Variable Autotransformer

The importance of continuously variable voltage in Electrical Engg. Works cannot be overemphasized, ARKAY 'VARISTAT' are made to make such continuously variable voltage most easily available.

SPECIAL FEATURES OF VARIABLE AUTO TRANSFORMERS:

1) Smooth Control: The VARISTAT can be set to any output voltage within its range. Output voltage is continuously adjustable from zero to maximum.
2) Small Size: The variable Auto Transformers is much smaller than any other type of control of equal rating.
3) Better Efficiency: Very low losses under all loud conditions. Toroidal VARISTAT have low-loss grain oriented strip wound cores.
4) Better Regulation: Output voltage is substantially independent of loud.
5) Linear Output Volts: Output Voltage varies linearly with angle of rotation of control knob.
6) Temperature rise: Less than 50 deg.C for continuous duty.
7) Advanced Design: Excellent electrical specification is matched by rugged, compact construction. Brush replacement is simple and convenient.Two,Three or more units can be ganged on one shaft for series,parallel or three-phase operation.
8) 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.

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.
