Page 101 DC-DC Converter Modules from Murata


Mansfield, MA — Murata has introduced the SPM series of low power isolated DC-DC modules designed specifically for use in electronic equip- ment that will be subject to harsh environments such as outdoor communications, applications with little or no forced air cooling, smart grid and indus- trial process control equipment. The SPM15 series modules are designed for applications that require Vin ranges of 9-36V or 18-75V at 15W. The SPM25 series covers applications that require Vin of 36- 75V at 25W. These compact, 5-sided shielded, encapsulat-


ed converters, measuring 25.4 x 25.4 x 10.41mm offer an industry standard footprint, incorporate the latest PWM technologies, automated assembly processes and synchronous rectification tech- niques to achieve one of the industry’s highest energy efficiency ratings of 88 percent. A thermally conductive encapsulation materi-


al greatly improves the thermal per- formance in applications where there is little or no airflow, provid- ing a stable platform for environ- ments where dirt and dust, vibra- tion or extreme temperature varia- tions are likely to occur during nor- mal operation. The SPM15 and SPM25 mod- ules provide single output voltages


New Graphics Display from Electronic


Assembly Gilching, Germany — The EA DOGM240-6 is a new graphics dis- play from Electronic Assembly. It is available immediately as a complete package that uses high-contrast supertwist technology (STN and FSTN). In addition, a backlight can be supplied, and a touch panel and a USB test board can be ordered as optional accessories. The display comes with the UC1611s controller and a built-in graphics RAM. There are 3 different LED back-


lights to choose from (white, amber and a two-color red/green). The dis- play can be ordered with white, black, blue or super white, reflective background. It runs on a standard 2.7 to 3.3V supply at temperatures between –20 and +70°C. Current consumption is typically


500µA. 3-wire and 4-wire SPI and I2C bus serial ports are available. The long, compact display (94 x 40mm external dimensions) is suit- able for installation on 19-in. sys- tems with 1 RU or more. A simulator which runs under


Windows is available as a download on the website. It can be used to sim- ulate all of the displays and colors without any hardware, making it very easy to view user-defined images and text that will appear on the display. When the EA 9780-3USB test


board is connected to the PC USB port, users can get an immediate impression of the display’s contrast, viewing angle and brightness. Absolutely no software skills are needed and the display is automati-


cally powered from the UBS port. Contact: Electronic Assembly GmbH, Zeppelinstr. 19, 82205

Capacitors for Power Electronics


of 3.3, 5 or 12VDC. In addition, the SPM15 has a 15VDC output option. The SPM15 is available with two wide input range options of 9 to 36VDC or 18 to 75VDC. The SPM25 accommodates an input range around a 48VDC nominal from 36 to 75VDC. The operating temperature range is from –40 to +85°C, and the modules are designed for use in the most demanding environments. Protection features include over-current, over-temperature and under-voltage lockout. Basic insulation provides input-to-output isolation of 1,600VDC. The modules are suitable for use in high-reli- ability industrial process control, smart grid and


transportation infrastructure equipment. Contact: Murata Power Solutions, Inc., 11
