Power-Sonic PSC 12800A - Manual (Page 3)

GENERAL DESCRIPTION
This unit is a two stage, constant voltage battery charger with current limiting, current fold back, and
automatic temperature compensation of the output voltage. It is protected against shorting the out-
put terminals and reversing the output terminals on a battery. Various output cables are available.
There is one indicator light. It lights green to indicate when power is applied and, when a battery is
attached, that the charger is in float mode. It lights yellow when the unit is charging the battery. It
lights red to indicate a fault condition (shorted/reversed output connector).
This unit is designed to automatically switch into a single stage, float charge mode when the
battery is charged. A single stage, parallel charger version is available for keeping a battery
fully charged when used with a permanent or intermittent parallel load. This unit is not
designed to operate as a standalone power supply.
ASSEMBLY INSTRUCTIONS
Loosen the screws on the charger output terminal
strip. Identify the polarity of the terminal strip and
the output connector; both the charger housing
and the output cable are marked with “ + " & “ - “
symbols. Attach the two spade terminals to the
terminal strip and tighten the screws. To prevent
accidental shorting, cover the exposed terminals
with the molded press-on terminal cover.
OPERATING INSTRUCTIONS
Before using this battery charger, make sure it is compatible with your battery. Refer to the ratings on
the battery charger, the specifications in this manual, and your battery documentation. Charge only
sealed or valve regulated, lead-acid, non-automotive, maintenance free rechargeable batteries. At-
tempting to charge other types of batteries may result in battery damage.
Plug the power cord into a properly grounded outlet which supplies the correct input voltage. The in-
dicator light should now be on indicating that the charger is operating.
Determine the battery polarity. Most batteries identify the positive terminal with a “+" sign or the
color red and identify the negative terminal with a “-" sign or the color black. Connect the red insu-
lated output clip to the positive battery terminal and connect the black insulated output clip to the
negative battery terminal. If the charger is provided with a polarized connector, make sure your
battery plug is wired to match the output connector.
The charger should now be on and charging the battery. The indicator light should be yellow. The
yellow charge light will stay on until the battery is about 95% recharged. At this point the indicator
will turn green and the battery may be used. The battery should be left connected to the charger for
an additional three hours to ensure a 100% recharge. To ensure a full charge and to help your battery
keep its full capacity, we recommend that the battery be left connected to the charger, in float charge
mode, until ready to use. The battery may be left connected to the charger indefinitely, in float
charge mode, without danger of overcharging.
