Blue Sea ML-ACR ML Series Automatic Charging Relay
PART NUMBER: 8-27620
Description
ML-ACR Automatic Charging Relay - 12V DC 500A - 7620
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.
Features
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.
