The FlexMod Low Voltage Disconnect unit preserves battery charge and protects battery banks by automatically disconnecting loads when battery voltage drops to a critical level.
Automatically disconnects specified loads when unit senses that vehicle battery voltage is low; automatically reconnects when voltage is restored. Protects vehicles with one battery (or bank of batteries).

Features & Benefits

  • Compact design (4" x 3" x 1" ) unit is waterproof, dustproof and vibration-proof.  Mounts anywhere on a vehicle, even places where road-splash is a problem. Sealed to IP67 standard. 
  • Senses battery voltage and disconnects non-essential loads if level falls below programmed voltage. Automatically reconnects loads when battery is charging.  
  • Eliminates downtime and vehicle breakdown costs due to dead batteries.
