Automatically disconnects non-critical loads from a battery when the battery voltage falls below a predefined threshold. Automatically reconnects the loads to the battery when it is being charged which prolongs battery life by preventing premature damage. No more stranded vehicles! Avoid the time and expense of getting your vehicles towed. The SureStart LVD ensures that there is enough power to start, and saves the batteries on vehicles that aren’t used every day.

Features

  • Overcurrent, short-circuit and over-temperature protections offer safe and reliable operation.
  • Eliminates contact wear and extends service life to ≥1,000,000 On-Off cycles.
  • Resistant to vibration and mechanical shock.
  • Draws minimal quiescent current of 2mA.
  • Pre-disconnect warning is provided by a visual or audible alarm (sold separately).
  • Built-in “snooze timer” allows one hour override (factory programmable).
  • Automatically disconnects non-critical loads from a battery when the battery voltage falls below a predefined threshold.
  • Automatically reconnects the loads to the battery when the battery is being charged.
  • Automatically prevents the loads from disconnecting during starting.
  • Manual override option permits a user to make or break the connection, regardless of the battery voltage. (Switch sold separately.)
