R222 - Leroy Somer

The 200 series regulators are shunt regulators, that is they tap off field current from the alternator, which control the voltage or the cosíåÛåÎÖ 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.
