SVBONY SV192 12V Dew Heater Strip 560mm
- Delivers 19.2W to 21.6W of heating power
- Standard 12V DC operation with 5.5x2.1mm plug
- Draws a consistent 1.7A (±0.1A) current
- Flexible 1m TPE Silica power cord for cold weather
- Adjustable temperature
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.
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. The strip's temperature is adjustable to suit changing humidity and temperature.
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.
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.
Yes, the heating output is adjustable.
No. An 8" Schmidt-Cassegrain tube has a circumference of roughly 720mm, longer than the 560mm strip, so it cannot wrap around the corrector cell. Choose a longer strip for an 8" SCT.
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.
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.
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.
