EC: EZ Programmable Power Supply
Power - Energy, power protection: The EZ Programmable Power supply is an industrial 24 V dc, single phase, NEC Class 2, din-rail switched mode power supply with unique displays for voltage/current readouts and maintenance alarms. This is a Control Engineering 2013 Engineers' Choice finalist.
With EZAutomation's Programmable Power Supply, EZPPS, plant maintenance no longer need to bring a volt meter to the control cabinet when a device is not powering up. Furthermore, before an HMI, PLC, ac drive or any other control equipment dies due to no power input, thus causing a manufacturing line to stop, a warning signal can be sent to maintenance to avoid any down time!
EZAutomation's, EZPPS, are field programmable power supplies that include built-in digital displays that provide, at a glance, additional information without connecting a multi-meter. The NEC Class 2 models add flexibility through easy, field-programmable current-limit using the displays and two buttons. The power supplies, in 30 W, 60 W, and 90 W models, have a 3-digit LED display for output voltage and 2-digit LED display for output current.
The power supplies also have maintenance timer functions, showing expected lifespan based on usage, a function that is particularly valuable to schedule replacement before an outage occurs. (Electrolytic capacitors in a switching power supply have limited life, depending upon current and temperature.) A pre-failure warning alarm can go to a stack light or other device accepting the output signal.
Other attributes include DIN mount compact plastic housing at 3.1 in. x 1.8 in. x 4 in. deep, and plug-in connectors for easy maintenance. Operating temperature is -25 to 60 C, with 95% relative humidity. The units have 24 V dc output with less than 100 mV peak to peak ripple, with 1% load regulation; output voltage adjustable from front plate, +5%, to -10%; and 85-264 V ac universal input voltage.
In addition, the unit is protected against an output short or an overload with automatic recovery. In summary, EZAutomation's, EZPPS brings a new, simple and intuitive approach to power supplies that can minimize troubleshooting and downtime, while remaining both cost-competitive and made in America.

2012 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.
