    • We have carved a niche as one of the dominant Variac Variable Transformers Exporters from India. VARIAC Auto Transformers 1 Ph. (Closed / Open type) are designed to give output voltage of 260-270 Volts for the input voltage of 240 Volts. 3 Phase VARIAC Auto Transformers are designed to give output voltage of 470 Volts for input 415 Volts. These are available in manual and motorized operating type. Variac Auto Transformers are continuously variable voltage auto transformer, having a movable carbon tip, fixed to a brush-arm sliding on a silver plated commutator. Rotation of the brush-arm by either manual or motor drive, delivers-an output voltage from zero to or above line voltage. Variac conforms to I. S. 5142 of 1969. SALIENT FEATURES: RUGGED CONSTRUCTION: Variac transformer is designed for heavy duty trouble-free operation. All components are designed to give maximum life to the unit under extreme operating conditions. Except, for carbon tips, no other part needs any specific maintenance. Even carbon tips do not require to be changed frequently. This practically makes the VARIAC maintenance free electrical equipment. EXCELLENT REGULATION: The drop in voltage from "no load to full load" is minimal in Variac Auto-transformers. HIGH EFFICIENCY: Careful copper, core selection and design assure the user of low watt loss, as compared to other types of controllers. NO WAVE FORM DISTORTION: VARIAC provides an output voltage wave-form, which is a faithful and distortion less replica of the input voltage wave-form. SILVER PLATED COMMUTATOR: A special silver plating technique is used on the commutator enabling it to withstand high overloads and maintain constant contact drop. It also ensures smooth operation, long life and increased resistance to corrosion. LOW OPERATING TORQUE: A glass smooth commutator, special sintered bushings for the shaft and perfect assembling of the coils, results in low operating torque for all Variac Auto-transformers. SMOOTH AND LINEAR OUTPUT: As voltage between turns is small and as the brush-arm is in constant contact with more than one turn, harmful sparking is avoided and output voltage can be set very easily to a fraction of a volt from zero onwards by rotation of the knob. LOW MAGNETIZING CURRENT: By using an adequate section of high quality grain oriented silicon steel, the iron losses in Variac, are controlled to the minimum, The no-load current in all Variac transformers, is invariably less than 5% of the rated current. NEGLIGIBLE MAINTENANCE AND TROUBLE-FREE LONG LIFE: Variac has been carefully designed. No special care has to be taken to maintain Variac Auto-transformers in-normal- working environments. The only components needing inspection and maintenance are the carbon tips and the commutator. Timely replacement of carbon tips and cleaning of the commutator surface of foreign particles and accumulated dust, will ensure a considerably long, maintenance-free, and uninterrupted life to the unit. Normally Variac Auto-transformers upto 28 Amps. are offered in air-cooled or oil cooled construction and models of 40 Amps. and above, are offered in oil-cooled construction in very special cases, Variacs of 40 Amps. & above can be offered in air-cooled construction. This is possible due to the new paralleling techniques adopted by us.

    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

    • Dimmerstat is registered trademark of AE for continuously variable voltage auto-transformer. It is the most effective device for step less, break less & continuous control of AC voltage & therefore for various parameters, dependent on AC voltage.The basic Dimmerstat is meant for operation from a nominal input voltage of 240V AC & can give output voltage anywhere between 0 to 240V or 0 to 270VAC by simple transformer action. Three such Dimmerstat 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.Resin moulded Dimmerstat is basically a variable Voltage Auto-Transformer which is partly or fully Moulded in Reinforced Polyester Resin. This has adjustable spindles which allow easy assembling of flush, table or Motorized Type in single or three phase models. These models are designed up to 120% continuous load.Features Simple, rugged construction. Coils made from high grade CRGO Silicon Steel & 99.9% pure Electrolytic copper. Output voltage variation is smooth, continuous, break less & linearly proportional to angular rotation. High efficiency. Negligible waveform & power factor distortion. Excellent short time overloads capacity. Remote operation possible by motorization. Wide range of current ratings. High quality carbon brush used for current collection.

    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.
