger provides a constant
current until the battery reaches its rated
capacity and then switches to a “float”
voltage. The current then reduces as neces-
sary to maintain the battery at the float
voltage. The charger can be connected to
the battery indefinitely and will provide the
appropriate profile. A two-stage charger is
recommended in most instances since it is
the most versatile and can be permanently
connected to attenuate the characteristic
discharge of unused batteries. A load can
be put on the battery or batteries without altering its ability to keep the battery at optimal
charge.
2 or 3 Stage Charging
54.4VDC. If you wish to adjust this voltage, first locate the output adjustment potentiometer
access hole next to the diagnostic LED’s on the front panel. Reach in with a very small flat
blade screwdriver to rotate the potentiometer. Clockwise increases the output voltage and
counter clockwise decreases it. When you are done, replace the cover plate and securely
tighten the screws.

A three-stage charger is the fastest charger.
It charges the battery at a constant current
until the battery voltage reaches a slightly
elevated level. The battery is maintained
at this voltage while the charging current
diminishes to a low value, and then the
battery is switched to the float voltage
where it can be maintained indefinitely.
However, the charger cannot differentiate
between a current going to a load on the
battery, or being absorbed by the battery, so
it can overcharge a battery supplying current to a load. A two-stage charger is preferred for
“loaded” batteries and a three-stage for idle or unloaded batteries during recharging.
All of Analytic Systems’ chargers include adjustable output voltage for charging standard
or deep cycle lead-acid, VLRA or gel type batteries.
