The Kendrick dual channel dew heater controller is used with Kendrick dew heater strips, to warm your telescope, spotting scope or camera lens, eliminating fogging or dewing. Its very simple, easy to use, compact, and lightweight. There are 4x RCA jacks on the controller into which you can plug your heater strips. For example, you can keep the main objective lens of your small telescope or camera, an eyepiece, a finder scope and a guide scope all condensation-free!
Whether youre an astronomer or photographer, you can keep your optics free of fogging in damp cold conditions.

4x 12 VDC power RCA outputs to clear your telescope or DSLR lens of dew.
2x separate control knobs, each knob controlling over a 0% to 100% range.

3x LED indicators, one for each channel showing if its active.

Compact yet tough 3 x 4 x 1.35 plastic case, weighing 190 grams.
Fused male cigarette lighter plug on a detachable 6' long.
Power cord can be connected to a 12v car cigarette lighter plug or rechargeable 12V DC battery.
The Kendrick standard dual channel dew controller uses MOSFET transistors in the controller circuit board and each power output so there are no voltage drops. This gives you the best possible performance out of your heater strips.
In addition, the Kendrick controller is reverse polarity protected. The controller is RFI (radio frequency interference) free, an absolute necessity if you are digital imager. Supplied with Velcro strips to attach to a telescope or tripod.
How the Kendrick dew system works:
The power output can be varied from 0% to 100% with Pulse Width Modulation duty cycle switching. The power going to your heaters is regulated by turning the power on and off many times each minute. For example, when the controller is set to the 50% point, the heaters draw the same amount of current whenever they are on, but they are only on for 50% of the time.
