The Variac V10 is a single-phase variable autotransformer that delivers continuously adjustable AC voltage output by rotating a control knob. Rated for 10 A on both primary and secondary windings, it accepts 115 V AC input and produces 0–130 V AC output across 50–60 Hz operation. The single-layer toroidal core design achieves efficiency exceeding 98% with zero waveform distortion, making it ideal for precision voltage control in test, calibration, and laboratory environments.
