Blue Sea Systems ML-ACR Automatic Charging Relay with Manual Control

The Blue Sea Systems ML-ACR Automatic Charging Relay with Manual Control is a 500 amp magnetic latching (bi-stable) relay that automatically combines batteries during charging and isolates batteries when discharging and when starting the engine. The manual control switch provides an added level of safety by allowing control with or without power, and offers lock off capability for servicing.

Features:

• Automatically manages the charging of (2) large battery banks
• Allows paralleling of battery banks for emergency starting
• 500 amp continuous rating supports high-output alternators
• Magnetic Latch (ML) ACR draws very low current in on or off states, and draws only moderate current when changing state
• Manual control switch provides an added level of safety allows control with or without power, and offers Lock Off capability for servicing
• Includes ML-Series Remote Control Contura Switch (Blue Sea Systems part no. 2146)
• 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
• Dual Sensing senses charge on (2) battery banks
• LED output remotely indicates 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" stud length accepts multiple cable terminals
• Silver alloy contacts provide high reliability for switching live loads

Specifications:

• Voltage: Specify 12/24V DC
• Amperage: 500 Amps (continuous)/700 amps (intermittent)
• Water resistant rated IP66 protected against heavy seas
• Meets ISO 8846 and SAE J1171 external ignition protection requirements
