| FEATURES:
Our variable Auto Transformers have many operating advantages and conveniences over other manually operated voltage control devices for alternating current use 1) Smooth Control: It 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.
