This fully potted device is used when a factory alternator like YANMAR is upgraded to a Safiery 8 pole high output alternator (250A for example)

The device takes the alternator AC pulse output and ratios the pulse output by a selectable set of ratios.

Typically a ration of 4:3 is chosen to go from 6 pole Yanmar to 8 Pole Safiery 250A

The kit includes resistors and a capcitor to clip any noise on the sensor circuit from the alternator.

The unit is fitted in the helm station and requires a 12V power supply
