Designed for transportation, telecom, base station and other applications, the VKD1000 series converters are chassis-mounted, and enclosed in a 9.76 × 7.17 × 2.28-inch shielded metal case with a built-in heat sink. They have input voltage ranges of 80-180, 200-400 and 400-800V dc, and output voltages of 12, 15, 24, 28 and 48V dc at up to 1,000W of power. They come with protections against under-voltage lockout, over current, over voltage and over temperature. They are made to work in -25 to 85C environments, but also come in models that work up to -55 to 85C. They cost $490 per unit.
The engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
The age of touch could soon come to an end. From smartphones and smartwatches, to home devices, to in-car infotainment systems, touch is no longer the primary user interface. Technology market leaders are driving a migration from touch to voice as a user interface.
Soft starter technology has become a way to mitigate startup stressors by moderating a motor’s voltage supply during the machine start-up phase, slowly ramping it up and effectively adjusting the machine’s load behavior to protect mechanical components.
A new report from the National Institute of Standards and Technology (NIST) makes a start on developing control schemes, process measurements, and modeling and simulation methods for powder bed fusion additive manufacturing.
If you’re developing a product with lots of sensors and no access to the power grid, then you’ll want to take note of a Design News Continuing Education Center class, “Designing Low Power Systems Using Battery and Energy Harvesting Energy Sources."
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
