ML-ACR Automatic Charging Relay, 24V

Blue Sea Systems, 7621-BSS, ML-ACR Automatic Charging Relay, 24V DC 500A500 Amp magnetic latching (bi-stable) relay automatically combines batteries during charging and isolates batteries when discharging and when starting engine Features with all optional accessories: Includes ML-Series Remote Control Contura Switch PN 2146 Automatically manages the charging of two large battery banksAllows paralleling of battery banks for emergency starting500 Ampere continuous rating to support high-output alternatorsMagnetic 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 stateDual sensing-senses charge on both battery banksStart Isolation (SI)-can be configured for temporary isolation of House loads from Engine circuit during engine cranking to protect sensitive electronicsEngine Isolation (EI)-can be configured for isolation of two engines while both are running to protect engine electronics and maximize alternator outputSenses charging on two battery banksLED output to remotely indicate when batteries are combined, isolated, in voltage lockout, or in Start or Engine isolation3/8"-16 tin-plated copper studs for maximum conductivity and corrosion resistance7/8" (22mm) stud length accepts multiple cable terminalsSilver alloy contacts provide high reliability for switching live loadsLabel recesses for circuit identification.
