The Etasis IFRP‑462 is a 460 W N+1 mini‑redundant power supply designed for industrial control and data‑acquisition systems, accepting 100–240 VAC at 47–63 Hz with dual 8 A inputs and providing 25–30 A output. Common failure points in this class include capacitor degradation on the secondary side, overheating of the MOSFETs or IGBT switching devices, and failure of the internal fan or heat‑sink mounting. First‑check diagnostics: verify input voltage and current with a multimeter; inspect for visible signs of thermal damage or blown fuses on both primary and secondary rails; confirm that the redundant pair shares load by measuring output currents when one unit is isolated.[oss-gpt-20b]
