ELECTRONICS: Only months after the launch of the new 4-W Class, RECOM introduces the RAC20-SB, a highly efficient solution in the medium power range of up to 20-W.This ultra-compact converter measures only 52.4 x 27.2 x 23.5 mm (LxWxH), and is supplied in the same housing as the popular 10-W model and is also pin-compatible with the equally popular 5-W model.
The converters are designed for use on universal mains with input voltages of 90 to 264V ac and are available with output voltages of 3.3, 5.0, 12, 15 and 24V. All the models attain an unusually low no load consumption of under 500 mW. These not only meet the EU’s “green power” policies for 2010, but also those planned for 2013.
Compared to its predecessor, the power density of the module has been increased by 120 percent to 0.6 W/cm3. Efficiency varies according to output voltage limits, reaching a peak of 86 percent at 24V. In free air convection, the ambient temperature operating range of the converters is between -40 to 70C. The RAC20-SB family is also fitted with an integrated “Class B” filter. All models are isolated to 3000V dc minimum and exhibit a MTBF of 250,000 hours to MIL-HDBK-217F specifications.
Gigabit and PoE are two networking technologies moving ahead in tandem as industrial users power remote Ethernet devices such as IP security cameras at 1,000 Mbps over existing CAT5 cable.
New disc magnet motors fit into the design trend of stepping up to closed loop performance while maintaining the cost advantage of stepper motor technology.
At the Design News webinar on June 27, learn all about aluminum extrusion: designing the right shape so it costs the least, is simplest to manufacture, and best fits the application's structural requirements.
A new battery design, which replaces lithium with abundant and low-cost elemental sulfur, is still in its nascent stages but shows real promise for giving batteries more energy potential.

For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
