Float-cum-boost chargers (FCBC)
5 A – 200 A
Thyristor-controlled, transformer-isolated, built for substation duty. Heavier and less efficient than SMPS, and far more tolerant of dust, heat and a rough supply. Specified where the charger has to keep working for twenty years with basic maintenance.

Float Cum Boost Charger — questions
Anything not covered here, call us — most of it is faster to answer on the phone.
Can an FCBC run without a battery connected?
Yes, in float mode it will regulate on its own, but ripple rises noticeably because the battery is no longer acting as a filter. If the charger is intended to run battery-less for extended periods, tell us at the quotation stage so we can specify the output filter for it.

Where we supply and attend
Float Cum Boost Charger units are built at our Pune works and delivered, installed and commissioned across the city and the industrial belt around it.
Outside these areas we contract individually against distance, and we will tell you honestly if the response time you need is not one we can hold to. All areas served
Not sure this is the right size?
Send the load list. Sizing against inrush rather than running load is where most undersized installations go wrong, and it costs nothing to check.
