Why the regulator control is superior to thyristorised control in Rectifiers?

• The regulators in plating application are of better quality, as they are manufactured adopting the German and European technology due to as explained in the advantage.
• Other manufacturers of rectifiers have shifted to thyristors controlled rectifiers, as they do not have the technology of rolling carbon roller regulators.
• Other manufacturers of rectifiers claim that thyristor controlled rectifier cause less losses in comparison to regulator. They compare thyristor regulator with sliding carbon type regulator. But, in our case their claim does not prove true. We use vertical coil type rolling carbon regulator. The copper section is three times so the losses are almost 1/6 or 20%.
• In our regulator, the roller moves on both sides of the coil to give ± 440 V or ± 254 V output. We design the rectifier in 'Q' connection in which the regulator current is half the line current so losses are less and life is much more.

Starting Circuitry
We design premium quality silicon rectifiers, which are capable of supplying 3 phase 50 Hz. Ac input. They can be used for the operations at any voltage between 380 and 440 volts in India. We specialize in manufacturing these rectifiers for 60 Hz AC and any other voltage.

It is highly recommended that, during the course of maintenance or in case a fault occurs, the input should be connected to the power rectifier through a proper protective device for providing both personal and system positive protection.

DC Output Control
Variable output controls are designed for the purpose of controlling the voltage or current or its operating range by varying input voltage to the main transformer primary. The DC output voltage variation can be obtained steplessly 0-100% by using POWER make on load roller type voltage regulator.
