Setting over-current protection

<span style=”font-weight: 400;”>I recently bought a Drok converter.  When I received it I tested it – I set the output to 5V and the over-current protection to 500mA.  This worked great, it was easy to set up and repeated when I tested it.</span>

<span style=”font-weight: 400;”>Now I need to change the output.  I want 12V coming out with a 300mA over-current protection.</span>

<span style=”font-weight: 400;”>I turn both the CC and CV potentiometers counterclockwise. Then, with nothing attached, and the CC light off and the output light on, I set the voltage to 12V.  </span>

<span style=”font-weight: 400;”>Next, I hook up the multimeter to short out the circuit.  As I turn the CC clockwise the voltage drops to zero – so I try to increase the voltage a little, but before I get too far the wire attached to OUT+ starts to smoke.  The wire is a dupont type jumper wire that goes to my multimeter.</span>

<span style=”font-weight: 400;”>Any thoughts on what I am doing wrong?</span>

Hello Mark,

According to your description, we are sorry it should be  burned.

Once you short output ports, voltage regulation can’t be operated in that case.

Best regards,
