Voltage regulator for STAMFORD alternators with auxiliary permanent magnet alternator, PMG.
SS341 AVR voltage regulators are designed to keep brushless alternators the output voltage stable in even when there are consumers load requirement sharp variations . The AVR SS341 controls the excitation current.
Using SS341 AVR the selection of the required voltaje setpoint is achieved in a simple and reliable way; it is also possible to regulate the type of response desired, more or less deliberately, in response to alternator power demand variations.
