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.

Annual Salary Survey
Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.
There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.
But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
