ML-ACR Automatic Charging Relay with Manual Control - 24vDC 500A

The Blue Sea ML-ACR Automatic Charging Relay intelligently manages dual battery banks on 24VDC systems, automatically connecting them during charging and isolating them during discharge to prevent drain. With a robust 500-ampere continuous rating, it handles high-output alternators without compromise. The magnetic latch design draws minimal current—under 40mA—to monitor terminal voltage in both ON and OFF states, maximizing efficiency. Manual control override allows emergency paralleling for starting power when needed. Ideal for marine vessels, RVs, and off-grid systems requiring reliable, hands-free battery management.
