Automatic boat battery coupler RCB-ADJ-120A

The RCB+ Charge Relay is designed to couple a starting battery and the house battery when the alternator is ON either in 12VDC or 24VDC. The coupler has the ability to limit the current flowing from the alternator to the house battery in order to protect the charge of the starting battery. The current limitation flowing to the house battery is fixed (50 or 80A) or can be set with a rotary encoder from 50 to 120A with the RCB-ADJ-120A model. Always keep at least 30% of the alternator current to charge the starting battery. 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 dammages to alternators.
