4X\u003c\/h2\u003e\n\u003cp\u003eThe Celestron Smart DewHeater and Power Controller 4X is a complete power and dew management solution, providing intelligent control for four dew heaters and distributing power to your entire imaging rig through 10 separate outputs. With two 12V DC inputs, including a high-current XT60 jack rated for a 20A maximum input, this controller can power a mount, camera, and accessories from a single source. An integrated environmental sensor feeds data to a microprocessor, which optimizes power usage in real time to keep your optics clear while conserving battery life, all housed in a 1.4 lbs aluminum enclosure.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003e4-Channel Intelligent Dew Prevention\u003c\/h3\u003e\n\u003cp\u003eThis controller eliminates guesswork by using data to apply heat precisely where and when it's needed. It features four RCA-jack dew heater ports, each paired with a 2.5mm thermistor port, allowing it to constantly monitor the temperature of your optics. The unit's integrated environmental sensor measures ambient temperature and humidity, letting the processor calculate the exact dew point and deliver just enough power to prevent condensation, significantly extending your field battery life.\u003c\/p\u003e\n\u003cp\u003eWhile the controller is designed to work seamlessly with Celestron's Dew Heater Rings (which have built-in thermistors), it is also fully compatible with third-party heating straps.

Many DSLR or mirrorless cameras, for example, use batteries around 7.4V. This port allows you to power such devices directly with the correct voltage, eliminating the need for separate power adapters or batteries.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eHow do I connect the Smart DewHeater and Power Controller 4X for software control?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eYou have two main options. You can connect the Controller 4X to your Celestron mount's hand control using one of the \u003cstrong\u003ethree AUX ports\u003c\/strong\u003e and the included AUX cable. Alternatively, for full computer control with CPWI software, you connect the controller directly to your PC using the \u003cstrong\u003eUSB 3.2 Type B port\u003c\/strong\u003e.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eI have a full imaging setup.

In heavy dew, running multiple dew heaters at high power, plus a mount, camera, and other accessories, will likely exceed the capacity of a single 17Ah battery for an all-night session. For demanding setups, a larger capacity battery source or multiple batteries is recommended to ensure you don't lose power before sunrise.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhat is the difference between the XT60 and barrel connector power inputs on the Controller 4X?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe controller provides two options to match your power source.
