MCE123A
Auxiliary Controller
The SAUER-SUNDSTRAND MCE123A Auxiliary
Controller provides, in open loop, a "reverse proportio-
nal" control signal to the Electrical Displacement Control
(EDC). This signal is proportional to the measured
frequency input to the Controller from a speed sensor.
The Controller is designed so that with increasing
speed, the output is reduced.

BLN-96-9209-2E
The electronic MCE123A converts the frequency signal
to a proportional DC voltage.
Depending on an adjustable control characteristic
(see figure 1) the output current value is "reverse
proportional" to the frequency signal.
