Bulk superconductor achieves magnetic field record
Dr Mark Ainslie of the Bulk Superconductivity Group, in conjunction with a Japanese research team, has achieved a bulk superconductor magnetic field record. The record-high trapped magnetic field of 1.1 T at 13 K in a magnesium diboride (MgB2) bulk superconductor using a practical, pulsed-field magnetisation technique comes on the heels of the Bulk Superconductivity Group's previous 2014 world record result, where 17.6 T was achieved in a st...
6W DC/DC converters feature medical safety approvals
Designed to be a cost-effective solution for applications in industrial and medical instrumentation requiring a certified compliance with the stringent industrial or medical safety standards, the ASA 6W-M series of 6W DC/DC converters has been introduced by Artesyn Embedded Technologies.
200W primary switched modules offer IP67 compliance
MTM Power has announced a series of primary switched modules, the PM-IP67A200 series, featuring IP67 ingress protection. The modules are especially designed for the electric supply of control, sensor and actuating systems in the field directly at the application. In order to achieve protection degree IP67 for conventional power supplies, it has been necessary to install them into switching cabinets or corresponding enclosures.
15dB gain block delivers 47dBm OIP3 linearity
Linear Technology announces the LTC6433-15, a wideband 15dB gain block amplifier offering outstanding linearity of 47dBm OIP3 (output third order intercept) and 3.22dB noise figure at 150MHz. The amplifier has excellent OP1dB (output 1dB compression point) of 19.2dBm. The LTC6433-15 is uniquely different from other gain block amplifiers that are typically built using GaAs or pHEMT processes.
A glimpse of the inner workings of thin transistors
A team of physicists at The University of Texas at Austin has had the first-ever glimpse into what happens inside an atomically thin semiconductor device. In doing so, they discovered that an essential function for computing may be possible within a space so small that it's effectively one-dimensional. In a paper published in the Proceedings of the National Academy of Sciences, the researchers describe seeing the detailed inner workings of a...
Project to produce and liquefy natural gas in northern Russia
The global vendor of power supply systems and provider of industrial power supply and renewable energy solutions, AEG Power Solutions, has announced that it was awarded a contract to supply equipment that will be insuring uninterrupted power supply for the Yamal LNG Project (Yamal-Nenets Autonomous Area, Russia).
Single-pole contact power relays suit switching currents of 10A
The power relays in Zettler's AZ940 series, now available at Schukat, have a single-pole contact and are designed for switching current of 10A. The electrical life expectancy of these high-performance PCB relays is 105 operating cycles, while the operating temperature range is between -40 and +85°C.
Fast ionic conductor for all-solid-state lithium battery
Rechargeable all-solid-state lithium batteries are expected to be one of the next-gen energy storage devices because of their high energy density, safety, and excellent cycle stability. The materials used for the solid electrolyte must not only have a high lithium-ion conductivity above 1 mS/cm at room temperature, but also possess chemical stability. Oxide-based solid electrolyte materials have several advantages over sulfide-based ones, such as...
Consistent results with portable power supplies
Power quality specialist REO UK has refreshed its REOLINE range of portable power supplies for laboratory, test and factory applications. The range provides an adjustable low-loss output voltage, integrated short-circuit protection and does not generate ElectroMagnetic Interference (EMI), ensuring that the power supply is consistent and reliable.
External power supplies meet DOE level VI energy efficiency standards
A division of SL Industries, SL Power Electronics has announced the expansion of its highly efficient Level VI+ family with the addition of its TE90 series external power supplies.
