On infrequent occasions, I am asked to design a circuit to measure the RMS value of a current or voltage for some kind of power measurement. Since the work I do is hardly unique, I thought some of you ...
Murata Power Solutions has introduced the DATEL DMS-20RM series of voltmeters that can measure the true-rms value of complex ac voltages and, with an input frequency range of 47 - 1kHz. It is ideal ...
AEMC's Sentinel Current Data Loggers are a new line of loggers that record true RMS measurements of current parameters. The current loggers include integral flexible current probes for three-phase ...
The circuit in Figure 1 measures both the true-rms value and the rectified average value of an ac signal. This design uses two low-cost ICs in SOIC packages and consumes only 180 µA of quiescent ...
Murata Power Solutions series of digital AC ammeters have an alarm for the measurement and display of complex, true-rms, non-sinusoidal AC currents. The Datel ACA-20RM-ALM AC ammeters are ...
The company’s family of DATEL voltmeters claim to overcome the limitations of conventional average-responding AC voltmeters with the capability to measure the true-rms value of complex AC voltages.
