Analog voltage regulator ASR

The Latest-technology ASR (Analogic Simplified Regulator) assure an trouble-less use, a precise voltage control and an underfrequency protection. The ASR is a closed loop automatic voltage 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.
