In a quarter brick open frame package measuring 56.39 mm x 36.83 mm x 10.67 mm, the Regulated Bus Converter (RBC) series dc/dc converter delivers up to 210W of output power with a Vin range of 36 to 75 Vdc and maintains an efficiency of 92.5% at full load with ±1.5% Vout regulation. Optimized for use in distributed power regulated intermediate bus architectures (RIBAs), applications include 48V-powered datacom and telecom installations, base stations, cellular telephone repeaters, and embedded systems. Protection features include input under-voltage lockout, output current limiting, short-circuit hiccup, over-temperature shutdown, and output over-voltage. Positive or negative polarity remote on/off control is optionally available. MURATA POWER SOLUTIONS INC., Mansfield, MA. (508) 339-3000.
