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.

We are manufacturer and exporter of continuously variable Auto Transformers, Variacs and Dimmer stat which operates on a nominal voltage of 240 V A.C & can give output voltage anywhere between 0 – 270 V, by a simple transformer action. The basic Auto Transformer is meant for operation off a nominal voltage of 240 V A.C & can give output voltage anywhere between 0 – 240 V or up to 270 V, by a simple transformer action. Three such Variable Auto transformer when connected electrically in star & mechanically in tandem, became suitable for operations of 415 V 3 Phase A.C. supply & to give output of 0 – 415 V or up to 470 V. Variacs or variable auto transformer is a continuously variable voltage transformer, having a single layer winding on a toroidal core of high grade Steel. In an autotransformer portions of the same winding act as both the primary and secondary winding. the winding has at least three taps where electrical connections are made. One end of the winding is usually connected in common to both the voltage source and the electrical load. The other end of the source and load are connected to taps along the winding. Different taps on the winding correspond to different voltages, measured from the common end. 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. Variable Auto Transformer, manufactured by EnergX is the most useful and effective device for step less, break less and continuous control of A.C voltage and therefore, for control of various other parameters, dependent on A.C voltage. It is ideal controlling device for numerous applications in laboratories and in industrial & commercial fields.

Radiotone Single Layer Roller Contact Vertical Variable Autotransformer (colloquially known as Variac) construction looks like a conventional 3 phase transformer as can be seen from the picture. Speciality of this Variable Autotransformer lies in winding Cu strip of appropriate cross section edgewise. This reduces the length of the column to 1/4 as compared to winding widthwise, thus making it compact. This column is then polished & roller carbons are made to make contact with winding for current collection. Due to circular column construction, a Double Carbon assembly can be provided giving two outputs 180 degrees out of phase (or as it is known + and - type).   Available Models :- 60A 3 Ph, 440V 60A Single Phase 100A 3 ph, 440V 100A Single Phase, 2 Phase

The basic Spectron Continuously Variable Voltage Auto Transformer is meant for operation of a nominal voltage of 240V AC and can give output voltage anywhere between 0 tp 240V, or upto V by a simple transformer action. Three such Spectron Continuously Variable Voltage Auto Transformer when connected electrically in star, and mechanically in tandem, become suitable for operation off 415V 3 Phase AC supply and to give output from 0 to 415 V or up to 470V.
