0-270V 10A VARIAC

The Variable Transformer provides continuously adjustable AC voltage is an efficient, reliable method of controlling AC voltage from zero to line voltage by amplitude modulation of the AC waveform.

The Variable Transformer, consists of a single-layer winding on a toroidal silicon-steel core. As the control knob is rotated, a carbon brush traverses the winding, tapping off a portion of the total voltage across the winding. The brush is in continuous contact with the winding, and the voltage between turns is always less than 1 volt even in the largest model. In the smallest model it is only about 0.3 volt. The discrete voltage increments obtained as the knob is rotated are always less than the voltage between turns. Since the brush spans more than one turn, the change in voltage is practically continuous. The brush is so designed that excessive heating cannot occur in the turns that it spans.

This Dimmer Dot Variable Transformer has many operating advantages over any other manually operated voltage control devices for alternating current use
