Blue Sea Systems 7633 Automatic Charging Relay

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

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

  • Includes ML-Series Remote Control Contura Switch PN 2146

  • 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
