The Fuji Electric Hirex-85-3 C is an automatic voltage regulator for the generator control system on board ship. It holds the alternator’s output voltage steady by governing excitation as the electrical load on the switchboard rises and falls. The unit is rated DC 200 V and AC 450 V, with a DC current rating of 15 A, and was made in Japan. It is supplied in Used condition. Motors, pumps, lighting and navigation equipment fed from the main switchboard all depend on stable generator voltage, and this regulator sits at the centre of that control loop.
