CEPL's thyristor controlled rectifiers use advanced digital control technology with user- friendly operation, flexible interfaces with state of art control features, options of touch screen and text display, 6/12 pulse thyristor bridge, a mains isolation transformer, standard alarms and meters etc. As they have an advance DC regulator for all the rating, there is no dropping diode for online charge boosting. They operate either as a stand alone system or in a parallel manner with the load shared between battery chargers.
