Product Details

The Blue Sea Systems m-LVD Low Voltage Disconnect is an automatic battery protection device that prevents over-discharge by disconnecting non-essential loads when voltage drops too low. Designed for single-battery marine and automotive applications, this intelligent device monitors battery voltage and automatically isolates accessories like stereos, fish finders, and other electronics to preserve enough power for engine starting.

Key Features:

  • Automatic disconnect prevents batteries from discharging to dangerous levels
  • Adjustable disconnect voltage threshold from 11.3V to 12.1V
  • Remote control switch included for convenient helm operation
  • Status LED indicator on both main unit and remote switch provides visual low voltage warning before disconnect
  • Alarm output terminal available for optional audible warning
  • 10-minute override function temporarily delays disconnect for emergency situations
  • Manual OFF position for complete system bypass
  • Rear insulation isolates electrical contacts to prevent accidental shorts
  • Versatile mounting options: surface mount, front panel, or rear panel installation
  • Waterproof construction rated IP67 for temporary immersion protection

The m-LVD is engineered to prevent one of the most common causes of breakdowns—dead batteries from accessory drain. The system continuously monitors voltage and disconnects loads before the battery reaches critically low levels that could damage the battery or leave you stranded. Perfect for boats, RVs, work vehicles, and any application where reliable starting power is essential.

Certifications: UL Marine (UL 1426), ISO 8846 Marine, SAE J1171 Marine, IP67 waterproof rating.
