This unique charge relay can be used with heavy duty alternators up to 200A. Its innovating technology based on low frequency switching mode offers stabilized output charge current and protection against reverse voltage to avoid damages to alternators. We recommend keeping at least 30% of the alternator current to charge the starting battery.
