Efficiency measure on my 12V MF02S driver
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 reading on contact points on driver to compensate losses on the wires, even if they are 2.5mm²
Turbo (measure 3 times and used average later on video the clamp meter offset were off 70mA)
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%
2A
Input: 15,73V 1,766A
Output: 12,06V 2,12A
Efficiency: 95,5%
500mA switching frequency is over 1 MHz as output voltage low and input high
Input: 15,94V 415mA
Output: 11,2V 502mA
Efficiency: 85%

Niwalker Connections are special for the Aux buttons
The left row is for the aux buttons
V is 5V for Turbo and 10X for the switch
10X increases current by 10 max. is Turbo
T turbo even when electronic lock out or light off
M reduced the current by factor of 10
needs to be connected to (G) ground pad on 2. wire
right
G common Ground
L Switch LED MCU controlled
S Switch for UI ramping settings
