Hello Diego Monzon,

Thanks for writing in.

Could you please tell us more details about your operation? Before connecting your device,  did you short the output terminals and then turning  current potentiometer?

In addition, please kindly notice the current adjustment here is for limited the max output current. It doesn’t mean actual output current is as the same as preset value.

For example, if you set 1A , but your device only need 0.75A, actual output should be 0.75A.
If device want to draw 2A , in that case, output will be limited to 1A.

Best regards.
