ML-Series Heavy Duty Automatic Charging Relay

The ACR (automatic charging relay) combines large battery banks for high current charging and emergency cross connect, and isolates under discharge.

• Includes ML-Series Remote Control Contura Switch
• 500 Ampere continuous rating
• Magnetic Latch (ML): ACR draws very low current (<10 mA to monitor terminal voltage) in the "ON" or "OFF" states, and draws moderate current for very short time when changing state.
• 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
• Supports high-output alternators up to 500 Amps
• LED output to remotely indicate when batteries are combined, isolated, in voltage lockout, 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
• Label recesses for circuit protection
• Silver alloy contacts provide high reliability for switching live loads Automatic Functions: Combines battery banks when charging and isolates under discharge
