Technical Specifications
Variable Auto Transformers
Delivers smooth, continuously adjustable AC voltage control for precision laboratory and industrial processes.
Overview & Engineering Design
Commonly known as Variacs, our Variable Auto Transformers provide a continuously adjustable AC voltage output from zero to line capacity without distorting the sine wave. Ideal for precision testing, calibration, and temperature control systems. Our engineering standards ensure premium material selection, including high-permeability grain-oriented (CRGO) steel laminate cores and double-insulated electrolytic copper windings, designed for low core losses and continuous operational uptime.
