Long press is used to restore default settings. IN/OUT: Short Press to switch display input voltage or output voltage. Long press is used to switch display output current or output power. CV Potentiometer: Adjust output voltage. Increase the output voltage when rotating clockwise. CC Potentiometer: Adjust output current. Increase the output current when rotating clockwise. OUT LED: Green LED, Output indicator. It will turn ON when there is a output at output terminal. CC LED: Red LED, Constant current output indicator. It enters the constant current state when the load current reaches the set current and CC constant current indicator turns ON.  Usage: As an ordinary step down power module: Connect right input voltage at input terminal. Adjust CV constant voltage potentiometer to set output voltage according to require. Rotate CC potentiometer counterclockwise more than 10 turns at first. Test Output short circuit current by multimeter at 10A or 20A(Connect two Test Probes to output terminal on module) Rotate CC constant current potentiometer clockwise to set output current according to require overcurrent protection value. Test and using(e.g: Module’s maximum output current is 2A if display 2A on multimeter. Red LED indicator will turn on if output reach to 2A. Otherwise LED is OFF.)  As a charger: Tops: Power module can't be used as charger module if it does not support constant current function. The voltage difference between the battery with insufficient voltage and the charger is very large. Causes excessive charging current even damage the battery. So it need keep charging in constant current mode to reaching a certain level. Then automatically switch back to constant voltage charging. Make sure floating charge voltage and charge current for battery. If the lithium battery’s parameter is 3.7V/2200mAh, then the float charge voltage is 4.2V, and the maximum charging current is 1C, which is 2200mA. Connect right input voltage at input terminal.(Note: Please don’t connect load during set parameter) Test output voltage by multimeter and adjust CC potentiometer to make sure output voltage reach to require floating charge voltage. (If charge a 3.7V lithium battery, adjust the output voltage to 4.2V) Rotate CC potentiometer counterclockwise more than 10 turns at first. Test Output short circuit current by multimeter at 10A or 20A(Connect two Test Probes to output terminal on module) Rotate CC constant current potentiometer clockwise to set output current according to require charge current value. Connect battery at output terminal and start to charge.  As a high power LED constant current driver: Make sure LED working current and maximum working voltage. Connect right input voltage at input terminal.(Note: Please don't connect load during set parameter). Test output voltage by multimeter at output terminal and adjust CV potentiometer to set output voltage to LED's maximum working voltage. Rotate CC potentiometer counterclockwise more than 10 turns. Test Output short circuit current by multimeter at 10A or 20A(Connect two Test Probes to output terminal on module) Rotate CC constant current potentiometer clockwise to set output current according to require LED working current. Connect LED and test.  Note: Default output voltage and current is about 18V 7A. It is a step down power supply module, so the output voltage must be lower than input voltage. Otherwise it will not working normally. Please rotate the CV potentiometer counterclockwise more than 20 turns if there is no output voltage. It is a DC power module, so it can't connect to AC power. Please don't short output because 7A by default. Please set down output voltage less than 10V and rotate CC potentiometer counterclockwise more than 10 turns. And then short output to adjust output current. Input voltage must be 0.8V higher than output voltage. Please connect input before connect battery when use as charge and make sure output voltage is higher than battery voltage.  It is recommended to serial an anti-backflow diode at input positive terminal. "IN-" and "OUT-" can't be connect together, otherwise module can't support constant current output. Please make sure input power is more than load power. Please step down output power if module is hot. Please read use manual and description before use.  Application: Ordinary power supply Battery charger LED drive power Instrument voltage display Test meter Circuit test Power conversion   Package Included: 1 * ZK-JVA-12KX 12A Step Down Power Supply Module with Case
