Variable Auto Transformer with Silver Plated Commutator is designed with low flux density, low current density and high insulation capacity. The Variable Auto Transformer provides an output voltage waveform which is distortion less replica of the input voltage wave form. The Variable Auto Transformer is facilitated with silver plated commutator which enables the unit to withstand high overloads and maintain constant contact drop. Variable Auto Transformer with Silver Plated Commutator is designed with unity power factor of 0.8.
