Introduction to Functions: 1. The module has two buttons IN/OUTQN/OFF: IN/OUT button switches the display of input voltage and output voltage, long press can switch output current and output power display; ON/OFF button controls output ON or OFF, long press can set The default output state is ON or OFF at the second power-on. 2. CC is the current setting potentiometer. Turn clockwise to increase the set current. When the load current reaches the set current, it enters the constant current state, and the CC constant current indicator (red) lights up; the CV on the right is the voltage setting The potentiometer, rotating clockwise, can increase the output voltage. The ON indicator light is an output status indicator light, which lights up when there is voltage at the output terminal, otherwise it goes off.
NOTE: 1. Module input IN- must not be short-circuited with output OUT-, otherwise the constant current function will fail. 2. Please make sure that the power of the power supply is always greater than the power required by the output load! 3. If the module wants to output at full load, the input voltage must be above 8V. When the input voltage is 5V, the output power will be about 15W, and the voltage and current meter will fail. The current value of the module is 4A, provided that it is limited by the rated output power, for example, when the output is 17V, the current should not be greater than 2A. 4. The module is equipped with output short-circuit protection. After the short-circuit protection, the module will automatically turn off the output and re-power on the module to restore it. If your power supply does not have output current limiting protection, it is recommended to connect a fuse in series in front of the module input. 5. The module has an input under-voltage protection function. The default is about 4.7V. When the value is lower than this value, the output will be automatically disconnected, and the module will be re-powered to recover (note the voltage at the module port, when the input current is relatively large Donat ignore the voltage divider on the input wire).
