(TV) 033-6565

Staco heavy duty motorized variac. 12 vdc motor control. Unit removed from service in excellent condition. Variac has been load tested. Variac is 6-3/4" diameter. Our variacs are the highest quality, MADE IN THE USA!. Not poorly made imported copies.

Input: 90 - 132 vac
Output: 0 - 120v @ 20 amps
Dimensions: 7-1/8"H x 8"W x 11" deep
Weight: 35 lbs

Although designed for 12 vdc operation, the motor will run at lower voltages with correspondingly longer rotation times. Viewed from the shaft end, rotation is clockwise with the red lead to positive, black lead to negative. Connections must be reversed to reverse rotation. There are no limit switches to stop the motor at the end of rotation. Power must be removed to stop. Rotation time may vary slightly in each direction. Motor draws less than 200 mA.

The voltages and approximate times are listed below:

Applied voltage	Rotation Time
5v	10 seconds
7v	6 seconds
9v	5 seconds
11v	4 seconds
13v	3 seconds
16v	3 seconds
