Core Function: This dual-function integrated PCB serves two critical roles inside ABB medium voltage converter racks. First, it acts as a precision high voltage divider to step down raw MV DC bus voltage into low-voltage measurable signals safe for control circuits. Second, it provides galvanically isolated signal conditioning for analog feedback: motor current, DC bus voltage, heat sink temperature, and gate unit status signals from power stacks. It filters noise, amplifies weak transducer signals, and transmits calibrated analog data to the main drive CPU board. Built-in hardware protection locks out signal output during overvoltage, overtemperature, and short-circuit events to prevent control board damage, supporting fault diagnostics and predictive maintenance for heavy-duty MV motor d
