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.
Controls Power Supply (CPS)
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.
