Save valuable time on maintenance with this open-style variac transformer from the RS PRO professional range. This extremely efficient open-style variac transformer is used to supply electricity between circuits. It's sturdily built from high-quality materials, so will be long-lasting and require little attention once installed.

A low operating torque and a low magnetising current contribute to this transformer's efficient operation. It comprises a silver-plated commutator offering a smooth linear output, no waveform distortion and an integrated overload capacity for safety. There's a continuously variable alternating current output voltage and an overvoltage tap for regulation.

You can find this transformer in single or three-phase versions with various current ratings. It's suitable for flash mounting within control panels, enclosures or process control equipment. You'll often find these transformers in the home and businesses. It contains minimal levels of hazardous materials so it's RoHS (Restriction of Hazardous Substances) compliant.
