PowCon BD 103025 circuit board

PowCon BD 103025 is a high‑power industrial drive control board used in welders and heavy‑equipment motor drives. Common failures on this model include burnt or tripped MOSFETs/IGBTs, damaged gate driver ICs, and degraded capacitors that cause over‑current protection trips or erratic output voltage regulation. Initial diagnostics should verify the main power supply rails (48 VDC input, 400 VDC output) for correct voltage and ripple, inspect for visible arcing or component discoloration, and check all I/O connectors and signal traces for continuity and proper logic levels before proceeding to detailed fault isolation.[oss-gpt-20b]
