    Current Limiter design for HP server PS - DPS-600PB

    Good Morning. I am on a build of this great mod here. The over voltage protection is adapted already and I can go from 10 to 14,4 Volts under full load. Now I'm working on the current limiter. Because of the low Quality of the "shunt_connections.jpg" photo, I don't know where exactly to...
