Extech Instruments announces its MA640 600A True RMS AC/DC Clamp Meters + NCV that has a higher accuracy rating then standard RMS meters. Extech Instruments announces its MA640 600A True RMS AC/DC ...

If you measure a DC voltage, and want to get some idea of how “big” it is over time, it’s pretty easy: just take a number of measurements and take the average. If you’re interested in the average ...

Understanding the causes, similarities, and differences between current and voltage distortion will help you pinpoint most power quality problems. When a writer or speaker mentions harmonic distortion ...

This is the second part of a two-part series on the methodologies used to find the short circuit current duties of circuit breakers and fuses. The first part, Short Circuit Current Duties of Circuit ...

The ACA-20RM-ALM series digital, true-rms AC ammeters provide a user-settable over-current alarm and measure/display true-rms, non-sinusoidal AC currents. They are completely self-contained and ...

All buck converters need capacitors on the input. Actually, in a perfect world, if the supply had zero output impedance and infinite current capacity and the tracks had zero resistance or inductance, ...

It is easier to match stepmotors and drives from different manufacturers if you know what each is saying. It's hard to stay up to date when you are floating in a sea of technical jargon. However, it's ...

This article provides an examination of the input capacitor requirement for single- and multiple-channel buck converter voltage regulators. The input capacitor of a buck converter is a critical power ...
