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
In a year when manufacturing continued to lead the economic rebound, it makes sense that plant manager bonuses rebounded. Plant Engineering’s annual Salary Survey shows both wages and bonuses rose in 2012 after a retreat the year before.
Average salary across all job titles for plant floor management rose 3.5% to $95,446, and bonus compensation jumped to $15,162, a 4.2% increase from the 2010 level and double the 2011 total, which showed a sharp drop in bonus.
