Etasis EFRP 465 Power Supply

Etasis EFRP‑465 is a 460 W, 100‑240 V AC, 1U rack‑mount redundant power supply designed for server and industrial control chassis. Common failure modes include degraded electrolytic capacitors on the DC output rail, failed fan or thermal protection circuitry, and overcurrent/overvoltage trip of the internal MOSFETs due to PCB contamination or solder joint fatigue. Begin troubleshooting by verifying input voltage with a multimeter, checking the 12 V/5 V/3.3 V rails for correct output levels, inspecting the fan operation and thermal pads, and reviewing any diagnostic LEDs or status codes that indicate protection trips.[oss-gpt-20b] Post Comment
