Customised medical power supplies deliver superior isolation
Luso Electronics announces availability of EFORE’s branded isolated MDP400 medical-grade ultra-efficient AC/DC power supplies. Certified to the latest IEC 60601 MOOP and 2 x MOPP safety standards for isolation and low leakage current, the power supply units are ideal for medical imaging, dialysis, ultrasound and laser and laboratory equipment, among other devices.
Power modules offer improved thermal resistance
Three series of three-phase-bridge power modules have been introduced by Vishay Intertechnology, designed to increase efficiency and reliability for heavy-duty industrial-level applications.
Battery research reaching out to higher voltages
For years, small rechargeable lithium-ion batteries have reliably supplied billions of portable devices with energy. But manufacturers of high-energy applications such as electric cars and power storage systems seek for new electrode materials and electrolytes. Michael Metzger, researcher at the Technical University of Munich (TUM), has now developed a new battery test cell allowing to investigate anionic and cationic reactions separately. Recent...
Isolator delivers 100mA via two adjustable power rails
Linear Technology introduces the LTM2887, a 6-channel SPI/Digital or I²C μModule isolator with dual rail regulated power that targets low voltage components, including newer DSPs and microprocessors. Two well-regulated adjustable supply rails (up to 5V) deliver more than 100mA of load current over the isolation barrier, with up to 62% efficiency. The voltages may be adjusted as low as 0.6V for the auxiliary supply, while the isolated logi...
Power connectors get current density boost
The current-carrying capabilities of Molex’s new Mega-fit power connectors have been extended to 23A per circuit. They are available in Europe at TTI. The power connectors provide far higher current density than existing mid-range power connectors and incorporate many features characteristic of Molex power products, including isolated terminals, polarised housings and positive housing locks.
Hybrid planar transformers offer lower cost
Vishay Intertechnology introduced a series of 250 W full-bridge hybrid planar transformers for avionics, industrial control, and alternative energy control applications. Featuring a unique winding structure, TPL-2516 series devices provide a cost-effective solution compared to traditional planar transformers while featuring smaller packages, improved performance, and easy customisation.
AC-DC adapters meet DoE, CoC standards
A robust portfolio of DoE Level VI and CoC Tier 2-compliant external AC-DC adapters is being offered to customers via a collaboration between CUI and Digi-Key Electronics. In February 10, 2014, the U.S. Department of Energy (DoE) published a revision to its EISA 2007 external power supply (EPS) efficiency standard, increasing the minimum efficiency requirements as well as expanding the range of products applicable under the new standard.
High performance MMIC products cover DC-26 GHz
Microsemi announced six new monolithic microwave integrated circuit (MMIC) products, including four wideband low noise MMIC amplifiers (MMA040AA , MMA041AA, MMA043AA and MMA044AA) and two wideband gallium arsenide (GaAs) MMIC switches (MMS006AA and MMS008AA). The new MMIC products are ideally suited for test and measurement, electronic warfare and radar applications.
AC/DC power supplies are medically fit
Dengrove Electronic Compoments is now offering the latest RACM range of AC/DC power supplies from RECOM. These latest PSUs are designed for medical applications, with certifications including CE marked and 3rd Edition UL/IEC/EN60601-1 medical certified with 2MOPP/ 250VAC.
