AC-DC power supply achieves 92 percent efficiency at 50 percent full load Murata has introduced the Murata Power Solutions D1U86G series of 86 mm wide, 460 Watt front end power supplies which can achieve a high minimum conversion efficiency of 92 percent at 50 percent full load. With 1U form factor, the units measure 86.0 x 196.9 x 39.9 mm, ideal for length-limited applications and mid-plane design architectures. The unit’s high efficiency lowers the host system cooling requirements and also contributes to power savings in customer applications. The D1U86G series comprises two models, both providing a + 12 VDC 460 Watt output with either ‘back to front’ or ‘front to back’ direction of airflow . The power factor corrected D1U86G series accommodates the universal AC input range from 90 to 264 VAC. Forced air cooling is provided by an internal variable speed fan. The series features a 0 to 50 degrees C operating temperature range, without any derating due to line input or temperature. The D1U86G series features hot-swapping and hot plug capability and droop current sharing for up to 8 supplies to be connected together. Safety features include output overvoltage, output overcurrent, and self-resetting overtemperature protection. PMBus management and I2C interface with status indicators and boot loading are also available. An LED on the front panel indicates the operational status of the power supply. Murata Europe www.murata.eu High-power projectors provide a system output of up to 1700 lumen Osram Opto Semiconductors has launched two high-power versions of the Osram Ostar Projection for projectors with a brightness of up to 1700 lumen. Thanks to their optimized product design they offer high luminous flux from the available chip surface. Between 1000 and 8300 lumen can be produced depending on the color and the LED version. An antireflex coated glass cover instead of the usual lens, together with external optics, ensures that the light is very well bundled. The two new light emitting diodes offer so much luminous flux that they can be used in office projectors with brightness levels of up to 1700 lumen. At the heart of the product is a 2 mm² LED high-current chip based on state-of-the-art thin-film and UX:3 technologies. The two LED versions contain two (P1W) or four chips (P2W) with a total luminous area of 4 mm² and 8 mm² respectively. In LED projectors three LEDs in the colors red, green and blue serve as the light source. The LEDs are pulsed one after the other (color sequential mode), making the color filter wheel used in classic lamp projectors superfluous. The high output of the new LEDs comes from the latest chip technologies and Osram C² conversion technology for a particularly efficient green. The P2W version emits light pulses with brightnesses of 1000, 2500 and 8300 lumen for Blue, Red and Green. These high brightness levels require current pulses of up to 32 amps (8 amps per chip) and optimized product design to efficiently remove the resulting heat.. Osram Opto Semiconductors Small form factor rugged CP based on 4th www.osram-os.com generation Haswell Core processor ADL Embedded Solutions is to start shipping its latest small form factor PC for rugged environments in January. The ADLQM87PC PCIe/104 SBC is based on the 4th generation LED family handles drive currents to 70mA The Optoelectronics group of Vishay Intertechnology, Inc. has released a family of LEDs in a PLCC-2 package that can handle higher drive currents and produce improved luminous intensity. The new VLM.334.. series LEDs, an advanced modification of Vishay’s VLM.31.. series LEDs, can incorporate larger chips and are thus capable of withstanding drive currents up to 70 mA. The AEC-Q101-qualified VLM.334.. LEDs are offered in super red, red, amber, and yellow to serve a wide range of applications, including traffic signals and signs, interior and exterior lighting, automotive dashboard illumination, indicators and controls for audio and video equipment, LCD switches and symbols, illuminated advertising, and many other uses. Utilizing the latest advanced AllnGaP technology, the VLM.334.. series devices claim to provide exceptional brightness with a typical luminous intensity of 3760 mcd and maximum luminous intensity of 6052 at 70 mA while delivering improved thermal performance compared to previous-generation LEDs. At 300 K/W, junction-to-ambient thermal resistance is 25% lower than the former VLM.333 product. VLM.334.. series LEDs are available in 8 mm tape. RoHS-compliant, halogen-free, and Vishay Green, the devices are compatible with IR-reflow soldering processes and preconditioned according to JEDEC Level 2a. Vishay Intertechnology www.vishay.com Haswell Core processor, built on Intel’s 22nm tri-gate process technology. This will enable ADL Embedded Solutions to continue its focus on small form-factor embedded computing after the release last year of a PCIe/104 second generation Intel Core i7 ADLQM67PC platform. The ADLQM87PC builds on the ADLQM67PC to include new features like USB 3.0, TPM v1.2, and an onboard minicard socket for miniPCIe and mSATA modules. This will enable all manner of applications including WiFi and onboard bootable mSATA flash modules. Additional features include support for next generation digital video interfaces including Display Port, DVI-D, HDMI, and embedded-DP, as well as a full-complement of I/O including SATA 6Gb/s, 2xGLAN, 8xUSB2.0, 2xUSB3.0, and a downstacking Type 1 PCIe/104 bus for peripherals.
