This 500A magnetic latching (bi-stable) relay automatically combines batteries during charging as well as isolating batteries when discharging and when starting the engine. The manual control switch (included) provides an added level of safety, allowing control with or without power and offering lock off capability for servicing.
3/8"-16 tin-plated copper studs for maximum conductivity and corrosion resistance.
7/8" (22mm) stud length accepts multiple cable terminals.
500A continuous rating to support high-output alternators.
Allows parelling of battery banks for emergency starting.
Automatically manages the charging of two large battery banks.
Dual sensing - senses charge on both battery banks.
LED output to remotely indicate when batteries are combined, isolaed, in voltage lockout or in start or engine isolation.
Magnetic Latch ACR draws a very low current (< 40mA to monitor terminal voltage) in the 'ON' or 'OFF' states.
Senses charging on two battery banks.
Start Isolation - can be configured for temporary isolation of house loads from the engine during engine cranking to protect sensitive electronics.
