There is a small smd resistor that sets the output range. I don’t know the values for each but I have changed the amps output on some charger boards. On those less resistance made the amps go up. Can you see if there is one resistor on each driver that is a different value?
Look for 0402 resistor below uC chip; 75kOhm is 12Amp, 100kOhm 9Amp, 150kOhm 6Amp (or 3 Amp in case large shunt resistor is marked with "002" which is 2mOhm).
@ led4power,
is there an estimate date for shipping of the products bought in December?
I didn’t receive any e-mail with the shipping info, hence my question.
Thanks in advance
Hello L4P, I’m waiting for a delivery from post office, I’ve ordered some leds from you in December,now they seems stuck somewhere in my country,I will try to contact the post office,anything you can do for It? Will let you know how It ends up after some call
I think I have a never used 17mm version in the 3 amp type that I don’t need. But I have not unpacked a bunch of workshop offs ‘n’ ends yet so can’t even verify for a bit. It might even be a 6 amp; my memory fails me.
