Digital AC ammeters offer analogue
replacement

True-RMS-AC ammeters use low-power bright-red LED displays with easy-to-read full-size 9.4mm-high characters.

Billed as the world's first true-RMS responding digital AC ammeters with built-in current transformers, the Datel ACA-20RM series from Murata Power Solutions provide direct measurement of the true-RMS values of complex nonsinusoidal AC currents between 2 and 50A Ideal for use in the latest computer and telecomms equipment, the compact self-powered single-board modules feature large, easy-to-read LED displays and provide an ideal replacement for older, less reliable, analogue panel meters

The Datel ACA-20RM series comprises 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 (85-140V AC) and 220V (170-264V AC) versions available.

Power consumption is less than 50mA.

The onboard miniature high-turns-ratio current transformers provide an accurate and straightforward way to measure AC load currents.

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

All Datel ACA-20RM series true-RMS-AC ammeters use low-power bright-red LED displays with easy-to-read full-size 9.4mm-high characters.

The self-contained design of the modules enhances reliability and means that no external components are required.

Precision auto-zeroing circuitry, super-stable components and an RMS-to-DC convertor circuit combine to give the Datel ACA-20RM series excellent performance.

A built-in bezel/filter assembly with metal fasteners allows straightforward assembly of the new ammeters into customer applications.

All models use UL and CSA recognised components.

Operating temperature range is 0 to +60C. Request a free brochure from Murata Power Solutions ...
