ELECTRONICS:Wieland’s new family of UL Listed and CSA Certified (cULus), switching power supplies delivers a control voltage of 24V dc, at an output current from 1.25A to 40A. Wieland offers nine models including six single-phase and three three-phase, approved worldwide for a temperature range from -25 to 71C. All models feature short circuit protection and a robust, proven design.The six fully enclosed, single-phase units take minimum space on the DIN rail as their width varies from only 1.7 inch (43.5 mm) to 6.9 inch (175 mm). All single-phase models accept a wide universal input voltage range, allowing one unit to operate in many applications. Input voltage for three units range from 115/230V ac and 210 - 375V dc, for two units from 85 - 264V ac and 90 - 375V dc, and for one unit from 115/230V ac and 120 - 370V dc. Output current varies from 1.25 to 20A dc.
The three fully enclosed, three-phase units measure only 3.5 inch (90 mm) to 10.9 inch (276 mm) wide. All three-phase models accept a wide universal input range, 400 - 500V ac and 480 - 820V dc. Output current varies from 10A to 40A dc. Single-phase and three-phase units feature touch-proof screw terminations for input and output wire connections to ensure personnel safety.
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
