Controls Power Supply (CPS)

Standard and Delay Transition
Each Entelli-Switch 250 microprocessor based ATS
controller requires 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
GE Zenith Controls
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.
