BATTERY CHARGER APPLICATION – INSTRUCTIONS:
1. First determine the float voltage and charging current required by the battery to be charged (the ‘target battery’).
2. With the target battery disconnected from the module output, apply a voltage of 5V - 30V to the module input, being sure to observe correct polarity.
3. Using the CV trimmer, adjust the output voltage to about 5V. Switch your multimeter into its 10A current scale and measure the module’s short-circuit output current. Turn the CC trimmer to adjust the current to the charging current required by target battery.
4. Using the CV trimmer, adjust the module’s output voltage to the float voltage required by the target battery.
5. Connect the target battery to the module output, obser
