Description
TechnoFan
 
TechnoFan is a compact self contained fan speed controller designed for laser projectors but it would be equally at home in other applications where a fan does not need to run all the time. It features an on board thermistor (with an optional external one available, please contact us for details) and will mount using a single screw. Its compact size 20mm x 24mm means that it can be easily accommodated and is available in versions for 12V or 24V fans. TechnoFan can run multiple fans as long as they are wired in parallel and not series, and they must all be of the same voltage up to a max of 750mA total load.

Benefits include
  • Lower power consumption
  • Quicker warm-up
  • Less fan noise
  • Longer fan Life
  • Better temperature management


The controlled temperature range is 20-70 degrees celcius and is set by a pot on the board, and there are three ranges that determine the difference between 0% duty cycle and 100% duty cycle, which are 20,15 and 10 degrees. This is set by a solder jumper on the PCB but the board is available with the range already selected (note the user can change this themselves - see manual for details).
The default setting is a range of 20 degrees which mean no solder pads are joined.

The board comes complete with a 4 way connector shell and the crimp terminals you need to wire up the unit.
