Etasis EPR-305 power supply

The Etasis EPR‑305 is a 300 W N+1 redundant power supply designed for server or industrial control chassis, providing dual input paths and automatic failover. Common failure modes on this model include fan motor burnout, capacitor electrolyte leakage, and failure of the main MOSFET array due to overcurrent or thermal overload; these often manifest as no output voltage or intermittent shutdowns. First‑check diagnostics: verify 115/230 VAC input levels and continuity on both redundant rails, measure output voltages (12 V, 5 V, etc.) with a multimeter, inspect the PCB for bulging capacitors or burn marks, and check the status LEDs or diagnostic port for error codes.[oss-gpt-20b] Post Comment
