Important Notes

• This is a power supply module, so the output voltage must be higher than the input voltage. Otherwise, it will not work normally.
• The USB output is not fixed at 5V, it is 1V~24V. Therefore, please be careful when using USB.
• If there is no output voltage, turn the CV potentiometer counterclockwise more than 20 turns.
• This is a DC power module, so it cannot be connected to AC power.
• 'IN-' and 'OUT-' cannot be connected together, otherwise the module cannot support constant current output.
• Please ensure that the input power is greater than the load power.
• If the module is hot, please reduce the output power.
