SS7

SS7 AVR universal voltage regulators are designed to keep brushless alternators the output voltage stable in even when there are consumers load requirement sharp variations . The AVR SS7 controls the excitation current.

Using SS7 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.
