Murata Power Solutions’ ACA-20RM-ALM Series digital ac ammeters accurately display
the true-rms value of non-sinusoidal ac currents and provide a user-settable, over current
alarm function. When the preset over current level is exceeded, the LED display continu-
ously ?ashes from high to low intensity. All models are totally self-contained—no other
user-supplied components are required. A built-in current transformer greatly simpli?es
most ac ammeter applications: just pass the load conductor through the built-in current
transformer, apply ac power, and the ammeter is fully operational.
Two input ranges are available: 0-30.0 Amps, or 0 to 50.0 Amps, both with 0.1A resolu-
tion. The 50 Amp model features a convenient split-core type current transformer which
can be clamped around insulated live conductors. 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. Super-stable components and an rms-to-dc converter
circuit combine to achieve excellent performance when measuring the complex, non-sinu-
soidal, ac currents found in today’s computer/telecom equipment.
All ACA-20RM-ALM Series true-rms ammeters feature full-size, 0.37 " (9.4mm) high,
3? digit, bright red LED-displays and a built-in bezel/?lter assembly that includes metal
fasteners. They are also panel cutout compatible with MPS’s DMS-20RM Series of rms-
reading ac voltage monitors, making ACA-20RM-ALM ammeters the ideal upgrade for
today’s sophisticated instrumentation.
