True-rms AC Ammeters Feature User-Settable Over Current Alarm

Tue, 05/26/2009 - 6:59am

Murata Power Solutions has introduced a new series of digital AC ammeters with alarm for the measurement and display of complex, true-rms, non-sinusoidal AC currents. The DATEL ACA-20RM-ALM AC ammeters are completely self-contained and include a built-in current transformer to simplify their use in numerous applications. The integral alarm is triggered when the user-settable over current value is exceeded. The red LED display continually flashes from low to high intensity to indicate an alarm condition. Appropriate for measuring currents in sensitive IT and telecom equipment, the DATEL ACA-20RM-ALM series offers two models providing an input range choice of either 0 to 30 A or 0 to 50 A. Both have a resolution of 0.1A and the 50A model features a convenient split core type current transformer that can be easily clamped around insulated live conductors.
