Blue Sea 7623100 ML ACR Charging Relay 24V 500A w/Manual Control & Deutsch Connector

7623100 ML ACR Charging Relay 24V 500A with Manual Control & Deutsch Connector

500 Amp magnetic latching (bi-stable) relay automatically combines batteries during charging and isolates batteries when discharging and when starting engine.

Features:

• Manual control switch provides an added level of safety allowing control with or without power, and offering LOCK OFF capability for servicing


• Automatically manages the charging of two large battery banks


• Allows paralleling of battery banks for emergency starting


• 500 Ampere continuous rating to support high-output alternators


• Magnetic Latch (ML)—ACR draws very low current (<40mA to monitor terminal voltage) in the "ON" or "OFF" states, and draws moderate current for very short time when changing state


• Dual sensing—senses charge on both battery banks


• Start Isolation (SI)—can be configured for temporary isolation of House loads from Engine circuit during engine cranking to protect sensitive electronics


• Engine Isolation (EI)—can be configured for isolation of two engines while both are running to protect engine electronics and maximize alternator output


• Senses charging on two battery banks


• LED output to remotely indicate when batteries are combined, isolated, in voltage lockout, or in Start or Engine isolation


• 3/8"-16 tin-plated copper studs for maximum conductivity and corrosion resistance


• 7/8" (22mm) stud length accepts multiple cable terminals


• Silver alloy contacts provide high reliability for switching live loads


• Label recesses for circuit identification
