Let me give it a try as I modded today for someone else a MF02S
I am bad at making videos but I post it anyways
actually the PSU voltage meter uses calvin clamps so its reding on contact points on driver to compensate losses on the wires, even if they are 2.5mm²
Measurements
Turbo (measure 3 times and used average later as in video the clamp meter was not prcise)
Input: 15,15V 5.4-5,44A
Output: 13,44-13,51V 5,70-5,74A
Efficiency: 94,4%
I also changed the calibration resistor to get to 6.09A later and did again 2 measurements
15,11V 5,8A
13,6V 6,09A
94,5%
fully charged VTC6 should give this voltage
16,17 5,37A
13,55V 6,04A
94,25%
I would like to mod my L6 with a new type Osram KW CSLNM1.TG LED.
In this LED the thermal pad is electrically neutral, this means there is no need for LED PCB/driver GND isolation.
Max suggested current is 5.75A (Vf~3,40V)
It was within Germany and he sent me the whole light
The driver was fine, just the new thermal enhance design does not allow a bad soldering job on the LED+ terminal
here clearly can be seen that the wire solder blob also touches the ground viases that are about 0.75-1mm next to the pad, the buck chip detects short and stops output
best is to solder the wire straight up or 180° rotated pointing to the capacitor so the ground plane is clearly visible and no short risk
I know that coil characteristics degrades while heat increase so there must have some addition over threshold, but how about Coilcraft XAL7030 series? Are those still to weak?
