The output DC voltage variation is step less by means of ON LOAD motorised regulator. We use vertical ROLLING CONTACT TYPE voltage regulator, wound with heavy section of copper strip, suitable for 100% continuous duty cycle. The life of these regulators is more than 25 years and have 4 - 5 % better efficiency in comparison to conventional dimmerstat type regulators. - Please note that Rectifiers manufactured by us, we are using plus/minus type (+ 254 Volts OR + 440 Volts) Voltage regulator in "Q" connection - which means that the capacity of voltage regulator required in our Rectifier winding design is 50% in Star connected (+ 254 Volts) model and 30% in Delta connected (+440 Volts) than straight type (0-440 Volts) voltage regulator used by conventional design rectifier winding. - With Plus/Minus type voltage regulator used in our rectifier design, the capacity of Voltage Regulator used remains the same, but the brush current of the Regulator reduces and the reliability of regulator increases. This results in considerable saving in overall power losses of our Rectifier equipment.
