Murata Power Solution's MEJ2 series DC-DC converters offer strong energy efficiency while meeting electrical safety and medical standards.
Murata Power Solutions' MEJ2 series of encapsulated compact through-hole 2 Watt DC-DC Converters are designed to provide a pin-compatible upgrade path from Murata's NMJ, MEV1 and NMV series. The MEJ2 2W devices are available with either single or dual outputs covering the nominal voltages of 3.3, 5, 9, 12 or 15 V dc. Input voltage variants accommodate 3.3, 5, 12 or 15 V dc.
In a compact SIP format, the MEJ2 series offers safety agency recognition according to UL60950 for basic/supplementary insulation for voltages up to 200 Vrms. Recognition to the medical standard IEC 60601 (3rd Ed) is pending and provides for one measure of operator protection (MOOP) to 200 Vrms. The MEJ2 series can be used in high noise environments where conventional high isolation parts with 3 kV test ratings but only functional isolation (and no guaranteed spacings) may not be adequate.
The series maintains high levels of efficiency allowing the converter to save power, reduce temperature rise and increase product reliability.

Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
