Professional diagnostic and board-level repair service for this Fg Elektronik SNT5-20 V PSU5/4 Power Supply.

FG Elektronik SNT5‑20 V PSU5/4 is a 230 VAC/50 Hz industrial power‑supply card that converts mains to regulated DC rails for a controller or servo‑drive board. Common failure modes on this model include electrolytic capacitor degradation, transformer winding insulation breakdown, and regulator IC overheating; visual inspection often reveals bulging capacitors or scorch marks on the PCB. First‑check diagnostics: verify input voltage with a multimeter, measure output rail voltages against spec, inspect for loose or damaged solder joints and test the main switching transistor or MOSFET for continuity and proper gate drive.
