Function description:3.1. The module has input/output, ON/OFF two buttons: IN/OUT button to switch the input voltage and output voltage indicator, long press to switch the output current display; ON/OFF controlled by the buttons output on or off, long press Set power ON the default output state is on or off ączony.3.2.CC is a current setting potentiometer, rotation right, can increase the set current, when the load current reaches the set current, enter the constant current state, the CC constant current indicator (red) lights up; The right CV is the voltage setting potentiometer, turn right, can increase the output voltage. The ON indicator is an indicator of the output status when the output voltage is on, otherwise off.4. How to use:4.1. Used as a regular boost module with overcurrent protection(1), adjust the constant CV voltage so that the output voltage reaches the desired voltage. (2) directly connect the output end with a short line (can shorten the output end directly!). Adjust the DC potentiometer CC so that the output current reaches the specified value of overcurrent protection. (For example, the current value displayed by the module is 2A, so the maximum current can only reach 2A when using the module, I red constant voltage and the current indicator is on when the current reaches 2A, otherwise the indicator is off)Note: when using in this condition, there will be a voltage drop of 0 - 0.2V due to the current output sampling resistor. At the same time, the input and output wires will have a certain linear voltage drop, this is a normal phenomenon!4.2. Used as a chargerWithout the constant current function, the module can not be used to charge the battery, due to the power of the battery and the pressure drop of the charger is large, which causes the charging current It is too large, causing damage to the battery, so at the beginning of the battery to charge constant flow, when the charging to a certain extent automatically switches back to constant voltageCharging. (1) determine the float voltage and charging current for which you need the battery (if the lithium battery parameter is 3.7V/2200mAh, the float voltage is 4.2V, and the maximum charging current is 1C, which is 2200mA)(2) under no-load conditions, the multimeter measures the output voltage and adjusts the potentiometer constant voltage so that the output voltage reaches the float voltage. (If the 3.7V lithium battery is charged, adjust the output voltage to 4.2V)(3) measure the output short-circuit current with a 10A current meter (directly connect the two test leads to the output terminal), and adjust the DC potentiometer so that the output current reaches a certain value of charging current; (4) Connect the battery, charging. (Steps 1, 2 and 3 are as follows: input termination power supply, the output is not connected to the battery load)4.3. Used as LED
