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
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
