DC Rectifier Transformers

Highly efficient DC Rectifier Transformers are acknowledged for their low emission rate, less power loss rate, reliable operation and low noise generation level. Short circuit protection mechanism and long working life are their key attributes. Featured with <5% ripple content and <35 degree temperature rising level, these transformers have A class insulation standard. Easy to maintain, these DC transformers utilize silicon diodes, carbon rollers, constant voltage controller and cold rolled grain oriented lamination core and electrolytic type copper strip to optimize their performance level. Three phase motor capacity, application of toroidal type coil, low servicing charge, ease of installation and low operation cost are the main factors behind their huge demand in the market. We are a prestigious supplier and manufacturer of DC Rectifier Transformers.

Advantage of Roller Type Regulator as Compared to Thyristor Control:

Roller Type Regulator

Thyristor Control

No wave form distortion at any load.

Wave form distortion.

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.

It is like cutting the wheel by 50% and then moving the wheel i.e. wave form is cut as shown at full magnitude.

Higher power factor of more than 0.95 is achieved.

The power factor is lower between 0.5 to 0.9

The system is simple and can be repaired and maintained even by simple mechanic.

The system is specialized and needs specially trained Electronic Engineer to repair and maintain.

Over all losses are less.

The cost of replacement is very high.
