Efratom VME100‑3‑M160 (105450‑001) is a high‑current industrial power supply module used in motor control and automation systems. Common failure points for this class include degraded output regulation due to aging MOSFETs or capacitors, overheating of the internal heat sink, and tripped protection circuits from overload or short‑circuit events. First‑check diagnostics: verify input voltage and polarity with a multimeter; measure output rails and compare to spec; inspect for burn marks, bulging electrolytics, and ensure the cooling fan (if present) is operational. If outputs are out of tolerance, perform a continuity test on the power path and review any error codes from the host controller.[oss-gpt-20b]
