Saft Nife SMPS 48V Battery Charger

The Saft Nife SMPS 48V/15A Battery Charger is a switch‑mode DC power supply used to charge industrial battery banks from mains input. Common failures on this model include tripped or failed output fuses, degraded rectifier diodes (especially the 48 V/30 A SMR variants), and overheating of the internal switching MOSFETs due to poor heat sinking. For similar industrial chargers, inspect the power‑in connector for loose pins, verify the input voltage and current rating, then check the output voltage with a multimeter while the unit is powered on; look for any obvious signs of component burn or corrosion on the PCB. Finally, review any diagnostic LEDs or error codes that may be displayed on the front panel.[oss-gpt-20b]
