Its integrated 1m power cord is made from flexible TPE Silica, and the multi-layer strip construction ensures efficient thermal transfer to keep your optics clear throughout the night.\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\u003e12V Power for 19.2W-21.6W of Dew Prevention\u003c\/h3\u003e\n\u003cp\u003eEngineered for field use, the SV192 operates on a standard 12V DC input, making it compatible with virtually all field batteries and astronomy power supplies. It draws a steady 1.7A to produce between 19.2W and 21.6W of thermal power, enough to combat moderate to heavy dew without excessive battery drain. The ability to adjust the temperature allows you to apply just enough heat to stay above the dew point, conserving power for longer imaging sessions.\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\u003eAll-Weather Construction for Field Reliability\u003c\/h3\u003e\n\u003cp\u003eThe SV192 strip is built from a composite of imitated OK cloth, SBR, Black-T fabric, aluminum film, and cotton. This multi-layer design provides durability against moisture and abrasion while the internal aluminum film ensures heat is directed inward toward your optics, not lost to the night air. The 1m power cord is sheathed in TPE Silica, a material that remains flexible even in cold temperatures, preventing cracks and connection failures during critical moments.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhat kind of power supply do I need for the SVBONY SV192 Dew Heater Strip?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eYou will need a \u003cstrong\u003e12V DC power source\u003c\/strong\u003e with a female \u003cstrong\u003e5.5x2.1mm\u003c\/strong\u003e connector.
