These Intermediate Bus Converter (IBC) modules are very efficient, low-profile, isolated, fixed-ratio converters for power system applications in enterprise and optical access networks. Rated at up to 850W, these IBCs conform to industry-standard eighth- and quarter-brick footprints. The greatly increased power capability often allows the eighth brick to replace a conventional quarter brick, while the quarter bricks can replace two or more conventional quarter bricks. Their leading efficiency enables full-power operation at 65°C with as little as 400LFM airflow. Their small cross section facilitates unimpeded airflow — above and below the thin body — to minimize the temperature rise of downstream components.
Input: 38 – 55VDC or 36 – 60VDC (75V transient operation for IB054 series)
Output: 9.6 or 12VDC at 48VIN
Output current: Up to 80A
98.2% peak efficiency
