AC True-RMS Ammeters
The new ACA-20RM series are the worlds 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 modules are powered from either 120V (85-140VAC) or 240V (170-264VAC). Power consumption is less than 50mA.
