We present high-precision Variable Auto Transformer that is simple and provide a variable voltage output from the fixed input voltage. It is very effective in controlling A.C. Voltage such as A.C. current, D.C. voltage & current intensity of light & heat, and speed of D.C. motors. These transformers confirm to IS 5142-1969 and are suitable for a wide range of current and voltage (240 V & 415 V) and 3 phase supply. These single phase auto transformer and three phase auto transformer are suitable for places which require a smooth voltage.
The core of the auto transformer is made of high grade, non aging continuous CRGO strip and carefully annealed that results in low magnetizing current and core losses. The output is linear and this transformer does not produce any distortion in the wave form. It can withstand heavy overloads of short durations such as starting currents of motors. These single phase auto transformer and three phase auto transformer give an uninterrupted service in tropical areas.
