Optimize your setup and extend battery life with this powerful controller, designed to manage up to four dew heaters while powering your entire telescope system. The Smart DewHeater analyzes real-time data to keep your optics free of dew by providing just the right amount of heat. It features four dedicated dew heater ports, four 12V DC output ports for powering accessories like mounts and cameras, and three powered USB 3.2 ports for easy device management.

The Celestron Smart DewHeater and Power Controller 4X uses an advanced microprocessor that continuously monitors environmental conditions, such as temperature and humidity, as well as the heaters' performance, adjusting the heat output accordingly to prevent dew from forming. This results in power-efficient operation, extending your battery life during long observing or imaging sessions.

You can control up to four dew heaters simultaneously, perfect for a range of accessories like optical tubes, guide scopes, and eyepieces. The controller also offers full power management for your entire telescope system, including mounts, focus motors, and cameras, all from one source.

In addition to dew heater management, the Smart DewHeater and Power Controller 4X provides four 12V DC output ports for powering other telescope devices. One of these ports offers variable voltage (3V-12V), ideal for devices like DSLRs or focusers that require different power levels. The controller also includes three powered USB 3.2 ports for connecting your devices to your computer, significantly simplifying cable management. You can control the power to each USB device individually via Celestron’s hand control or CPWI software.

The Smart DewHeater and Power Controller 4X is designed to run on a 12V DC battery, like the Celestron PowerTank Lithium Pro or PowerTank 17. With a maximum power draw of 240W (20A max), it can handle a variety of connected devices. However, if you're running multiple dew heaters and 12V accessories in heavy dew conditions, consider using a higher-capacity battery or multiple power sources to ensure uninterrupted operation throughout the night.

With a heavy-duty metal housing and an integrated cooling fan, the controller’s electronics are kept safe and cool, even during extended use. The bridge atop the controller houses the environmental sensors and status LEDs, ensuring accurate readings while minimizing heat interference. The LEDs provide helpful status updates, including warnings for excessive current draw or low battery charge, and they can be dimmed for dark sky conditions.

The Celestron Smart DewHeater and Power Controller 4X mounts easily on your CGE or CG-5 dovetail, or you can attach it to a tripod leg using the included strap for flexible setup options.

For optimal dew prevention, we highly recommend pairing the Smart DewHeater and Power Controller 4X with Celestron Dew Heater Rings, which are designed to fit seamlessly onto your Schmidt corrector lens. For further power efficiency, consider adding a dew shield to your setup—while not required, it helps reduce the amount of power the controller needs to provide to keep your optics dew-free.

Celestron's Smart DewHeater and Power Controller 4X is the ultimate solution for managing power and preventing dew, giving you a smarter, more efficient astrophotography experience.
