Enerdrive 120A Automatic Charging Relay (ACR) – 12/24V

The Enerdrive 120A Automatic Charging Relay (ACR) automatically shares a single charging source with an auxiliary battery, helping maintain charge across two battery banks. With automatic 12/24V DC voltage ranging and dual-bank charging detection, it is designed for marine battery management systems.

An integrated LED indicates the relay's operating status, while the clip-on cover insulates terminal connections. Side and bottom knockouts provide flexible options for cable entry, and extended studs accommodate multiple cable terminals.

Optional features include Auxiliary Battery Priority, which extends charging time for the auxiliary battery while the engine is running, and a remote LED indicator for monitoring relay status.
