Automatic boat battery coupler RCB-ADJ-120A

With the increasing use of Lithium batteries (LiFePo4) for on-board electrical systems, compatibility between different battery types has become a major issue. Indeed, the cohabitation between starter batteries, often lead-acid, and lithium batteries for service requires specific management of energy flows, particularly during alternator operation. RCB+ smart coupler relay responds to this challenge by providing an efficient and secure connection between these two types of battery. The device is capable of managing the current coming from the alternator, either 12 or 24VDC, up to 200A, by limiting it to the service battery, while protecting starter battery charge. One of the RCB+’s key features is its ability to limit the current flowing between the alternator and the service battery. Thanks to a setting wheel for the adjustable version, the user can adjust the current between 30 and 120A, guaranteeing flexibility according to the on-board system’s needs. It is recommended to retain around 30% of the alternator’s capacity for the starter battery; for example, for a 110Ah alternator, the limit could be set at 70A for service bank. This fine-tuned management preserves the alternator from overload while optimizing the battery charge (see illustration below). Compact and lightweight this unique compact relay is designed to be used in harsh environment. Its innovating technology based on low frequency switching mode offers stabilized output charge current and protection against reverse voltage to avoid damages on the alternator. On the RCB-ADJ-120A model the black selector wheel of the encoder can be removed for safety or maintenance reason.In some cases RCB+ can replace a
