Enerdrive SI Series 120A 12/24V Automatic Charging Relay (ACR)
The Enerdrive SI Series 120A Automatic Charging Relay (ACR) automatically combines battery banks during charging and isolates them when discharging or starting engines.
Designed for 12V and 24V electrical systems, it supports high-output alternators up to 120A and features dual sensing to monitor charging voltage.
The relay helps protect sensitive electronics by allowing temporary isolation of house loads from the engine circuit during engine cranking. Its hermetically sealed, vaporproof contacts and ignition-protected design make it suitable for installation aboard gasoline-powered boats.
An optional remote LED is available to indicate the ACR's operating state.
