Standard Transition
Each MX150 microprocessor based ATS controller
requires a relay/transformer box to apply line voltage
to the ATS operator via coil control relays. 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 relay transformer box. This
method of switching operator voltage and applying power
and sensing voltage to the printed circuit board isolates

the controller from harmful line transients. Two versions
of the R/T box exist depending on the type of ATS
(standard transition or delayed transition).
