DewBuster™ Fan Speed Controller

Order Form



FEATURES
  • Fan speed infinitely-variable down to stall speed (minimum speed where fan won't stop).
  • Reducing fan speed not only reduces fan noise but also reduces battery drain.
  • High-efficiency switching regulator does not generate waste heat that might interfere with telescope performance.
  • Controller can deliver 1 Amp continuously (typically 8 fans) but actual Amps will not exceed that specified on your fan’s label.
  • Protective circuitry prevents damage if a wiring fault should ever occur.
OPERATION
  • Turning control knob fully counter-clockwise turns fans OFF and no current is drained from your battery.
  • Turning control knob clockwise turns fans ON at minimum speed and minimal power is drained from your battery.
  • Turning control knob further clockwise increases fan speed but battery drain is no higher than without Fan Controller.
WARRANTY
The Fan Speed Controller is warranted to the original purchaser for 5 years from the date of purchase.


INSTALLATION

For detailed mounting and wiring information, please see the Fan Speed Controller owners manual.

Typical installation is to solder your wires directly to circuit board. If you've never done this before see "Soldering is Easy" beginners guide to learn how easy it is to solder.

For no-soldering installation, you may select Optional Wiring below and the Fan Controller will be prewired with Red and Black wires for power-in, and Yellow and Black wires for power-out to your fan.

I ONLY SHIP TO USA OR APO ADDRESSES. I do not ship international because the Postal Service WILL NOT refund shipping or even tell my why a shipment was rejected by Customs (none of my products are restricted yet they sometimes reject it for no apparent reason). International customers are welcome to ship to a 3rd party in the USA who can then reship to you.
