Want a simple way to change the voltage on your equipment manually? This RS PRO Variac variable transformer comes with a knob and dial, allowing you to easily adjust the AC output voltage to meet your requirements. It's mounted on a frame with four moulded holes, ready for screwing securely onto the surface of your control panel.
The transformer has a silver-plated commutator to give a smooth, distortion-free output. Its single winding makes it a compact choice, while built-in overload protection helps to ensure your safety. Variac variable transformers are commonly used in industrial environments where controlling voltage is crucial, as well as in audio systems such as amplifiers.
