Auto Transformer

Additional Details

We manufacture and supply Auto Transformers that are more efficient compared to the conventional ones. The Auto Transformers we offer regulates the voltage in a better fashion and is cost effective. These Transformers are designed and manufactured using less copper. These Transformers are used both in Synchronous motors and induction motors. Primary and secondary shares same common single winding in this kind of Transformers.

Features:

• RUGGED CONSTRUCTION: Varistat are designed for trouble free operation in industrial use
• It is designed to give maximum life under extreme conditions
• HIGH EFFICIENCY: Varistat designed with low flux density, low current density and high
• Insulation standards. Selection of carbon from the best grade of raw material will keep a high standard of quality of varistat
• Excellent regulation: Varistat have minimum voltage drop in from no load to full load
• Low magnetizing current: Varistat made with high quality grain oriented silicon steel, in adequate quantity so the iron losses are controlled to minimum. the no load current is always less than 3% of the ruled current
• No wave form distortion: Varistat provides an output voltage wave form which is faithful and distortion less replica of the input voltage wave form
• Load capacity: Varistat is designed with unity power factor of 0.8. We can put many over load on it because of its Excellent design sufficient off time is provided to reduce the temperatures build up specially when repeated over loading takes place
• Smooth and linear output: Carbon brush is in constant contact with more than one turn. (Voltage between the turns is very less) Sparking is avoided & output can be set very easily at any point
• Silver plated commutator: A special silver plating technique is used on the commutator enabling Varistat to withstand high overloads and maintain constant contact drop. It also insures smooth operation, long life and resist to corrosion
• Low operating torque: A smooth commutators and perfect assembly of coil & well centered bushes results in very low operating torque which increases life of motor/ varriac
• Carbon depositions: Especially up to 10 amp Varistat are available with square or round carbon, because of round in shape it rotates on commutators, No traction between the carbon and commutator, so carbon deposition is very less when we use the round carbon. No wear and tear in carbon's diameter, as a result carbon replacement is not required for very long time
• Double wound Auto Transformer: Specially designed double wound Autotransformer have been developed for voltage stabilizer application. These Varistat is also available with inbuilt 12v DC motor, which is very cost effective and time saving for servo manufacturer. These varistat will eliminate the need of buck-boost transformer & AC or DC external motor, its gears, its couplings and other mechanical requirements in stabilizers.
