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
package.
The
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.
The
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.
The
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.
Protection
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
flammability.
By experimenting with the photovoltaic reaction in solar cells, researchers at MIT have made a breakthrough in energy efficiency that significantly pushes the boundaries of current commercial cells on the market.
In a world that's going green, industrial operations have a problem: Their processes involve materials that are potentially toxic, flammable, corrosive, or reactive. If improperly managed, this can precipitate dangerous health and environmental consequences.
With LEDs dropping in price virtually every year, automakers have begun employing them, not only on luxury vehicles, but on entry-level models, as well.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
