Description
Features
500 Amp magnetic latching (bi-stable) relay automatically combines batteries during charging and isolates batteries when discharging and when starting engine
- ML-Series Remote Control Contura Switch PN 2146 available as a seperate item
- 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 sensingsenses 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
