Automatic Charging Relays ML-ACRs

ML-ACR Automatic Charging Relay Manual 12V

7622100
NEW
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
  • 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
MSRP: $307.99

Q: What are the Deutsch parts I need to connect to the Bulk versions of the ML-Products?

A:
These part numbers are also in the installation instructions.



Receptacle Shell DTM-04-6P

Wedge Lock WM-6P

Terminal Pins 1060-20-0122

Sealing Plug 0413-204-2005



Crimping tool needed DTT-20-0

Q: Can I ground to the chassis when installing in a vehicle?

A:
Run the negative wire for the ACR directly to the battery negative terminal of one of the batteries. A chassis ground is often insufficient to allow proper operation.

Q: Do I need a ground wire for the ACR?

A:
Yes, the ACR is an electronic device and needs the ground wire in order to operate. The instructions show an optional switch in the ground wire however the wire is not optional.
