Meccalte AVR ASR

Meccalte AVR ASR

The Latest-technology ASR (Analogic Simplified Regulator) assures a trouble-less use, a precise voltage control and an underfrequency protection.

The ASR is a closed loop AVR regulator system, that controls and keeps constant the alternator output voltage. The output voltage of the alternator is monitored and confronted with a reference signal: the difference between the two is used to control the conduction state of an SCR.

The SCR is controlled by the width of its pulse, and resulting in a rectified DC output which is injected in the rotating inductor of the generator, generating consequently the AC output voltage.

This regulator is specific for ES and ET series.
