I am trying to fix and decrease our charger failures.
This charger has an input fuse (AC Mains 3 Phase 50hz) and during charging battery if this fuse is closed manually
would it harm to electronics of chargers, it has input filter caps a pfc circuit and after a smps with constant current.
I am working on a circuit which will detect ac input cut event and immediately it will send stop charge command to charger,
What do you kindly think? is it necessary ? or it can save some failures?
Thank you very much
