FAN CONTROLLER

DewBuster™ Fan Speed Controller

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.

INSTALLATION

The Fan Speed Controller consists of a circuit board and a control knob. The circuit board may be mounted:

In a small enclosure (not included)
On a plate attached to your telescope (insert control pot through a mounting hole then tighten locknut)
In a recessed area of your rocker box (circuit board has mounting holes for screws)

You may solder your wiring directly to the circuit board (see "Soldering is Easy" beginners guide to soldering) or you may select Optional Wiring on the order form to have the Fan Controller prewired with Red (+) and Black (-) wires for 12V power-in, and Yellow (+) and Black (-) wires to connect to your fan (connectors are not included). See Fan Speed Controller owners manual for complete installation instructions.

WARRANTY

The Fan Speed Controller is warranted to the original purchaser for 5 years from the date of purchase.
