    PCB Re-Design 6 days left
    VERIFIED

    I have a tested PCB design, I simply need the design to be more space efficient. It drops the DC voltage from a battery network down to a lower voltage and uses an external 12VDC signal to trigger a relay to fire the shunt coil on an MCCB using the battery voltage as it's supply. The OHM and wattage of the resistors mounted externally can be selected to allow the PCB to work with different ...

    Adapt PCB from Eagle to KiCAD and increase performance from current 80A to 200A with peaks of 400A (specify heatsink for the design). Theoretically, used MOSFETs (FDMT80080DC, two in parallel) should be capable to handle 200A requested currents if they are cooled properly, but heatsink must be calculated. Also the Würth press-fit elements are already capable to handle 200A in theory. Probabl...
