Designed to protect vehicle batteries from over discharge, Lind Electronics introduces the Lind Shut Down Timer (SDT). The Lind SDT is programmed to automatically turn off electrical loads at a preset time after the vehicle's ignition is shut off. Unlike timers that use inaccessible switches buried within the timer, the Lind SDT can be easily set with a screwdriver. Unique to the Lind SDT is a rapid testing function that enables operators to know immediately that the timer is set and operating properly.
