If you're looking for a transformer that offers high efficiency when supplying current between circuits, consider this open-style variac transformer from the RS PRO range. It has a robust design and is manufactured from high-quality materials, so it's long-lasting and requires little maintenance. The unit's operating efficiency is enhanced by its low operating torque and low magnetising current. You'll find it in both industrial and domestic settings.

With a silver-plated commutator, the transformer offers smooth linear output, no waveform distortion and an integrated overload capacity to ensure safety. It's regulated by an overvoltage tap and has a continuously variable alternating current output voltage.

You can choose from single or three-phase versions of this transformer with a range of current ratings. This kind of open-style variable transformer can be flash-mounted within control panels, enclosures or process control equipment. It's compliant with RoHS (Restriction of Hazardous Substances) standards for minimal hazardous materials.
