Battery Charger
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
High Power Rectifiers
We manufacture a gamut of high power rectifiers that can be divided into different forms. Our range of high power rectifiers and SCR / IGBT based rectifier posses robust analog and digital control designs and is available in 6, 12, 18 and 24 pulse systems which improve regulation, reduce supply side harmonic content and reduces output ripple. These high power rectifiers are also used in hazardous areas and have facility for interfacing with client SCADA systems.

Our high power rectifiers are available in following modes:

  • Power Supply for Cathodic Protection of buried pipeline and structures.
  • Industrial Processes such as Electro- Winning, Electro-Rectifying and Electro Plating.
  • Hydrogenation and Chlorination.
  • Rectifiers for Electro Static Precipitators.
  • EMU / DMU Rectifiers.
  • Battery Chargers

Our Cathodic Protection rectifier is used in remote monitoring operation and to control data which is transmitted over GSM and dedicated fiber optic links. The division of rectifiers gives full systems with auxiliary equipment's such as switchgear, power factor correction and harmonictiter.


    • Variac Controlled (Steppies): With the help of stepless variac the output is controlled from zero to the rated value and it also controls the operation of rectifiers
    • Static Variac Controlled: By controlling the firing angle of thyristor, the operation and output of rectifiers can be controlled
    • Thyristor Controlled: Thyristor rectifier is available in 6, 12 or 24 pulse configuration. The thyristor which is considered secondary of the transformer is mainly used to control rectifier output

      Type of Cooling:

      • In high atmospheric temperature and high corrosive conditions, our range of rectifiers ensures optimum performance and high reliability.
      • For effective cooling, the transformer choke diodes are immersed in oil tanks.
      • For high rating "forced Air cooling", we use “natural air cooled scheme in a proper ventilated room.
      • The internal components are cooled with the help of blower fan. 

      The transformer is available in two different forms such as oil cooled as well as air cooled / forced cooled. Our rugged and sturdy transformer is widely used to step up or step down the input supply effectively. The hexa phase rectifier unit is to connect two star points of inter phase transformer.

      Protection: For protection of our rectifiers, we undertake various protection schemes that re enlisted below:

      • MCB / MCCB at Input or Output
      • Snubber circuits for devices
      • Temperature control for devices and transformer
