Controls Power Supply (CPS)

Standard and Delay Transition

Each MX150 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 MX150 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 MX150 from the line voltage, further protecting the controller from harmful line transients.
