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
