We design and develop precision engineered variable voltage supplies from 0-11 kv. With proficiency in the work domain, we can also manufacture the system with any desired voltage upto 5000 kva as per the specified requirements of our clients. Our featured products are variedly used for special purpose applications and testing.
We present high-precision variable voltage 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 more...

The continuously variable voltage transformer are meant for smooth control of electric power, AC or DC that to on heavy load. Confirming to IS 335, these variable voltage transformer offered by us are basically oil cooled, floor mounting construction and immersed in transformer oil. The cores of the transformer are rigidly mounted on non magnetic frame. The high grade carbon brushes collect the current from side of the windings so that these transformers can handle full variation of the output ranging from 0 voltages to maximum. We make use of standard transformer oil that is filled by the user at site where it is installed. We offer these variable voltage transformer with manual operation and motor operated mode with shaft driven by a high torque low speed drive motor through a gear train. These transformers are know for its efficiency as the time taken for the one revolution is 15 seconds up to 100 Amp models & 30 Seconds for above 100 amp models. We can also provide more...

The three phase manual transformer we offer to customers have a three-legged iron core where each leg has a primary and secondary winding. We make sure that all the coils and winding are connected in proper sequence in order to match the incoming power that helps in maintaining a polarity. Our products are also tested for their cost efficiency, durability and certain other features before they are sent at the clients end. more...
Variable voltage auto transformers is a continuously variable voltage transformer, having a single layer winding on a toroidal core of high grade Cold Rolled Grain Oriented Steel. On one face of the copped winding, along the periphery, a special durable contact surface is made. A specially designed carbon brush slides smoothly on the surface. A contact arm holding the contact brush is fitted to the central shaft and as the control knob is rotated, the carbon brush slides over the winding and taps off a portion of voltage across the winding. Any desired voltage within the maximum range can be obtained by adjusting the position of the brush. The calibrated dial reads approximately the output voltage at no-load, when the input is at its rated value. Rotation of the brush arm by manual of motor drive delivers an output voltage from zero to or above line voltage.
Variacs fitted with voltmeter, ammeter, fuse, switch, pilot lamp etc. can be made in Enclosed type models with extra cost. more...
