MANUAL MODEL: NC25A-12(24, 36, 48) Ultra High Efficiency 25 Ampere Alternative Energy Battery Charge Controller For GEL, AGM, and Flooded Cell Lead Acid Batteries 12V Controller Shown Below Patented SES Flexcharge USA, 1217 State St., Charlevoix, MI 49720 Ph: 231-547-9430, Web Site: www.flexcharge.
IMPORTANT INFORMATION THE NC25 CONTROLLER IS AN "ON/OFF" REGULATOR NOT A CONSTANT VOLTAGE REGULATOR, AND THEREFORE IT CANNOT BE TESTED BY SIMPLY MEASURING THE OUTPUT VOLTAGE ON THE TERMINAL STRIP OF THE CONTROLLER. THE CONTROLLER MUST BE CONNECTED AS SHOWN IN ONE OF THE SCHEMATICS BEFORE IT WILL REGULATE. READ ALL OF PAGES 5 through 8 OF THIS MANUAL TO LEARN HOW THE CONTROLLER REGULATES BEFORE CONCLUDING THAT YOUR CONTROLLER IS NOT REGULATING.
Features * 5 YEAR WARRANTY. * COMPLETELY SEALED ELECTRONICS FOR MARINE OR OUTDOOR MOUNTING. * LOW BATTERY VOLTAGE INDICATOR. (FLASHING RED LIGHT). * Works with GEL, AGM, and Flooded Cell Lead Acid Batteries. Also for flooded Ni-Cad Batteries * ARC REDUCTION CIRCUITRY TO ELIMINATE OR REDUCE RELAY CONTACT WEAR. * CHARGING EFFICIENCY BETTER THAN 99.50% FROM 0.5A TO 30A OF CHARGING CURRENT. * OPERATES EFFICIENTLY (98%) WITH AS LITTLE AS 0.1A OF SOLAR PANEL CHARGING CURRENT.
Peak Charge Voltage Adjustment Factory Calibrated for use with Lead acid and Gel and AGM Battery Technologies. Look for the small calibration dent in the case Multi Function Indicator System Voltage See the table on page 7 for description of operation 12= 12V, 24=24V, 36=36V, etc Call Direct to the Manufacturer.

INSTALLATION INSTRUCTIONS FlexchargeTM USA NC25A ULTRA HIGH EFFICIENCY CHARGE CONTROLLER Congratulations, you will soon be using the most efficient controller available. Using this controller has the direct equivalency of increasing your solar panel capacity by up to 20% over TM any other controller Flexcharge USA has examined. This controller is available with capacities to 2000 amps with the same, or increased charging efficiencies. NOTE: The NC25A does not contain any blocking diodes.
) 7) Connect the charging source (Solar, Wind, etc.) positive wire to the controller's INPUT+ terminal. CAUTION: IF THE SOLAR PANELS ARE EXPOSED TO LIGHT, THEY WILL BE GENERATING POWER. WIND SYSTEMS SPINNING UNCONNECTED CAN HAVE VOLTAGES ABOVE 100V. It is preferred to stop the generator from turning before connecting the wires from it.
a) Connect an accurate digital voltmeter on the terminals of the battery you are charging. b) If you are only checking the unit, skip this step, and step "d". Turn the adjustment most of the way towards "+". The dot in the case near the adjustment is the factory setting of 2.375V per cell. Continued c) Watch the voltmeter for the highest voltage you wish the batteries to charge to. d) SLOWLY turn the adjustment towards "- " until the DIVERT indicator comes ON (steady red or orange).
TM The Flexcharge Energy State Taper Charge Method The Energy State Taper Charge Process monitors the battery for the full charged resting voltage of the cells. There are tremendous advantages to this charge method. * Zero overcharging * Exceptionally low gassing (Up to 90% less) * Non-Destructive Micro-Equalization at each full charge * The battery’s chemical processes actually control the charging. * No RFI or EMI emissions to interfere with radio equipment.
