Celestron Smart DewHeater & Power Controller 4x

Celestron Smart DewHeater and Power Controller 4X – Intelligent Dew Control & Power Management in One

Combat dew efficiently and power your entire astronomy setup with the Celestron Smart DewHeater and Power Controller 4X—a powerful all-in-one solution for dew prevention, environmental monitoring, and accessory power management. Whether you’re observing or imaging under humid skies, this advanced controller ensures your optics stay clear and your gear stays powered, all night long.

Designed for serious astrophotographers and deep-sky observers, this intelligent device monitors conditions in real-time and optimises performance automatically—so you can focus on the sky, not your equipment.

Intelligent Dew Control – Automatic & Efficient

No more guesswork, wasted power, or fogged optics. The Smart DewHeater and Power Controller 4X uses a built-in microprocessor to:

• Continuously analyse environmental conditions and heater temperatures

• Deliver just the right amount of warmth to prevent dew formation

• Preserve your battery by avoiding unnecessary heat output

With four heater ports, you can control multiple dew heaters at once—ideal for warming your:

• Primary optical tube

• Guide scope

• Eyepieces

• Accessories

Universal Compatibility with Celestron & Third-Party Accessories

The controller works seamlessly with Celestron Dew Heater Rings, which feature a built-in thermistor for precise temperature feedback. For third-party heater bands, simply add the Celestron Thermistor (sold separately) for full compatibility and smart control.

Full Power Hub for Your Astronomy Setup

The Smart DewHeater and Power Controller 4X isn’t just a dew heater controller—it’s a centralised power hub for your entire rig:

• Four 12V DC output ports to power mounts, cameras, focus motors, and other devices

• One adjustable voltage port (3V to 12V) ideal for accessories like DSLR cameras

• Individually control each port’s power via Celestron CPWI software or a compatible hand control

Built-in electronic resettable fuses protect your gear in case of power surges or excessive current draw.

Power Tip: If you’re running multiple dew heaters and powering several devices under heavy dew conditions, a single PowerTank Lithium Pro or PowerTank 17Ah may not last all night. We recommend using a high-capacity battery or multiple batteries to support extended sessions.

Built-In USB 3.2 Hub – Simplify Your Cable Management

Streamline your imaging setup with the integrated powered USB 3.2 hub:

• Connect up to three USB Type-A devices (e.g., camera, focuser, guide camera)

• All ports are individually powered and controllable via CPWI or hand control

• One single USB cable connects everything to your PC, reducing clutter

Perfect for remote setups, portable observatories, or complex astrophotography rigs.

Rugged Design, Smart Features

Crafted for field durability and intelligent performance, the Smart DewHeater and Power Controller 4X features:

• A robust metal housing with integrated cooling fan

• Status LEDs to alert you of power issues, overcurrent, or battery status

• Dimmable lighting to preserve your night vision

• The Bridge: A raised, sensor-equipped section with built-in temperature and humidity sensors, positioned away from heat sources for accurate readings—no external sensor cables required

Flexible Mounting Options

The controller includes integrated dovetail clamps for direct mounting on Celestron CGE or CG-5 dovetails. Prefer tripod mounting? Use the included leg strap for a secure, alternate setup.
