QHYCCD AC to 12V Power Adapter (US)
This AC to 12V Power Adapter is the official QHYCCD replacement for powering cooled cameras and other 12V accessories. QHYCCD cooled cameras require a stable input between 11V and 13.8V to operate correctly, making a reliable 12V source essential for consistent cooler performance and low-noise imaging.
Stable 12V Power for QHYCCD Cooled Cameras
This adapter provides the clean, regulated 12V DC power required by QHYCCD's thermoelectric cooling systems. It serves as a direct replacement for the power supply included with new QHYCCD cooled cameras, ensuring you have a reliable spare or can replace a lost or damaged unit without compromising your camera's operation.
Maintaining the 11V-13.8V Window: Why Cable Length Matters
A camera's cooling performance is directly tied to the stability of its power source. QHYCCD cameras specify an operational range of 11V to 13.8V delivered *at the camera*. Using excessively long or thin-gauge power cables can cause voltage drop, where the voltage arriving at the camera is lower than what the adapter supplies. For best results, always keep the power brick as close to the telescope and camera as practical.

Is this the same 12V power adapter that came with my QHYCCD camera?
Yes, this is the official AC to 12V Power Adapter from QHYCCD. It is identical to the one included in the box with their cooled cameras and serves as a direct replacement or a spare.
Why is a stable 12V power source important for my QHYCCD camera?
The thermoelectric cooler (TEC) in your camera requires a consistent voltage within the 11V to 13.8V range to maintain a stable sensor temperature. If the voltage drops too low, the cooler's efficiency decreases, which can lead to increased thermal noise in your images and an inability to reach your target cooling delta.
Can I use a long extension cord with this AC to 12V Power Adapter?
While you can use an AC extension cord to get power to your setup, you should avoid using long DC-side extension cables between the adapter's brick and the camera. A long DC cable is the primary cause of voltage drop, which can starve the camera of the power it needs, especially when the cooler is running at high power.
My QHYCCD camera's cooler isn't reaching its target temperature. Could this 12V adapter fix it?
If you are using a third-party power supply or a long DC extension cable, an unstable power source is a very likely cause of poor cooling. Switching to this official QHYCCD AC to 12V Power Adapter and ensuring a short cable run to the camera can often resolve issues with cooling performance by eliminating voltage drop.
Can I use this AC to 12V Power Adapter for other astronomy equipment?
Yes, this adapter can be used to power other 12V astronomy accessories, provided their power connector and amperage requirements are compatible. It is primarily intended for QHYCCD cameras but is a standard 12V DC source.
What plug type does this QHYCCD 12V power adapter use?
This specific model of the AC to 12V Power Adapter comes with a standard US-style two-prong mains plug for use in North American outlets.
