We provide an array of battery charger which is one of the most reliable load balancing electrical DC power units. When induced with AC voltage the power gets loaded along with battery in it, till voltage reaches 11.2 volts the battery is cut off from the load to prevent the over discharge.
It has 3 modes of operation:

  • Constant Voltage Mode (Float Mode). In the float mode the battery voltage is kept at 13.2 volts (can be set by preset). In this mode the battery draws only trickle charging current required to make up for its internal losses
  • Constant current Mode (Boost Mode):- In the boost mode the charger output voltage is gradually increased to 14.4 volts (settable by preset) keeping always the battery charging current constant (5 Amps constant current charging). When the battery voltage reaches the 14.4 volts level, the charging mode is changed automatically to float mode
  • Taper Mode for deep discharge The float or boost mode is selected automatically depending upon the status of battery


Advantage of switch mode FCBC with conventional FCBC:

  • High Efficiency Batteries
  • Small size and less weight: The voltage control in conventional FCBC is done by means of a Triac or SCR pre regulator which provides coarse control and fine control is achieved by means of a voltage dropping device which is a series pass resistor. This results in high power dissipation and low efficiency. Also since the step down function is done by a line operated 50Hz transformer, the equipment tends to be bulky. In contrast in switch mode FCBC the regulation is achieved by means of PULSE WIDTH MODULATION of the switching device. Thereby the efficiency achieved is very high (80%). Also the voltage step down function is done by using high frequency (30 KHz in the present case) ferrite cores which results in small size and less weight
  • Single PCB construction resulting in less wiring and less workmanship flaws
  • Better Transient response to both load and line changes
  • Wide Operating Range
