Key Features: This transformer has strong mechanical strength and short-circuit withstand ability Has a single layer winding on a toroidal core of high grade steel Ideal for over and under voltage testing of electrical and electronic equipment Description: Continously Variable Voltage Auto Transformer is the most effective device for stepless, breakless & continous control of AC voltage & therefore for various parameters, dependent on AC voltage. These Variable Voltage Auto Transformers, consists of a single layer winding on a toroidal silicon-steel core. As the control knob is rotated, a carbon brush traverses the winding, tapping off a portion of the total voltage across the winding. The brush is in continous contact with the winding. The discrete voltage increments obtained as the knob is rotated are always less than the voltage between turns. Since the brush spans more than one turn, the change in voltage is practically continuous. As output voltage is continously variable, Variable Voltage Auto Transformers are rated in terms of current that can be drawn from the output. The basic Continously Variable Voltage Auto Transformers is meant for operation from a nominal input voltage of 240 V I ph AC & can give output voltage anywhere between 0 to 240 v or 0 to 270V AC by simple transformer action. Three such Variable Voltage Auto Transformers connected electrically in star and mechanically in tandem, become suitable for operation from a nominal input voltage of 415V 3Ph AC and can give output anywhere between 0 to 415V or 0 to 470V. Rating Available: 4 Amps- 1600 Amps

VARIAC is a continuous Variable AutoTransformer, having a single layer winding on a Toroidal Core( Donut-Shaped )  CRGO Stamping (  high-grade Cold Rolled Grain Oriented  steel). On one side of the copper winding, a special durable contact surface is made.  A contact holder arm  with specially selected high grade carbon brushes  slides smoothly on this surface over the winding and taps of a portion of voltage across the winding. Any desired voltage within the Maximum range can be obtained by adjusting the position of the Brush.   High grade CRGO stamping is used for making Variac Coils. Purity of copper is 99.99% used for winding the Variac coils. Very smooth & step less voltage control. Easy Installation & Connections. Temperature remains low. Virtually maintenance free High grade carbon brushes are used Wide range of current rating 4 Amp. To 1250 Amp. High Efficiency Power factor distortion & wave form is negligible.

Radiotone 0.5 A, 0.75 A, 1.2 A Single Layer Variable Autotransformers (colloquially known as Variac) are very small in size (82 mm Dia) Variable Autotransformers.  In same size we can also make from 0 to 25V at 5A or 0 – 50V @ 3A and for 400 Hz applications. Radiotone 0.5 A, 0.75 A, 1.2 A Single Layer Variable Autotransformers (colloquially known as Variac) are used in Instrumentation, HV Testers & Aviation (400 Hz).  All the models are coated for physical protection as shown in the picture.  We use Roller brushes for very smooth long lasting & arc free contact. 

We specialize in the manufacture of high current rated coils. The commutator surface of our coils is machine processed and hence very uniform and smooth. This is very important for proper collection of current by the carbon brushes thus reducing the heat generated. Our standard coils are 100 Amp, 150 Amp, 200 Amp. Using these coils we manufacture oil-cooled variautos from 100 Amp 3 Ph to 1200 Amp 3 Ph capacity (415 V input and 0-470 V variable output). In high current rated models we use multiple coils with properly rated balancing coils to achieve the rated current. Based on the calculations of cooling area appropriate no. of radiators &fins  are used. These variautos are generally motorized with geared mechanism. We also cater to tailor-made requirements.
