When battling dew, work smarter rather than harder. Your battery life is increased by the Smart DewHeater and Controller 2x by maximizing electricity for up to two dew heaters.
Your optics are warmed just enough by the controller to prevent dew accumulation. The controller continuously collects and analyses data.
With its two ports, the Smart DewHeater and Controller can simultaneously control two dew warmers. One port can be used to warm your optical tube, while the other can be used to warm another optical tube, a guiding scope, an eyepiece, or any piece of equipment. In order to power another 12V DC device, such as your mount, the controller also has an extra 12V DC output connector.
The Celestron Dew Heater Rings, which include a built-in thermistor to provide temperature readings of the corrector lens, are perfectly compatible with the Smart DewHeater and Controller. Thermistor for Smart DewHeater Controllers from Celestron must be added in order for third-party dew heater bands or straps to work (sold separately).
A powerful microprocessor at the controller's core compiles data from the sensors, makes calculations, and automatically modifies your dew heaters. Using a built-in environmental sensor and thermistors, the controller keeps track of the temperature and humidity of the surrounding air as well as the temperature of the heaters.
The Smart DewHeater and Controller 2x are accessories that can be used independently. You can also link it to the hand controller for your Celestron telescope or your PC if you want to view data from the controller and make manual adjustments. The controller is compatible with Celestron CPWI telescope control software, which comes with every Celestron mount, as well as NexStar+ or StarSense hand controls with the most recent firmware.
The Smart DewHeater and Controller 2x can handle a maximum power of 120W (10A max current @ 12V DC) and is powered by a 12V DC battery (like our PowerTank Lithium Pro or PowerTank 17).A 12V DC output connection is also included on the controller. This second port can be used to power an additional device, such as your mount. You can then use that source to power the entire system. If the input or output current draw increases, resettable electronic fuses prevent harm.
NOTE: The controller may be operating close to its power limit if you are utilizing two dew heaters in high dew conditions and powering a 12V DC device.
In this situation, a single PowerTank Lithium Pro or PowerTank 17Ah won't be able to power your setup throughout the night; you'll need a battery with a higher capacity or numerous batteries.
Unique Industrial Design
The heavy-duty metal enclosure is a feature of the Smart DewHeater and Controller 2x. The controller's internal cooling fan shields the circuitry.
The Bridge, is located on top of the controller and houses the device's status LEDs and environmental sensors. Additionally, aids cable management. The temperature and humidity sensors are located here, away from the control panel and other parts that could produce heat. Our sensors don't need any extra cords, in contrast to competing devices, to get precise readings.
The bridge's LED lights show the device's status right now. If the controller is consuming more current than your power source can offer or if the battery needs to be recharged, the LEDs will alert you. If the sky is cloudy or gloomy, you can turn the lights down.
The integrated dovetail clamps let you mount the Celestron Smart DewHeater and Controller 2x on your CGE or CG-5 dovetail.
Use the provided strap to attach the controller to a tripod leg if you prefer.
