Saft Nife SMR 48/25M Power Supply

Saft Nife SMR 48/25M is a 48‑VDC, 25‑A switched‑mode power supply used primarily as a battery charger or rectifier in industrial energy‑storage systems. Common failure points for this class include degraded MOSFETs or IGBTs in the output stage, blown electrolytic capacitors on the input and output rails, and overheating of the internal heat sink due to inadequate airflow or fan failure. First‑check diagnostics: verify 48 V input voltage and continuity to the output rail; inspect for visual signs of capacitor bulging, burn marks, or loose solder joints; and confirm that the cooling fan is operating and the heatsink is free of dust buildup.[oss-gpt-20b]
