ProtekG has a 28 years of experience in designing and manufacturing various types of Industrial Float & Float cum Boost charger chargers. BPS Industrial Float Chargers FCBC, FCBC Battery Charger, and Float Charging are designed to supply a constant DC source for continuous load and intermittent DC loads and simultaneously keep the connected batteries in fully charged condition. These are Constant Current – Constant Voltage chargers. Chargers are Transformers based, have a full bridge rectifier consisting of SCR / Diode or SCR-SCR modules with a phase angle control loop to automatically control the charging rate for a wide range of batteries. BPS chargers are suitable for Float Charging all kinds of batteries like VRLA, Ni-Cad, Tubular, Plante, etc. Float Charging


The primary functions of a Battery Charger are:

a) To Boost charge the discharged battery,

b) To float charge the battery to maintain its self-discharge losses.

c) To supply DC load with Mains ON condition.

While selecting the right type of chargers for specific applications, the following points may be considered:

a) Application critically, For critical application, the charger selected must have very high redundancy.

b) Location of installation, For installation at remote locations, high redundancy is required.

c) Type of battery and

d) Cost factor
