MURATA POWER SOLUTIONS ACA-20RM-4-AC4-RL-C Digital Panel Meter, LED, 3-1/2 Digits, AC Current, 0A to 50A

The ACA-20RM-4-AC4-RL-C is a 3-1/2-digit true RMS AC Ammeter with built-in current transformer. It is the worlds first digital AC ammeter to incorporate a built-in current transformer (CT) to directly measure the true RMS value of complex, non-sinusoidal ac currents from 2 to 50A, no bulky and expensive 5A "donut" CTs are required. Operation and setup is straightforward, simply pass the load-carrying wire through the on-board CT, apply power and the ammeter is fully operational. It is totally self-contained, no external components are required. Power consumption from a nominal 120 or 220VAC supply is less than 50mA. Precision auto zeroing circuitry, super-stable component and a 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.

• Built-in CTs provide true RMS values of complex waveforms
• Perfect for measuring AC current in IT applications
• Split-core CT for easy installation
• Large, easy-to-read, red LED display with 0.37" digits
• Reliable single-board construction
• Digital replacement for analogue meters
