ML SERIES 12V 500A AUTO CHARGE RELAY

ML-ACR Automatic Charging Relay with Manual Control – 12V DC 500A

BS-7622:

The ML-ACR (Automatic Charging Relay) and ML-RBS (Remote Battery Switch), when paired, offer complete battery management of large battery banks with the push of a button. In addition to automatically sharing the charge from an engine’s alternator between the start and auxiliary battery, the ML-ACR control switch provides momentary battery combining to assist with starting in the event of a low engine battery. Multiple remote battery switches can be easily connected to the ML-ACR with the optional Paralleling Link Bus for a complete remote battery management Subsystem.

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
