    I have just purchased a

    https://www.amazon.co.uk/gp/product/B00T2L76FA/ref=as_li_tl?tag=proeng01-21&keywords=buck+converter

    I want to use it to drive between 1 and 4 less at a constant current of 700ma, i cannot work out how to get it to use constant current mode?

    Regards

    Wayne

    Hello Wayne Richards,
    Here is a method:
    1. Adjust constant-voltage potentiometer to make output voltage reach the voltage value which you want.
    2. Use 10A multimeter to measure short-circuit output current (directly connect two meters to output interface), at the same time, adjust constant-current potentiometer to make output current reach preset value.
    Best regards.
