Driving LED simple adjustment of voltage and current methods (such as 10 series LED current 1. 7A 50W)
Module input power output is not connected LED, adjust the CV output voltage to approximately 34V;
CC multi-turn adjustment counterclockwise until you hear potentiometer which sent da da sound (potentiometer has been adjusted to the end);
Connecting LED, and the LED anode and cathode in series between the module outputs a current meter (ammeter internal resistance as small as possible, ammeter connecting wire as thick, short, so as not to affect the debugging results);
Power, this time should not be light or micro-LED light, observe the ammeter shows the current, slowly clockwise until the ammeter shows about regulating CC 1. 7A.
Remove the meter, direct electrical test machine.
