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.\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\u003e19.2W-21.6W of Consistent Heat to Defeat Dew\u003c\/h3\u003e\n\u003cp\u003eOperating 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.\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\u003eDurable Multi-Layer Construction with 1m Power Cord\u003c\/h3\u003e\n\u003cp\u003eThe 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.
