Auto Transformers

Auto Transformers  have the capability to supply a varying secondary voltage to an externally connected load. This is used predominantly is applications where various voltage outputs are required such as:

  • Electronics testing centers where continuously varying voltage supplies are required
  • Applications such as power stations which initially require a step up/step down followed by an increase/decrease to match the voltage required by the device at the receiving end
  • Motor starting applications
