It delivers the stable 12V supply required by QHYCCD cooled cameras, which have a strict operational tolerance between 11V and 13.8V.\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\u003eStable 12V Power for QHYCCD Cooled Cameras\u003c\/h3\u003e\n\u003cp\u003eA cooled astronomy camera's performance is directly tied to its power source. The thermoelectric cooler (TEC) requires a constant, stable voltage to maintain a precise sensor temperature for accurate dark frame calibration. This adapter is specified to deliver a reliable 12V output, preventing inconsistent cooling that can introduce thermal noise into your images.\u003c\/p\u003e\n\u003cp\u003eTo avoid voltage drop, which can starve the camera of power and cause performance issues, it is critical to keep the power supply close to your setup. Long or thin-gauge DC extension cables can cause the voltage to fall below the camera's required 11V minimum, especially under the full load of a TEC running at maximum power.\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\"\u003eWhy do I need this specific 12V adapter for my QHYCCD camera?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eQHYCCD cooled cameras require a stable voltage between \u003cstrong\u003e11V and 13.8V\u003c\/strong\u003e to operate their thermoelectric coolers correctly. This official adapter is designed to provide a reliable 12V source, ensuring consistent cooling and preventing thermal noise from compromising your images.

While this adapter supplies a stable 12V, using a long or thin DC extension cable can cause significant voltage drop. If the voltage at the camera inlet falls below 11V, the cooler will be underpowered. Ensure the adapter is close to the camera and you are using a high-quality, appropriately short power cable.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eIs this AC to 12V Power Adapter the same one that came with my camera?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eYes, this is the official QHYCCD-supplied power adapter with a UK mains plug.

This leads to inconsistent sensor temperatures during an imaging session, which invalidates dark frame calibration and can result in images with higher-than-expected thermal noise and other artifacts.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eCan I use this 12V adapter to power other astronomy gear, like my GoTo mount?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eWhile the adapter provides a 12V output, it is primarily specified for QHYCCD cameras. Before using it with other equipment, such as a mount or focuser, you must verify that the device's power requirements (amperage, polarity, and connector type) are compatible. Using an incorrectly matched power supply can damage your equipment.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eHow can I minimize voltage drop when using the AC to 12V Power Adapter?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe best practice is to place the AC adapter as close to your telescope and camera as possible. Use the shortest, thickest-gauge DC power cable that your setup allows to connect the adapter to the camera. This minimizes electrical resistance and ensures the camera receives the full, stable voltage it needs.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ctable class=\"DAV-specifications\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eAC to DC Power Adapter\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Voltage\u003c\/td\u003e\n\u003ctd\u003e12V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Plug\u003c\/td\u003e\n\u003ctd\u003eUK Mains Plug\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePrimary Compatibility\u003c\/td\u003e\n\u003ctd\u003eQHYCCD Cooled Cameras and 12V Accessories\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cul class=\"DAV-grid\"\u003e\n\u003cli class=\"DAV-grid-item\"\u003e\n\u003cdiv\u003e\n\u003cp class=\"DAV-item-title\"\u003eAC to 12V Power Adapter (UK)\u003c\/p\u003e\n\u003cp class=\"DAV-item-subtitle\"\u003e× 1\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp\u003eThis product does not require specific drivers or software.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/davidastro.com\/pages\/qhyccd-warranty-policy\" rel=\"noopener\" target=\"_blank\"\u003eQHYCCD Warranty\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"QHYCCD","offers":[{"title":"Default Title","offer_id":52942994931997,"sku":"QHY-050006","price":49.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0753\/5280\/1565\/files\/QHYCCD-AC-to-12V-Power-Adapter-UK-1_5808b3cc-b6c3-4fab-a14a-a35dfd121fad.jpg?v=1789615139","url":"https:\/\/davidastro.com\/fr\/products\/qhyccd-ac-to-12v-power-adapter-uk","provider":"David Astro","version":"1.0","type":"link"}
