CIAR SpA SU15/M1 (part 2151100690) is a dedicated 230 V industrial power supply module used in lift‑chair and recliner actuator control units. Common failure modes for this class include transformer winding degradation, electrolytic capacitor electrolyte leakage or bulging, fuse tripping, and output voltage sag due to overheating or PCB trace damage. First‑check diagnostics: verify input mains voltage and polarity, inspect the unit for visual signs of burn marks or swollen capacitors, test the output rails with a multimeter while the load is disconnected, and review any error codes displayed on the host controller for indications of power supply faults.[oss-gpt-20b] Post Comment
