7.4 Regulation
7.4.1 Using a current output for voltage regulation
You can use a current output and one or more resistors for voltage regulation. That is, you can connect the current output from the
controller to a governor or AVR that requires a voltage input. If the controller signal is lost, the regulator returns to the midpoint. This
makes the system more robust.
INFO
There is no standard governor voltage range, and the documentation for governors is often poor or absent. For that reason,
potentiometers are often used to ensure the correct voltage range.
CAUTION
DEIF recommends field testing the regulator, to ensure that the performance is as required.
