Murata’s Digital Panel Meters at Digi-Key

From Digi-Key, for more than 35 years, the Murata Power Solutions / Datel offering of digital panel meters has been recognized as the industry's most versatile and affordable meters. While the ACA5-20RM and ACA-20RM-ALM ammeters offer current measurement to 500A, the DMS-20PC and DMS-20RM provide precision voltage measurement from ±200mV to ±200V.
General Purpose Voltmeters
DATEL voltmeters are a good solution for applications requiring a precise readout of AC or DC voltages.
Typical mounting options include 12-pin DIPs and traditional bezel/case assemblies which simplify panel mounting
AC-input options include average or rms-responding inputs
Self-powered, 2-wire models contain only two connections since they are powered directly from the signal they are measuring, making them ideal for new installations or as modern replacements for analog panel meters
Digital options include 3½ or 4½ digit, LED or LCD displays which can be operated from AC (85-264V) or DC (+5V to +40V) power sources
For harsh environments, users can choose from several bezel options that feature rubber gaskets and secure threaded metal fasteners.
Ammeters
For measuring AC or DC currents, DATEL ammeters feature easy set up and installation, and typically require no additional components or user set up. Average responding or true-rms inputs can measure currents up to 100A with a built in current transformer and up to 2000A with external 5A CTs.
AC ammeters with built-in current transformers (CTs) greatly simplify current measurement applications. Most installations require just three connections: two for supplying operating power, and one for the current being measured. All models feature easy-to-read LED displays and sturdy terminal block connections.
DC ammeters are available with built-in shunts capable of measuring currents from 200uA to 20A. For higher currents, models are specifically designed to accept inputs from external 50mV DC shunts, enabling these models to measure up to 2000Adc.
