ABSTRACT:
A regulator for controlling the field exitation current of a generating device when the voltage developed exceeds a preset level and including a first resistor for establishing the level of a base current, a first transistor responsive to the base current for selectively developing the exitation current, a first switching device which is biased on and is connected between the first resistor and the base of the first transistor and a second switching circuit for monitoring the generator voltage and for switching the first switching device off preventing current flow in the first resistor when the voltage exceeds a preset level. The regulator also includes four terminals and a connecting strap configured to permit universal application of the regulator.
