The 200 series regulators are shunt regulators, that is they tap off field current from the alternator, which control the voltage or the cosÌ_åÛåÎÌÐ of the alternator by adjus- ting the field current in the exciter field coil. They can operate alone or with a short circuit corrector, also called a parallel booster in the event that a short circuit current is necessary or when large auxiliaries need to be started. They are completely encapsulated and are suitable for fitting inside or outside the machine.
