The AVK Cosimat C2 (Cosimat C2 1) is a voltage regulator from the automatic voltage regulator family, used in the excitation circuit of marine generator alternators. It adjusts exciter field current so the alternator holds its output voltage under changing electrical demand. Two voltage ranges are marked on the unit: U500 for 250-500 V AC and U250 for 90-250 V AC. It was made in Germany. Condition is Used. On board, it serves as the voltage control element between the generator and its excitation system.
