Motorola TPS 262 power supply

Motorola TPS 262 is a dual‑rail, rack‑mount industrial power supply used to deliver regulated ±12 V and +48 V outputs to control panels or servo drives. Common failure modes include over‑current protection trips from shorted load lines, capacitor electrolyte leakage in the high‑voltage input stage, and fan motor burnout leading to overheating of the internal regulator. First‑check diagnostics: verify input voltage and polarity with a multimeter; inspect for bulging or leaking electrolytic capacitors on both rails; confirm that the built‑in thermal shutdown is not repeatedly tripping by monitoring output temperatures during a brief load test.[oss-gpt-20b] Post Comment
