You almost never hear of a DC Watt Meter – one just does some mental math with Volts and Amps at the back of one’s head. An AC Watt Meter, on the other hand, can by pretty useful on any workbench.

Abstract: A most important link in the chain of electric energy supply always has been the watt-hour meter. Meters have been developed and improved during more than 50 years; now new material has made ...

The WQ type watt and varmeters include: an electronic measuring unit that converts power into direct current and an indicator - a direct current ammeter with a magnetoelectric measurement system.

Simply rotate the element to read forward or reflected power. The model is a shock-mounted meter with 25, 50 and 100 scales, permitting full-scale power reading from 100 mW to 10,000 W with the ...

Abstract: There are two general classes of large capacity watt-hour meters, alternating-current and direct-current. The meters used for alternating current are almost invariably of the induction type, ...

Unfortunately we do not sell that board, but we do provide the schematic and Gerber files for you to go and get one made on your own. If you are interested in the Gerbers/Layout files, please let us ...

I want to implement a Three-Phase Electronic Watt-Hour Meter Using the MSP430F47197. The IAR Embedded Workbench for MSP430, v. 5.50, Evaluation version was downloaded and I wanted to load the project ...
