SS460

SS460

Voltage regulator for STAMFORD alternators fed from the alternator´s main startor.

SS460 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 SS460 controls the excitation current.

Using SS460 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.
