Korea Astronomy Observatory (KAO) recently developed a new model of CCD imaging system for astronomical purpose. This paper presents system structure and electrical circuit descriptions with the performance of the CCD imaging system. The developed system can handle astronomical image acquisition with additional functions of on-chip binning, sub-image acquisition using a SITe 1024×1024 1024×1024 CCD chip. Particularly the controller design of the system allows us great flexibility and versatility with the software system control and it is possible to cope with any format CCDs by any manufactures, in principle. The system performances are derived by mean variance test in our laboratory, which shows that the total system noise 10.5e-(R.M.S), Gain 1.9e-/ ADD, non-linearity 0.37% 0.37%
