Saft Nife SMP/72/10 12/3 Power Supply

Saft Nife SMP 72/10 12/3 is a 120‑V AC to 24‑V DC industrial battery charger rated at 30 A (≈720 W). Common failure modes for this unit include failed bridge rectifier diodes, degraded electrolytic capacitors on the output filter, transformer winding insulation breakdown, and malfunctioning control ICs that can trigger over‑temperature or over‑current protection. First‑check diagnostics: verify input voltage and current at the AC terminals; inspect the output DC rail for correct 24 V under load and check for excessive ripple; visually examine the rectifier bridge and electrolytic capacitors for bulging, leakage, or burn marks; review any fault codes displayed on the unit’s diagnostic LED or panel.[oss-gpt-20b]
