Gresham stocks EOS’ smallest 120W PSU
EOS has introduced a 120W open-frame PSU measuring 50 x 75 x 30mm, its smallest yet at 16.94W/in3. The input is universal: 85-264Vac 47-63Hz, and there is a choice of single outputs: 12, 15, 24, 30, 48, or 58Vdc. Available in medical and commercial versions, it can deliver 100W with convection cooling as well as 120W with ...
Mitsubishi claims IGBT power record at 6.5kV
The highest capacity and highest operating temperature in the industry, is what Mitsubishi claimed at the launch of its 6,500V, 1,000A, 150C X-Series IGBT module. Called CM1000HG-130XA, power losses are ~20% down compared with its existing IGBT module (CM750HG-130R) through the use of seventh-generation ‘CSTBT’ chip and ‘RFC’ diode chips, said the firm. Applications are ...
LED Engin claims flux record for RGBW lighting LEDs
Led Engin is claiming a flux density record with a combination of red, green, blue and white die that deliver 3,800 lm from 25 die in a 6.2 x 6.2 mm square on a 12 x 12mm substrate. Power input is 80W, leading to the claim of a “new world record in both flux and ...
Plessey gets business from Circadian lighting
Plessey is to develop packaged LEDs for circadian-modulated LED lighting systems from Massachusetts firm Circadian ZircLight. Developments at Circadian, according to Plessey, build upon a growing body of research showing that exposure to light at night causes a disruption of brain neuroendocrine systems, including melatonin and cortisol rhythms. “We are developing a set of human-centric ...
Toshiba reported to be planning semiconductor re-structuring
This week Toshiba is expected to decide on a plan to re-structure its semiconductor business, reports the Japanese press. The first step has already been taken – a $165 million disposal of its sensor business to Sony. However it is reported that more steps will be taken which may involve ‘thousands’ of job losses. Toshiba’s ...
AYLA Networks finds gold in Clouds
Five year-old Ayla Networks, which runs machine-to-Cloud-to-mobile device networks, has gone from 25 to 100 people in the last 15 months. “The market is growing so fast,” says CEO and co-founder David Friedman. Asked what kind of people he’s recruting he replies: “Cloud engineers – people who understand enterprise systems running on big data centres ...
High speed CAN FD bus is coming to cars, says Microchip
Microchip is working with CANbus specialist Kvaser to integrate the Swedish firm’s CAN and CAN Flexible Data-Rate (CAN FD) IP in its microcontrollers. CAN FD is a higher data rate extension to the original CAN protocol as specified in ISO 11898-1, which is used for in-car networks. It allows for a higher data rate and larger packet ...
50 and 75W quarter brick for railways
Minmax is aiming at railway applications with two convection-cooled quarter brick dc-dc converters with EN550155 / IEC60571 railway approvals and EN50121-3-2 railway EMC compliance. MTQZ50 (50W) and MTQZ75 (75W) each come in two basic variants, for 72Vdc (43-101V) and 110Vdc (66-160V) input ranges. Each input range variant then offers four types, with 5, 12, 15, or 24 ...

Are these the rising stars of solar?
Perovskite solar cells seem to be the promising new kid on the block and this fast-improving technology is already demonstrating silicon-like efficiency, without resorting to mono-crystalline semiconductor processing. According to researchers at Imperial College, London, the efficiency of perovskite cells has risen rapidly from less than four per cent in 2009 to over 20 per cent ...
