* We have fused the power cord at 7 amps even though the controller is capable of amperages of 5 amps per channel (10 amps total). We do not recommend replacing the power cord fuse with a larger fuse as the power input socket is not rated for a higher amperage.

Dewminator Controller

Our new mid-level controller is the perfect choice for those who are budget conscious, but still want more than basic features. Dewminator features 4 individual adjustable heater ports and dual DC Accessory Ports that can power other 12V equipment. Product Features: Heavy-Duty, individually adjustable power output for up to 4 heaters. 2 DC Accessory Ports 15 Amps total power (max 7 Amp with Cigarette Lighter Plug). Dimmable lights! In fact, after 20 seconds, they shut-off! Turning any knob will "wake-up" the lights again. User Changeable Cord. Cord Management - Power other devices using the 2 DC Accessory Ports. For example, our 12V USB Hub. Low Voltage Cut-Off - A Kendrick Standard that saves your battery from permanent destruction. Disable Low Voltage Cut-Off. We don't recommend it, but if you want to drain your battery beyond repair it is now possible.

Anderson Power Pole Option: This is a “kit” that you can install on your power cord (replace the cigarette plug). To use this kit, you also need a 12VDC power source that uses Anderson Power Poles, such as Kendrick Portable Power Packs and Power Panels. For convenience, we offer 2 Anderson Kits that include the Red & Black plastic shells and 2 metal contacts. The “pre-welded” kit permanently bonds the plastic shells in the standard Kendrick plug orientation. If you are connecting to a non-Kendrick power source, and are unsure of the plug orientation you need, purchase the "non-welded" model. Extra Power Cords are available.. The controller does include a power cord, but some people like a spare cord and they are available for purchase. The power cord is the same used on our DigiFire FX-PRO Controller and can be found in the DigiFire FX-PRO section below.

DigiFire FX-PRO - Temperature Sensing Features Temperature Sensing control for 2 of the 4 heater ports. Heaters are only powered when the temperature of your optics reaches the level you choose. It works on the difference between Ambient Air Temperature and the temperature of your optics. Choose a setting that is 0-10 C° Prevents unnecessary over-heating (which degrades image quality) Saves battery power Traditional "Duty-Cycle" settings are also available on all 4 heater ports Sensors included: 2 - 1 of these is the Ambient Air Temperature and the other is the Optic Temperature Sensor. Additional Sensors are optional. If you want to use Temperature Regulation on a 2nd optic (telescope), order an extra Temperature Sensor. Anderson Power Pole Option: This is a “kit” that you can install on your power cord (replace the cigarette plug). To use this kit, you also need a 12VDC power source that uses Anderson Power Poles, such as Kendrick Portable Power Packs and Power Panels.

Premier Controller

Coming Summer 2024 The next generation of Observatory Class Dew Controller will be much more than a Dew Controller. The new controller has been on the drawing board for several years now and has evolved to include a number of new capabilities that go well beyond dew control alone. The feature list is still top secret, but we can promise that it will have everything that you would expect to see in a professional observatory at a price point that will be affordable to amateur astronomers. Take note that the photo seen here does NOT show some of the features that will included in the final production version. Some features that we can talk about now: It is smaller and lighter than our original Premier Controller It has the same features as the original Premier Controller plus many more. Of course, it will have:. 4 heater ports Sensors for temperature: ambient, dew point (including barometric pressure), optics Remote Control via local computer connection In all, this 1 device will replace as many as 5 separate devices. Still TOP SECRET, but worth waiting for! If you want to be notified when the controller becomes available, please join our Premier Controller Notification List. This will be a one time only mailing and you will not receive other product notifications from us.

 

 

How To Use The System

We recommend that you put your heaters in place at the beginning of an observing session and turn your controller on right away. If you are using Premier Heaters, or heaters for Newtonian or RC Telescopes, we recommend a controller setting that represents about 20 to 40% If you are using FireFly or MICRO FireLite Heaters, we recommend a setting of about 60 to 80%.

If moisture has already condensed on your optics, we recommend covering the optics, turning the heaters on high and waiting 20 to 30 minutes. Once the moisture has cleared, lower your controller setting and resume observing.

 

Power Requirements

Our dew control systems require 12 volts DC. If you are using a battery to run the system, we recommend at minimum, an 18-amp hour battery. But when you have access to 120V AC Power, our AC-DC Power Supplies allow you to generate 12V (13.8V nominal) from a 120V wall plug.

We offer 2 models of AC-DC Power Supplies

A 12 Amp Linear Power Supply with a 5V Charging Port. For most astronomers, this is a great choice.

A 25 Amp Switching Power Supply with cigarette plug, Banana Plug, and Anderson Power Pole. For REALLY BIG rigs that use big dew heaters, cooled CCD Cameras, and lots of other 12V Accessories, 25 Amps is a better choice with plenty of power and room to spare.

We also build portable 12 volt power packs and offer other power solutions that can be used with all your astro equipment that is used in the field. See Power Packs for more information on the power systems we offer.

How much power do you need? Add up the current draw from all connected equipment and then multiply by at least 2. Generally, you want a power supply that can deliver twice as much power as you think you might need. Otherwise, an overworked PS is going to fail or even get excessively hot. NEW Big-Honkin 25 Amp Power Supply (110VAC or 220VAC)! Big mounts, cooled CCD Cameras, Dew Heaters use a lot of juice. 25 Amps is enough power to run just about any device you would ever need.
