Specifications:
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 identificationControl Circuit Connection: Deutsch DTMNominal Voltage: 24VDCManual Control: NoEngine Isolation: YesMounting: #10Start Assist: YesStart Isolation: YesAmperage Operating Current When Changing State: <7.0ATerminal Stud Torque: 140 in-lb (15.82 Nm)Continuous Rating: 500AIntermittent Rating: 700A (5 min)Cranking Rating 30 Seconds: 1450A DCCable Size to Meet Ratings: 2x (4/0)Live Current Switching: 300A@12VDCMaster Control Switch Capability: NoSwitching Cycles: 100,000Terminal Ring Diameter Clearance: 1.18" (29.97 mm)Terminal Stud Length: 1.50" (38.1 mm)Terminal Stud Size: 3/8" - 16 (M10)
