When cranking engine, vehicle electronics systems are in standby to prevent data loss, the heavy current draw of cranking combined with a full electronics suite can cause voltage drops severe enough to upset memorized settings. By delaying the equipment activation until after the engine is completely started, the on/on delay timer prevents data loss and vehicle down time.

  • Emergency override switch provides a convenient way to restore power to your equipment by holding the button in.
  • Electronic equipment protection system, computers, GPS, AVL and etc.
  • Low / High voltage detection and shutdown.
  • Automatic On/Off - no user intervention required
  • Prevents battery deep discharge/li>
  • Programmable with external DIP switch for selecting and adjusting time delay
  • Built-in diagnostic red LED indicates timing functions active when flashing
  • Engineered electronically for reverse polarity protection
  • Potted compound construction. Solid state, sealed against vibration and moisture.
  • Easy external connection with .250 male tab mating with .250 female disconnect
  • Delay time range:from 5 seconds to 120 seconds (2 minutes). Tolerance plus (+) or minus (-) 10%
  • Allow 3-5 seconds for delay on break at ignition switch connection for delay activation
  • For installation, connect the red wire (+) to a master switch and the black wire (-) to the battery negative post. Connect the blue wire to fuse block (AM/FM radio) or cigarette lighter.
