Adjustable buck regulator module constant voltage constant current LCD digital display voltage current power crystal case high power

Function Description:
-There are two ons on the left side of the module:IN/OUT,ON/OFF:IN/OUT on to switch the input voltage and output voltage display,long press to switch the output current and output power display;ON/OFF on control output ON or OFF,Long press to set the next time the default output state is ON or OFF.
-The right side of the module has two ons:’ ‘ and ‘-‘. Press the ‘ ‘ on to increase the output voltage by 0.05V.Press and hold it to increase it continuously. Press and hold it again for a continuous slow step increase of 0.1V and 1V. ‘-‘ on, the output voltage is reduced by 0.05V,long press can continue to reduce,and then long press to reduce the step by 0.1V and 1V.
-ADJ-I is a current setting potentiometer, clockwise rotation,can increase the set current,when the load current reaches the set current, enter the constant current state, CC constant current indicator (red) lights up.The ON indicator is the output status indicator.It is on when the output has a voltage,otherwise it is off. The CHAR indicator is the charging indicator. When charging,it is on.The FULL indicator is full.If the set constant current value is 2A,the charging When the current reaches 0.2A or less,turn on the lamp, the FULL lamp is on,and the CHAR lamp is off.
