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. these loads consist of a combination of electromagnetic devices such as solenoid operated valves, switches, bells, alarms, and other components such as indicator lights, timers, electronic equipment, and logic boards. some components of a circuit, especially electromagnetic devices require a very high level of power at start up. this start up power requirement is called inrush VA. after their initial start up these components settle down to a lower power requirement for normal continuous operation. this lower operating power requirement 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. most devices have a minimum voltage requirement for normal operation at both start up and steady state conditions. control transformers must be designed, constructed, and selected to ensure that they provide the output voltage stability needed for trouble free operation of all circuit components. Rex control transformers incorporate several features to optimize output voltage stability and regulation when supplying industrial control circuits with high inrush current requirements. to ensure that the selected control transformer is sized adequately and suitable for the application, the following 6 step selection guidance should be followed.
