Murata Power Solutions' Regulated Bus Converter (RBC) delivers
up to 210W output power, with a Vin range of 36-75V, efficiency of 92.5 percent
at full load with Vout regulation (±1.5 percent) in a quarter brick open frame
design of the RBC-12/17-D48 dc/dc bus converter has been optimized for use in
distributed power Regulated Intermediate Bus Architectures (RIBAs) where it can
be used to drive point-of-load (PoL) converters. Applications include
48V-powered datacom and telecom installations, base stations, cellular
telephone repeaters and embedded systems.
fully isolated (2250V dc) RBC-12/17-D48 is able to accept a wide range 36 to
75V dc (48V nominal) input. This is then converted to a 12V dc/17A output.
Overall dimensions of 2.22 (56.39) x 1.45 inch (36.83 mm) plus a low overall
height of 0.42 inch (10.67 mm) allow the RBC to fit into applications where
card cage space is restricted.
synchronous-rectifier topology and 225kHz fixed-frequency operation of the RBC
results in the efficiency levels. The present trend in distributed power architectures
(DPAs) require Wide Vin ranges, high efficiency and Vout regulation for the
most efficient regulated IBA systems.
features incorporated in this product are input under-voltage (UV) lockout,
output current limiting, short-circuit hiccup, over-temperature shutdown and
output over-voltage. Positive or negative polarity remote on/off control is
available as an option. A base plate, for mounting to cold surfaces or
natural-convection heatsinks, can be specified for applications that do not have
forced air cooling or where there is zero airflow. The RBC-12/17-D48 possesses
all relevant FCC, UL and IEC certifications for emissions, safety and
Independent science safety company Underwriters Laboratories is providing new guidance for manufacturers about how to follow the latest IEC standards for implementing safety features in programmable logic controllers.
Automakers are adding greater digital capabilities to their design and engineering activities to promote collaboration among staff and suppliers, input consumer feedback, shorten product development cycles, and meet evolving end-use needs.
