The Electric Power Research Institute (EPRI) has completed a performance assessment of the JEMStar II revenue meter from AMETEK Power Instruments. The JEMStar II is designed to accurately monitor power quality. The meter measures steady state power quality and identifies power quality anomalies on electric grids. It detects voltage sags and swells, harmonics, transients, flicker […]

MakeHarvard is a 24-hour hackathon competition open to undergraduate and graduate students from across the nation that register for a chance to get creative and show their skills. “MakeHarvard was […]
Data acquisition software allows thermocouple/voltage measurement without programming
EXLab Express is data acquisition software that is a version of EXLab data acquisition software from AMETEK VTI Instruments. It allows users of the EX1401 Thermocouple/Voltage Measurement Instrument to acquire data without programming. It simplifies instrument configuration, acquisition and data display without sacrificing functionality or performance. Using EXLab Express, users will be up and running […]
APEC 2018 Magnetics Industry session addresses high-frequency issues
The Power Sources Manufacturers Association (PSMA) Magnetics Committee is sponsoring an Industry Session at APEC 2018 covering winding design for high-frequency magnetics. Its goal is to address many of the challenges facing magnetics design in high-frequency switch mode power supply topologies. The session will take place from 8:30 a.m. to 11:55 a.m. on Tuesday, March […]
Linear equation said to optimize LED positioning for energy efficiency
Open up a typical low-cost LED bulb and you may find LEDs positioned willy nilly around a metal heat-sinking plate. It turns out that not a lot of thought goes into LED positioning on many bulbs aimed at consumers. Often the result is a bulb that consumes far less power than an equivalent incandescent device but […]
Exotic magnetics could cut transformer weights from 35 tons to 450 lb.
Novel magnetic materials now under investigation could boost power density, lower losses, increase efficiency, and reduce size and cost in power electronics. One example of what might be possible from such research comes from Southpole Magnetics in Pittsburgh, a company formed by magnetics researchers at Carnegie Mellon University. The firm envisions large-scale, 35-ton transformers redesigned […]
Keysight Technologies receives certification for eCall test emulator software
The Keysight E6951A public safety answering point (PSAP) emulator has been certified by NavCert GmbH. The E6951A is part of Keysight’s E6950A eCall Conformance Test Solution. The certification was awarded Dec.18, 2017. EU-Regulation 2015/758 states that beginning April 1, 2018, eCall in-vehicle system (IVS) functionality must exist in all new types of vehicles in categories […]
Reflowable thermal switch protects power semiconductors against thermal runaway
A particularly compact reflowable thermal switch is designed to provide thermal protection for power semiconductors such as MOSFETs, ICs, IGBTs, TRIACs, and SCRs. Due to their inherent self-reinforcing heat-producing behavior, these semiconductor devices can overheat and go into thermal runaway. The RTS is designed to protect against such overheating by reliably interrupting the circuit precisely […]
PSMA safety & compliance committee to host APEC industry sessions
The Power Sources Manufacturers Association (PSMA) Safety & Compliance Technical Committee is sponsoring two Industry Sessions as part of APEC 2018. The sessions are: “Comparisons and Trade-offs of Integrated Gate Driver Isolation Technologies” (IS04) and “Isolation Topics in Power Supply Applications” (IS09). Both sessions will take place in Room 4 of the Henry B. Gonzalez […]
Safety-isolated LED-driver ICs deliver flicker-free output up to 65 W
The LYTSwitch-6 family of safety-isolated LED-driver ICs target smart lighting applications. The new ICs deliver flicker-free output up to 65 W and feature up to 94% efficiency and as little as 15 mW standby power with configuration options for two-stage or single-stage PFC support. Targeting smart residential and commercial fixtures and low-profile ceiling troffers, LYTSwitch-6 […]
