Technipower Type W20G3M, Variac, 3-Gang, Cased. (Inv #7772, 7804) Input: 3 X 120VAC, Output: 3 X 140VAC, 3 X 20A. This versatile unit can simultaneously control three 120V, 20A circuits or can be used to control a single three-phase circuit. (Can be used as a Wye-connected device to control 240V 3-phase circuits. This is possible because the voltage from line to neutral of a wye-connected assembly is the line voltage divided by the square root of 3; thus, in the case of a 240 volt, 3-phase line, the voltage across each coil would be 138 volts. Since 120-volt Variac units are wound for 140 volts across the whole winding, three 120-volt Variac units can be wye-connected if the over-voltage connection is omitted. The load rating of a wye-connected assembly is 3.47 times that of a single unit, or in this case, 69 Amps.) This model is a continuation of the original General Radio Variac series, and is a current model from Technipower, LLC. Weight: approx. 71#. Good used condition, checked, guaranteed. Price: $595.00
