120-012 0050 VA
Industrial Control Transformers are used to convert the available supply voltage to the voltage that is required to supply industrial control circuits and motor control loads. Some components of a circuit require a very high level of power at start-up which is called Inrush VA. After their initial start-up these components settle down to a lower power requirement for normal continuous operation which is called Sealed or Steady State VA. Some devices can draw up to 10 times the normal operating or sealed current for periods of up to 50 milliseconds upon start up. Control transformers are designed, constructed, and selected to ensure that they provide the output voltage stability needed for trouble free operation of all circuit components.
