Variacs
Open Frame
Typical variacs supplied by Surplus Sales are open. This one sports a knob and dial plate.
 
Enclosed
Enclosed variac has a metal shield around the winding area for protection of winding. Unit pictured is our (TV) VAR10-140E, which is enclosed and bench mount. Most enclosed units are NOT bench mount.
 
Dual
Dual, or multiple section variacs normally have two or more sections stacked and driven with a single shaft. Our motorized units then have a drive motor to turn the shaft. Unit pictured is our (TV) VAR10-120X2, a dual and enclosed unit. Duals or triple sections can be open or enclosed.
