Starting Circuitry :
Jindal's Rectifiers are designed for 3 phase, 50 Hz, AC input supply and are available for operations at any voltage between 380 and 440 volts, covering a wide range of voltage fluctuations. It is recommended that the input of the rectifier should be connected through a proper protective device, to provide positive protection to personnel and the system, in the event of maintenance or in case a fault occurs.
DC Output Control :
The function of the variable output controls is to control the voltage or current or its operating range by varying input voltage to the main transformer primary. The DC output voltage variable is achieved steplessly 0-100% by means of an ON LOAD roller type Jindal's make voltage regulator.
