resolution), and 0-500 amps (1A resolution). Two power supply options are available:
85-140V (47-63Hz), and 170-264V (47-63Hz). Power consumption from a nominal 120V
or 220V ac supply is less than 50mA. And, precision auto-zeroing circuitry, super-stable
components, and an rms-to-dc converter circuit combine to achieve excellent performance
when measuring the complex, non-sinusoidal, ac currents found in today’s computer/telecom
equipment.

They are also panel-cutout compatible with Murata Power Solutions’ DMS-20RM Series
of rms-reading ac voltage monitors, making ACA5-20RM ammeters perfect replace-
ments for older, less reliable, analog voltmeters and ammeters in today’s sophisticated
instrumentation.
