IBC Module IB0xE120T32xx-xx S CUNRTL S C US 4:1 Intermediate Bus Converter Module: Up to 300W Output Features & Benefits Input: 36 60V Low profile: 0.38 height above DC (38 55V for IB048x) board DC Output: 12.0V at 48V Industry standard 1/8 Brick pinout DC IN Output current up to 32A Sine Amplitude Converter (SAC) Size: Output power: up to 300W * Low noise 1MHz ZVS/ZCS 2.30 x 0.9 x 0.38in 58.4 x 22.9 x 9.5mm 2250V isolation DC (1500V isolation for IB048x) DC 97.9% peak efficiency Typical Applications * For higher power applications, see 500W model IB0xxE120T40xx-xx Enterprise networks Optical access networks Product Description Storage networks The Intermediate Bus Converter (IBC) Module is a very efficient, low prolfi e, Automated test equipment isolated, fixed ratio converter for power system applications in enterprise and optical access networks. Rated at up to 300W from 36 to 60V , the IBC conforms to an industry IN standard eighth-brick footprint. Its leading efficiency enables full load operation at 55C with only 200LFM airflow. Its small cross section facilitates unimpeded airflow above and below its thin body to minimize the temperature rise of downstream components.
