When the module output voltage can not be adjusted (the output voltage is always equal to the input voltage) Please adjust the potentiometer counterclockwise 20 laps (20 turns) or more till it works.￢ﾀﾋ 2. Turn trimmers CLOCKWISE to INCREASE, ANTICLOCKWISE to DECREASE. 3. When adjust the blue potentiometer,please use a multimeter to monitor the voltage 4. The trimmer nearest the voltage output adjusts the output CURRENT (CC) 5. The trimmer nearest the voltage input adjusts the output VOLTAGE (CV) Charger application - intructions: 1. First determine the float voltage and charging current required by the battery to be charged (the ‘target battery'). The target battery disconnected from the module output, apply a voltage of 7V - 32V to the module input, being sure to observe correct polarity. 2. Using the CV trimmer, adjust the output voltage to about 5V. 3. 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, observing correct polarity. Charging of the battery should commence ￢ﾀﾋ Constant current LED Driver Application - Instructions: 1.
