The EMRI 3TX20 V2.0 (No. 1301) is a voltage regulator serving the automatic voltage regulator system of a marine generator set. Its role is to follow alternator output and adjust excitation so that busbar voltage stays at its nominal value while electrical consumers switch in and out. Without this control, generator voltage would drift with load, upsetting motors, electronics and switchboard protection. It is specified with a 20 AT fuse rating. The regulator is offered in new without box condition.
