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.
Two researchers from Cornell University have won a $100,000 grant from NASA to continue work to develop an energy-harvesting robotic eel the space agency aims to use to explore oceans on one of the moons of Jupiter.
Is the factory smarter than it used to be? From recent buzzwords, you’d think we’ve entered a new dimension in industrial plants, where robots run all physical functions wirelessly and humans do little more than program ever more capable robotics. Some of that is actually true, but it’s been true for a while.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
