While Switch mode Power Supplies are excellent choice for powering Telescopes, Focusers or Heaters, being small cheep and efficient, they are totally unsuitable for powering CCD cameras. Outputs of such Power supplies contain high frequency AC component that will show as increased noise on your CCD image. Even most basic linear Power Supply (Bridge rectifier, filter capacitor, voltage regulator, output capacitor) will do better job powering CCD camera then most expensive “switcher”.<o:p></o:p>
So, if your expensive CCD imaginer is outputting noisy image, have look on your Power supply first. <o:p></o:p>
