ON/OFF: Short Press to select whether output voltage. Long press is used to restore default settings for next re-power. IN/OUT: Short Press to switch display input voltage or output voltage. Long press is used to switch display output current or output power. ’+’ Button: It is used to regulate output voltage. Increase output voltage. Each time the button is pressed for short press, the output voltage is increased by 0.05V.Long press can continuously increase. Increase 0.1V, 1V in continuous if keep long press again. ’ – ’ Button: It is used to regulate output voltage. Decrease output voltage. Each time the button is pressed for short press, the output voltage is decreased by 0.05V. Long press can continuously decrease. Decrease 0.1V, 1V in continuous if keep long press again. ADJ-I Potentiometer: Adjust output current. Increase the output current when rotating clockwise. Module enters constant current output state if load current reach the Set Current Value. Constant current Red LED indicator CC will turn ON. ON LED: Green LED. Output indicator. It will turn ON when there is a output at output terminal. Otherwise it is OFF. 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. FULL LED: Green LED. Charged fully indicator. When battery is charged fully. It will turn ON. It will turn ON if output current is less than 0.2A when the Set Current is 2A. CHAR LED: Charging indicator. It will turn ON when charging. Using as a ordinary step down power module… 1.Connect right input voltage at input terminal; 2.Adjust ’+’ and ’ – ’ constant voltage buttons to set output voltage according to require. 3.Rotate ADJ-I potentiometer counterclockwise more than 10 turns at first. 4.Test Output short circuit current by multimeter at 10A or 20A (Connect two Test Probes to output terminal on module) 5.Rotate ADJ-I constant current potentiometer clockwise to set output current according to require overcurrent protection value. 6.Test and using module’s maximum output current is 2A if display 2A on multimeter. Then the maximum current can only be 2A when use this module. Red LED indicator will turn on if output reach to 2A.Otherwise LED is OFF.) 7.The output voltage will decrease due to the current sampling resistor at the output. The higher the current, the more the voltage is reduced. As a charger: 1. Power module cannot 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. That causes excessive charging current even damage the battery. So it needs keep charging in constant current mode to reaching a certain level. Then automatically switch back to constant voltage charging. 2. Make sure floating charge voltage and charge current for battery. If the lithium batteries parameter is 3.7V/2200mAh, then the float charge voltage is 4.2V, and the maximum charging current is 1C, which is 2200mA. 3.Connect right input voltage at input terminal.(Note: Please don’t connect load during set parameter). 4.Test output voltage by multimeter and adjust ’+’ and ’ – ’ constant voltage buttons 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) 5.Rotate ADJ-I potentiometer counterclockwise more than 10 turns at first. 6.Test Output short circuit current by multimeter at 10A or 20A(Connect two Test Probes to output terminal on module) 7.Rotate ADJ-I constant current potentiometer clockwise to set output current according to require charge current value. 8.Connect battery at output terminal and start to charging. As a high power LED constant current driver: 1.Make sure LED’s working current and maximum working voltage. 2.Connect right input voltage at input terminal.(Note: Please don’t connect load during set parameter). 3.Test output voltage by multimeter at output terminal and adjust ’+’ and ’ – ’ buttons to set output voltage to LED’s maximum working voltage. 4.Rotate ADJ-I potentiometer counterclockwise more than 10 turns. 5.Test Output short circuit current by multimeter at 10A or 20A(Connect two Test Probes to output terminal on module) 6.Rotate ADJ-I constant current potentiometer clockwise to set output current according to require LED working current. 7.Connect LED and test. Note: Please press the button ’ – ’ repeatedly if there is no output voltage. It is a DC power module so it cannot connect to an AC power source! Please don’t short the output. 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 a anti-backflow diode at input positive terminal. ’IN-’ and ‘OUT-’ cannot be connect together, otherwise module cannot support constant current output. Please make sure input power is more than load power. Please step down output power if module is too hot. The module’s output voltage and current accuracy are 0.1V and 0.05A. Please read user manual and all of the description before use.
