• Our Rectifier equipments are wound with electrolytic prime grade copper strip to minimize power losses. In comparison to Aluminium conductor used by many other manufacturers. Our equipments are designed liberally as per capacity and are ideally suitable for marginal over loading conditions.
• Annealed Copper bus bars/ Aluminium Bus Bars of electrolytic grade with conductivity greater than 99.99% as per IS : 613-1984 are used.
• DIODES : Silicon Diodes are tested in house. Similar PIV batch and same forward drop diodes are used in the equipment for equal load sharing and reducing the power losses of diodes. The diodes in the rectifiers are fitted with suitable heat sink and hole storage resistors and capacitors.
• IPT : Inter Phase Transformer-IPT is connected between two star points of the secondary of the main transformer. The IPT improves the commutation, there by increasing the rating of the Rectifier.
• Lamination Core : we use imported CRGO lamination core which has minimum power losses and results in better efficiency of equipment and savings in energy bill.
• Meter : we use reputed make – AE/RISHABH or as per customers requirement.

• Constant Voltage Controller (CVC)
  • Application : The CVC will automatically maintain a constant output voltage as per setting, irrespective of input voltage variation
  • Advantage : By using CVC, uniform quality of plating can be maintained, thereby controlling excessive consumption of plating raw material at high voltage.
• Constant Current Controller (CCC)
  • Application : The CCC will automatically maintain a constant output current as per setting, irrespective of inpt voltage variation.
  • Advantage : By using CCC uniform quality of plating can be maintained, thereby controlling excessive consumption of plating raw material at high voltage.
• D.C. Overload Trip System
  • Application : The DC Overload Trip system will sense the signal from the output of the Rectifier and trip the main contactor in case of overshooting the set range.
  • Advantage : By using the DC Overload Trip System, the diodes will be saved during any accidental short circuit in the bus bars or in the tank.
• Zero Run Down System
  • Application : with the help of Zero Run Down System, once the Rectifier trips or is switched off while working, it will automatically start from 0 volts when restarted.
  • Advantage : This saves the diodes from sudden load current, thus increases the life of the equipment.
• Signal Isolators to enable automation / PLC compatibility
  • Application : The signal Isolators can be used to avoid the milli-volt drop of the Ammeter / Voltmeter signals. The Isolators can give output in milli-Volts / milli-Amps.
  • Advantage : Ideal for use when the Voltmeter/Ammeter panel is kept too far from the Rectifier. These signal Isolators are also necessary for the input signals to the PLC panel, i.e. to make the Rectifiers PLC-compatible.
