The Staco Energy Products 1020B Variable Transformer is an open-unit, adjustable-output transformer in the StacoVT 1000 Series, designed for precise AC voltage control in laboratory benches, test stations, and industrial power setups. The "No Dial" variant indicates it does not include an integrated hand dial for manual adjustment. As part of the 1000 Series Open Units, the 1020B provides a compact enclosure and straightforward wiring that makes it suitable for integration into calibration rigs, test benches, and other voltage-regulation applications where external control or fixed-tap configurations are used.
