AC Ammeters feature built-in current transformers.
April 17, 2008 -
Available in 5 models, ACA-20RM Series provides direct measurement of true-RMS values of non-sinusoidal ac currents from 2-50 A. Self-powered, single-board modules offer choice of either 120 or 220 V nominal operation. Consuming less than 50 mA and operating from 0-60°C, meters include red LED displays with 0.37 in. high characters, precision auto-zeroing circuitry, RMS-to-DC converter circuit, and built-in bezel/filter assembly with metal fasteners.

Murata Power Solution's new Datel ACA-20RM series are the world's first true-RMS responding digital AC ammeters with built-in current transformers (CTs). They are able to provide direct measurement of the true-RMS values of complex, non-sinusoidal AC currents of between 2A and 50A. Ideal for use in the latest computer and telecom equipment, the compact, self-powered, single-board modules feature a large, easy-to-read LED display and provide an ideal replacement for older, less reliable, analog panel meters.
The Datel ACA-20RM series comprises five models with current ranges of: 0 - 0.2A (0.1mA resolution), 0-2A (0.001A resolution), 0 - 20A (0.01A resolution), 0-30A (0.1A resolution), and 0 - 50A (0.1A resolution). The modules are self-powered with both 120V (85-140VAC) and 220V (170-264VAC) versions available. Power consumption is less than 50mA.
The on-board, miniature, high-turns ratio CTs provide an accurate and straightforward way to measure AC load currents. The 50A model features an over-sized split core transformer to ease installation and accommodate wires up to 4AWG (21.1mm2). All Datel ACA-20RM series True-RMS-AC Ammeters utilize low power consumption, bright red LED displays with easy-to-read full-size 0.37in. (9.4mm) high characters.
The completely self-contained design of the modules enhances reliability and means that no external components are required. Precision auto-zeroing circuitry, super-stable components and an RMS-to-DC converter circuit combine to give the Datel ACA-20RM series excellent performance.
A built-in bezel / filter assembly with metal fasteners allows straightforward assembly of the new Ammeters into customer applications. All models use UL and CSA recognized components and have overall dimensions of 1.826in. (46.38mm) X 1.280in. (32.51mm). Operating temperature range is 0ºC to +60ºC.
