Float Cum Boost Charger (FCBC) as the name
indicates, is a two-in-one functional combination
of a float charger and a Boost charger. Under
normal condition FCBC works as a float Charger.
When the mains fail, battery takes over supply to
the load. On resumption of power, FCBC switches
to the “Boost Mode,” Boost charges the
discharged battery and returns to the “Float
Mode”, after the battery is restored to full charge.
All along, it supplies uninterrupted DC power to
the load.
