  • SVBONY SV192 Dew Heater Strip 12V for Telescopes and Lens

    The SVBONY SV192 Dew Heater Strip delivers 19.2W to 21.6W of adjustable heat to keep your optics free of condensation throughout the night. It draws a consistent 1.7A (±0.1A) from any standard 12V field power supply using a common 5.5x2.1mm interface. The integrated 1m TPE Silica power cord provides ample reach and remains flexible even in freezing temperatures, ensuring reliable power delivery when you need it most.

    19.2W-21.6W of Consistent Heat to Defeat Dew

    Operating within a 19.2W to 21.6W power range, the SV192 provides enough thermal energy to gently raise your lens or corrector plate temperature just above the dew point without introducing tube currents. Powered by a standard 12V source and drawing 1.7A, it's fully compatible with the power tanks and batteries used in most field astrophotography setups. While the strip's temperature is adjustable, this requires an external dew controller to fine-tune the power output for changing humidity and temperature.

    Durable Multi-Layer Construction with 1m Power Cord

    The SV192 is built from a composite of imitated OK cloth, SBR, Black-T fabric, aluminum film, and cotton, a combination that ensures both durability and efficient, even heat transfer to your optics. The 1m power cord is made from TPE Silica, a material chosen for its ability to resist kinking and cracking in cold weather. It terminates in a standard 5.5x2.1mm DC plug, making it a simple, plug-and-play solution for most astronomy power systems.

  • What kind of power supply do I need for the SVBONY SV192 Dew Heater Strip?

    You need a 12V DC power source capable of providing at least 1.7A (±0.1A) of current. The strip connects via a standard 5.5x2.1mm plug, which is common on most astronomical power tanks and portable batteries.

    Is the temperature of the SVBONY SV192 Dew Heater Strip adjustable?

    Yes, the heating output is adjustable. However, the SVBONY SV192 strip itself does not have a built-in controller. You must connect it to an external dew heater controller, which allows you to vary the voltage and precisely manage the power output based on ambient conditions.

    How can I prevent my 8" SCT corrector plate from dewing up with the SVBONY SV192?

    For an 8" Schmidt-Cassegrain Telescope, you should wrap the SVBONY SV192 strip around the metal cell of the optical tube, just behind the corrector plate. This positioning gently warms the glass from the edge, preventing dew from forming on the optical surface without degrading the image.

    Will the SVBONY SV192 work on my camera lens for nightscape photography of the Milky Way?

    Absolutely. The SVBONY SV192 is ideal for preventing dew on DSLR or mirrorless camera lenses during long exposures. Simply wrap the strip around the lens barrel, as close to the front element as possible without interfering with the focus or zoom rings, to keep the glass clear all night.

    What is the power cord on the SVBONY SV192 designed for?

    The SVBONY SV192 features a 1m power cord made of TPE Silica. This material is specifically chosen for its excellent flexibility in cold weather, preventing the cord from becoming stiff or brittle during winter observing sessions.

    What materials are used in the SVBONY SV192 strip?

    The strip is constructed from a multi-layer composite designed for durability and efficient heating. The materials include imitated OK cloth, SBR, Black-T fabric, aluminum film, and a cotton layer.
