Note:
After the product triggers protection mechanism, output will automatically turn off, and LCD screen will display protection code. Press any button to exit the protection interface.
To ensure the accuracy of calibration, only when the voltage is over 12V can voltage be calibrated. And only when the current is over 1A can current be calibrated.
The input terminal IN negative of the module must not be short-circuited with the output terminal OUT negative, otherwise the constant current function will fail.
Please ensure that the power of your power supply is greater than the power required by the output load.
When users need the module to output at full load, input voltage needs to be larger than 8V. When input voltage is 5V, output power is about 15W. The maximum current of module is 4A, which is limited by the maximum output power. For example, if the output is 17V, current should not be greater than 2A.
When this module is used over 3A, 35W, please strengthen heat dissipation devices.
The module has input under-voltage protection function. The default value is about 4.8V (can be set). If it is lower than this value, output will be automatically disconnected (Attention: The voltage at the port of module is lower than the under-voltage protection threshold. When input current is relatively large, please not ignore the divided voltage on input wire).
