Variable Temperature Control Transformers

(2)
The operator manually adjusts this controller, which has a percentage-timer design and no sensing element. It regulates mantles, tapes and cords, as well as small furnaces, ovens, hot plates, dies and other applications requiring stepless control. This controller may also be used on any non-inductive loads to its rated capacity. It proportions the operating voltage to the load from 5 1/2% to 100% of the time according to the preset dial position. When turned off, it effects a positive break. For very small loads, smaller fuses may be used. A pilot light is connected across the output side of the controller, indicating power to load. With the desired temperature determined on the initial run, a simple dial setting controls repeat operation.
