# Four-function AC Power Meters Tout Hertz-reading Capability

Murata Power Solutions has expanded its offering of Datel Digital Panel Meters with two additions to its ACM20 series of Four-Function AC Power Meters. These models are able to able to measure and display frequency in Hertz (Hz) in addition to indicating true-rms AC Volts (V), Amps (A) and Watts (W); existing models display Power Factor rather than frequency. The new additions to the range are the ACM20-5-AC1-R-F-C offering a measurement range of 0 A to 32 A (with 0.01A resolution), and the ACM20-4-AC1-R-F-C that has a 0 A to 100 A range (with 0.1 A resolution). Enhancements to existing models, and also incorporated in the new meters, are UL safety agency approvals, and an increase in the maximum power reading for 100A models from 9999W to 26.4kW. The ACM20 series has a typical full-scale accuracy of ±0.5 percent and unlike conventional average-responding products, accurately displays true-rms voltage and current values of triangle and square waves plus other irregularly shaped waveforms. A universal 85 to 264 VAC (at 47 Hz to 63 Hz) operating voltage allows the compact, rugged, surface mount ACM20 series to be used worldwide.
