Salient Features
MUSKAAN’S rectifier equipments are wound with electrolytic Prime grade copper strip to minimize power losses, in comparison to Aluminum conductor used by many other manufacturers. Our equipments are designed liberally as per capacity and are Ideally suitable for marginal over loading conditions.

We use vertical rolling contact type voltage regulator wound with heavy section of copper strips suitable for 100% continuous duty cycle or industrial applications, in comparison to conventional wire wound regulators used by other manufacturers. The carbon rollers move on both sides of the winding.

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.

LAMINATION CORE: We use imported CRGO lamination core which have minimum power losses and results in better efficiency of equipment and saving in energy bill.

PAINTS: We are painting the equipment with Epoxy paint which is resistant to acidic environment of plating process and enhance the life of the equipment by preventing it from corrosion.

METER: We use reputed make AE/RISHAB make DC meters only which are very accurate and durable.

CONSTANT VOLTAGE CONTROLLER (CVC) (OPTIONAL): We offer CVC Electronic attach-ment with rectifier equipments, which will maintain constant Output Voltage or current as per setting automatically irrespective of input voltage variation.

SERVICING: MUSKAAN’S have maintained enviable reputation in market in after sales service. This fact can be verified from any of our customers.

Advantage of Roller Type Regulator as Compared to Thyristorised Control

Roller Type Regulator Thyristorised Control

  • No wave form distortion at any load.
  • Electrical wave form is like a moving wheel. For 50% Rated Voltage the Dia of wheel is reduced accordingly i.e. magnitude for a wave is decreased.
  • Higher power factor of more than 0.95 is achieved.
  • The system is simple and can be repaired and maintained even by simple mechanic.
  • Over all losses are less.
  • Wave form distortion.
  • It is like cutting the wheel by 50% and then moving the wheel i.e. wave form is cut as shown at full
  • magnitude.
  • The power factor is lower between 0.5 to 0.9
  • The system is specialized and needs specially trained Electronic Engineer to repair and maintain.
  • The cost of replacement is very high.
  • Over all losses are more.
