TEK Flashers

Tek Flashers
Tek flashers are an ideal substitute for mechanical flashers. They have no moving parts and are designed to mount onto a circuit board. The CMOS timing provides excellent accuracy and repeatability.


Timing Mode

Application of input voltage to the timer starts the time delay. At the end of the delay period, the load is energized. To reset, remove the input voltage to the timer.

  • Digital timing, solid-state output
  • Up to 1 amp current load handling
  • 10 Amps single-cycle surge handling
  • Wide voltage range from 24 to 240 VAC and 12 to 48 VDC
  • .5% Repeat accuracy
  • Time ranges up to 1 second
  • No moving parts
  • Totally encapsulated for protection from harsh environments
  • Board mounting by center mounting post
  • Standard 6.35mm (.250") quick connect blade terminals
  • Optional wire leads
  • 100% Operational testing before shipping

Repeat Accuracy: 0.5% under fixed conditions

Timing Ranges: 0.1 sec. to 1 sec. factory-fixed

Tolerances: Fixed: 10% of nominal time

Temperature Ranges:
