5. CHARGE CONTROLLER OPTIONS
Next, ensure the unit is supplied with 120VAC at the input. Then, use Switch B to adjust the boost stage voltage by turning it slowly
with a small screwdriver while measuring the output voltage with a multimeter. When the desired voltage has been reached, turn switch
A back to the “3 Stage” position to put the charger back into its normal 3-stage charging mode. The charger may need to complete a
charge cycle before the new voltage will take effect.
4.4 REVERSE POLARITY FUSES
The GPC is protected against reverse polarity on the DC output. If a battery or the GPC is hooked up incorrectly, the fuses will blow and
can be easily replaced. Always use the same size and style fuse that came with the converter. To change the fuses, use a screwdriver
to loosen the screws and remove the fuses. Always replace the fuses with the same type and rating. After inserting the new fuses,
tighten the screws firmly. DO NOT OVERTIGHTEN.
5.1 GPC CHARGING
The optional GPC allows the GPC to operate as an automatic three-stage smart charger giving the customer the benefit of a Bulk, Ab
-
sorption, and Float stage charging. The charging capacity of the GPCis increased, charge times are decreased, proper and safe battery
charging is ensured, and overcharging is minimized.
Check with your batteries manufacturer specifications to confirm the GPC MAX charger will work.
5.1.1 REDUCED CHARGE TIMES
The Bulk stage allows the batteries to be charged from the full rated load of the battery. During this stage the batteries are recharged
quickly to reduce charge times.
5.1.2 INCREASED BATTERY CAPACITY
After the Bulk stage, the batteries are held in the Absorption stage for a controlled period, ensuring a full and complete charge.
5.1.3 REDUCED BATTERY STRESS
During the Float stage, the GPC charge voltage is reduced. This minimizes gassing while maintaining a full charge at the nominal rate
of the battery.
