The Vero VP80‑2B is an 80 W switched‑mode AC/DC power supply with two regulated outputs, designed for rack‑mount industrial applications such as control panels and servo drive backplanes. Common failure modes in this series include output voltage sag due to failed output capacitors or MOSFETs, overheating from inadequate ventilation or overloading, and protection trip faults caused by shorted secondary windings or damaged input filtering components. First‑check diagnostics: verify the input AC voltage and polarity, measure each output under no load for correct voltage levels, inspect the PCB for bulging electrolytics or burn marks, and review any fault codes or LED status indicators on the unit’s front panel.[oss-gpt-20b]
