Automatic voltage regulator S099

ACfor alternatoranalog

The new S099 AVR is suitable for every type of alternator, and ensures an high current (45/100 A) in a very low dimension . It is complete with over-voltage protection (displayed from a yellow led), and under frequency protection (displayed from a red led). During the first step the voltage increases proportionally with the frequency, to get the under frequency set normal (the starting point of the low-turns protection trimmer is to 20% less of frequency normal value, and this function can be jumped between 50/60 Hz); and from this point on, also the voltage goes immediately to the nominal value . - Starting from 3,5V minimum self excitation, voltage approaches the nominal value only when the frequency equals the trimmer set value (Hz), and then remains steady onto the nominal value. Under this conditbn, regulatbn is available as a compound with all advantages and precision of electronic regulators. This system moreover allows to charge heavy bads on the main without hampering diesel engine efficiency, both on turbo compressed or old fashbn, and hydroelectric statbns.
