Rectifiers & Electronics supplies DC High Current Variable Auto Transformers. Rectifiers & Electronics is an ISO 9001:2000 certified company. The DC High Current Variable Auto Transformers is used where voltage control is needed. It is made from 2 A to 2000 A for Single and Three Phase. This compact easy to operate auto transformer has special insulating paper for transformer winding. It is also provided with a motor drive.
RE` Variac Continuously Variable Auto Transformers usually form part of system in which other components such as transformers, diode etc are used as power components. The proportion between iron section and copper turns is such that at the maximum AC applied voltage maximum no load current is within 5%. The insulation of the wire over one face is removed the output is taken between one end and the brush arm. The moving brush contacts the next turn before it breaks away from the previous turn, thus, there is no interruption in output voltage.
The DC High Current Variable Auto Transformer is designed to boost the Output, Voltage by 12% than the input voltage. Three Single phase units are connected in star for 3 phase four wire system. The brush arms are moved by a common shaft and the star point is connected to the neutral of the system. Custom made capacities can be manufactured and the manufacturing range covers up to 2000 Amperes in three phase.
