The MiniTrol is manually adjusted with a percentage-dial 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. MiniTrol 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 makes a positive break. For very small loads, smaller fuses may be used. PL3122 MiniTwin (H1620-2) handles two separate circuits.

The PowrTrol Temperature Controller is a solid-state, proportional-voltage power control. Even though it is small in size, it provides precise manual control of heating mantles, tapes, cords and other resistive loads. The output range is conveniently adjustable from 5-100% of rated voltage. Supplied with lighted on/off power switch, circuit breaker protection, 3-wire load receptacle, and 3-wire line cord with molded plug. 4"w x 4"d x 3-3/8"h. Shipping weight: 2 Lbs.
