DC power supply
DS460SDC-3 front end power supply by Emerson Network Power
The DS460SDC-3 is a compact 460-W bulk front-end power supply that can achieve a high typical conversion efficiency of 90% at 50% full load. It is ideal for systems that use distributed power architectures, especially in computing, storage, networking, and data communications, providing co-location centers with a very flexible means of addressing evolving power needs. The DS460SDC-3 is pin-for-pin compatible with Emerson Network Power’s ac-input DS460S-3 bulk power supply, enabling users to switch easily from an ac to a dc supply infrastructure. The DS460SDC-3 has a length of just 7.75 in., making it ideal for applications where rack depth is limited. The power supply also features active current sharing and supports N+1 redundancy operation. The DS460SDC-3 power supply has an operating temperature range of -10 to 50 C and features a built-in cooling fan with automatic speed control. The DS460SDC-3 has a high mean time between failures of 500,000 hours at full load and 50 C ambient operating temperature.
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.
