Variable AC Transformer, Isolated,120/240V in, 0-30V out 25-35Amp

POWERSTAT Variable Transformers provide a simple, rugged method of controlling electrical voltage, current and power. They take in utility line voltage and provide continuously adjustable output voltage. 

POWERSTAT Variable Transformers have three windings: two 120V primary windings which can be connected in either series (for 120V line) or parallel (for 240V line), and an isolated secondary winding rated 0-30V, 25A. A center tap on the secondary allows
15-0-15V operation at 35A.

 

Connections can be made for operation as a source of adjustable low output voltage, a line voltage corrector, or a limited range variable transformer.
