Closed Transition
Each Entelli-Switch 250 microprocessor based ATS
controller requires a Controls Power Supply (CPS) to
apply line voltage to the ATS operator via SCRs. Also
required is power for the Entelli-Switch 250 printed
circuit board and an application of sensing voltage
proportional to line voltage. This is accomplished by the Controls Power Supply (CPS). This method of switching
operator voltage and applying power and sensing voltage to
the printed circuit board isolates the MX250 from the
line voltage, further protecting the controller from
harmful line transients.
