Superior Electric 9T92A14 Variable Transformer

Superior Electric's POWERSTAT 9T92A14 is a single‑phase, 120 VAC input variable transformer that delivers a continuously adjustable output from 0 to 120 VAC and is rated for about 2.5 A. The output is varied via a CW/CCW knob, providing smooth, repeatable voltage changes across the full range for precise setup, calibration, and experimentation. As part of the POWERSTAT family, this autotransformer offers a rugged, simple method to govern voltage, current and power in a compact form factor, making it a practical bench‑top solution for electronics testing, motor or heater testing, and powering instrumentation that requires adjustable AC supply. This device is well suited for educational, hobbyist, and professional lab environments where straightforward, reliable voltage control is essential.
