MP1584EN DC to DC buck converter adjustable power supply module 24V to 12V 9V 5V 3V

NOTE:
Pay attention to the positive and negative poles;
If used at large current for a long time,heat dissipation is recommended;
Do not use light load(less than 10% of the output power) or no-load;
If the output voltage is always equal to the input voltage,turn the potentiometer clockwise for more than 10 turns.

You can adjust the voltage by placing a multimeter synchronously at the output, and adjust the potentiometer with a screwdriver. It can achieve precise voltages with tiny adjustments.
Do not short-circuit the output.
When setting parameters, ensure that the output voltage is stable before using the module.
