The Kendrick Dew Remover System is centered around the controller. It is a compact, lightweight duty cycle switch that is fused and reverse polarity protected. The power cord is 6' long and has a cigarette lighter plug. There are four RCA jacks on the controller to plug your heaters into. With the addition of an RCA splitter cord, 5 to 6 heaters can be attached. This would allow the operator to use heaters for the main objective, both ends of a finder or guide scope and a telrad.

The box is constructed of aluminum painted black and includes a red LED to indicate whether your system is receiving power. The power output from the controller can be varied from 40% to 100%. As the controller is a duty cycle switch, it controls the power getting to your heaters by shutting it on and off many times each minute. When the controller is set on low, the heaters will continue to draw the same amount of current, only 40% of the time. Low to medium is the recommended setting for most observing conditions. The controller is not a transformer and must be supplied with 12VDC. The controller is supplied with Velcro that will allow it to attach to your tube assembly, mount or tripod at your discretion. Box dimensions are 3.5" x 2.25" x 1.25" (1.75" with knob).

The fuse for the controller is located in the cigarette lighter jack and can be accessed by pushing in the metal pin on the front of the plug, turning it counterclockwise and then pulling it out. If the red LED fails to come on, this should be the first thing you check.
