Murata Power Solution’s Datel ACA-20RM series are true-RMS responding digital AC ammeters with built-in current transformers.

The ammeters provide direct measurement of the true-RMS values of complex, non-sinusoidal AC currents of between 2A and 50A.

There are 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 50A model features an over-sized split core transformer for simpler installation and accommodate wires up to 4AWG (21.1mm2).
