North Atlantic Industries, Inc. (NAI) Modified COTS and custom power supplies worldwide, announces the availability of the VPX55-3HU 3U, VPX Power Line Conditioner with Holdup. The VPX55-3HU is a 500 watt, DC/DC power line conditioner that protects downstream DC/DC converters from MIL-STD 704B through F transients, low voltage conditions and power interruptions, and provides up […]
“(Almost) Everything You Wanted to Know about Capacitors” workshop to be pre-APEC event
The Power Sources Manufacturers Association (PSMA) and the IEEE Power Electronics Society (IEEE PELS) are jointly sponsoring an all-day workshop titled, “(Almost) Everything You Wanted to Know About Capacitors But Were Afraid to Ask,” on Saturday, March 3, 2018, the day before the start of and in the same venue as APEC 2018 at the […]
How cooling fans earn different IP ratings
Cooling fans designed for environments more harsh than an office building may carry a special IP rating that designates resistance to different levels of dust and moisture. Here are a few basics when it comes to the differences between fans made to different IP ratings. The IP in IP rating stands for ingress protection. IP […]
Rack-mount hot-swap supplies available with LAN interface modules
LAN (Local Area Network) modules work with HFE series 1.6 kW and 2.5 kW rack mounted, hot swap power supplies. These optional modules allow remote monitoring, status check and programming through a number of standard protocols, supporting VISA (Virtual Instrument Software Architecture). The LAN option is suitable for computer networking, telecommunications, test and measurement and […]

Magnetically shielded SMD power inductors for high inductances
Metal Hybrid Inductors, known as the CDMT40 series, offer more than double the inductance values of earlier introductions while maintaining the same small footprint. A newly developed composite material draws on the special qualities of two different metals in the mold structure to provide magnetic shielding, small size, and high current ratings. The CDMT40D40 also […]
Radial-leaded electrolytic caps feature ultra-low ESR, long life, wide temperature range
The NEW FS Series Radial Leaded Aluminum Electrolytic Capacitors made by Panasonic features extremely high capacitance, long life and low ESR, all in a significantly smaller case size. The FS Series provides space reduction and allows for a reduced number of capacitors on the board. Low ESR and high ripple current in the FS Series […]
Gallery: Technical highlights of the Electric & Hybrid Vehicle Technology Expo
Electric & Hybrid Vehicle Technology Expo & Conference kicked off this week in Novi, Mich. near Detroit. Billed as a forum for electric, hybrid and plugin hybrid vehicle technology, it showcased technological developments along the supply chain including electrical powertrains and components, battery management systems, materials and equipment. Here are a few of the more […]
What is the difference between energy harvesting and energy scavenging?
During the first decade of this century, advances in several disparate technologies set the stage for a substantial rise in autonomous and semi-autonomous remote intelligent-node deployments that continues to this day. This trend arose in applications as different as hydrological surveying, transportation tracking and management, and machine health. It also has kicked off a flurry […]
Choppy waveforms confuse electronic energy meters
Some electronic power meters as used by utilities can give readings that are more than five times higher than actual energy consumption when the measured waveform is nonsinusoidal. So say researchers at the University of Twente (UT) in the Netherlands who collaborated with the Amsterdam University of Applied Sciences (AUAS) to measure the accuracy of […]
