Speed Controllers - Single Phase
Variable electronic and Transformer type speed controllers for single phase (240V). Also includes switch gear.
Be aware many electronic controllers may make a fan buzz at low speeds (depending on the fan motor) due to the supplied waveform. Transformer controllers do not make this buzzing noise at low speeds as they supply a pure sine wave.
