Field programmable power supplies have readouts, maintenance alarm
Product Exclusive: New AC Autotech Smart Power field programmable 30 W, 60 W, and 90 W power supplies from AVG Automation include built-in displays for current and voltage readout and pushbuttons for setting current limit. They can show operating life left, based on usage. See a video demonstration.
AC Autotech Smart Power field programmable power supplies from AVG Automation include built-in digital displays that provide, at a glance, additional information without connecting a 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 hours of use and expected lifespan based on usage, functions that are 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 metal housing at 3.1 in. x 2 in. x 4 in. deep, U.S. manufacturing, 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, Smart Power is protected against an output short or an overload with automatic recovery. UL 508, UL 1310 Class 2, CSA Class 1, Div 2 ratings are pending. Additional versions, for 120 W, 150 W, 200 W, and 240 W, are coming soon.
Vikram Kumar, vice president, AVG Automation tells Mark T. Hoske, CFE Media, some of the attributes of the new AC Autotech Smart Power field programmable power supply from AVG Automation. The power supplies include built-in displays for current and voltage readout and pushbuttons for setting current limit. They can show operating life remaining, based on usage.
