Sortex A04-3357 Circuit Board

The Sortex A04‑3357 is a high‑current industrial power supply control board typically used in sorting or conveyor systems. Common failure points on this class of boards include burnt MOSFETs, damaged gate drivers, and degraded capacitors that can cause over‑voltage spikes or loss of regulation. Begin by verifying the input voltage and checking for any visible component damage; then test the output current capability and inspect the power‑stage transistors for overheating or leakage. Finally, review any diagnostic codes from the attached controller and confirm that all I/O signals are within spec before proceeding with deeper diagnostics.[oss-gpt-20b]
