The offered transformer is used to provide continuously variable voltage for various heavy industries and commercial sectors. This transformer is fabricated under the supervision of our well-versed engineers by utilizing the best quality raw material as per the set industry norms. Our clients can avail this Auto Variable Transformer in various specifications at market leading price. Features: VARISTAT continuously variable Auto Transformers have many operating advantages and conveniences over other manually operated voltage control devices for alternating current use Smooth Control: The VARISTAT can be set to any output voltage within its range. Output voltage is continuously adjustable from zero to maximum. Small Size: The variable Auto Transformers is much smaller than any other type of control of equal rating. Better Efficiency: Very low losses under all loud conditions. Toroidal VARISTAT have low-loss grain oriented strip wound cores. Better Regulation: Output voltage is substantially independent of  loud. Linear Output Volts: Output Voltage varies linearly with angle of rotation of control knob. Temperature rise: Less than 50 deg.C for continuous duty. Advanced Design: Excellent electrical specification is matched by rugged compact construction. Brush replacement is simple and convenient.TwoThree or more units can be ganged on one shaft for seriesparallel or three-phase operation. Long Life: When used correctly the VARISTAT has a very long operating life.The life of a VARISTAT is essentially the same as that of any standard fixed ratio power transformer. Indian Standards: All VARISTAT unit conform to I.S.S. 5142-1969 Easily Read Dials: Dials are single - reading with large clear numerals easy to read at a distance. Wide range of models: VARISTAT are available in a wide range of models to suit various requirements. These include Open - for panel mounting purpose Enclosed - Suitable for table mounting Portable - with or without meters Oil Cooled - for increased ratings Double Wound - Where the primary is isolated from the secondary prominant for manufacturer of servo-control voltage stabilizer High Frequency - for various louds Special Voltage - 120v 240v 400vetc. VARISTAT APPLICATION Supply Voltage Correction Boosting of low lines and line voltage stabilisation either manually or automatically in automatic voltage stabilizers Control of D.C. voltage and current through rectifiers. Control of rectifiers in electroplating battery chargers etc. Motor speed control in textile machines blow moulding machines injection moulding machinesprinting and packaging machineries etc. Testing and calibration of voltmeters ammeters wattmeters power-factor meters etc. Voltage and current control in development and experimental  works Heating control of ovensfurnaces infra-red heaters etc. in production and experimental works Lighting control in theaters auditorium hotels restaurant photographic studios and dark-rooms reading housesetc. SPECIFICATIONS Input Voltage: The voltage that should be applied to the input terminals to make the dial calibration correct is 240v 50Hz 415v 50Hz Output Voltage: The output voltage from the varistat is continuously adjustable from zero to 12.5% above the line voltage (i.e. 270V or 470V). The dial reads the approximate voltage. No load current: Less than 2% of full load Construction: Both single and three phase units are supplied enclosed in sheet metal covers unless asked  for open type construction for panel mountingoil cooled units are supplied in sheet-metal tanks with or without cooling radiators. Current ratings: (single wound type) Click here for more details.
