Work smarter, not harder, when it comes to combating dew. The Smart DewHeater and Power Controller 4X prolong your battery life by optimizing power usage for up to four dew heaters. The controller gathers and analyzes information in real-time to warm your optics just enough to prevent dew.
The Smart DewHeater and Controller comes with four ports to control four dew heaters at once. You can use one port to heat your optical tube while the others warm a second optical tube, a guide scope, an eyepiece, or another accessory. The controller is also a complete power management solution for your telescope. It offers four 12V DC output ports to power a variety of 12V DC devices, such as your mount, focuses motor, and camera. One of the ports has variable voltage, which you can adjust from 3V to 12V. In addition, the controller features three powered USB ports.
The Smart DewHeater and Controller work seamlessly with Celestron’s Dew Heater Rings, which have a built-in thermistor to provide temperature readings of the corrector lens. Third-party dew heater bands or straps are also compatible; you simply need to add Celestron's Thermistor for Smart DewHeater and Controllers (sold separately).
