Description
Murata Power Solutions’ ACM20 series AC power meters display the most critical measurements in mains-powered equipment: voltage, amperage, active power (watts), and power factor. A front panel selector-switch provides two modes of operation: a fixed reading of any of the four parameters, or a continuous cycling through all four measurements. An optional model displays line frequency with 0.1Hz resolution. All ACM20 multi-function power meters include built-in current transformers—no other user-supplied components are required.
ACM20 series AC power meters are available in a choice of three input ranges: 0-10A (with 0.001A resolution, 999.9 watts max.); 0-32A (with 0.01A resolution, 9999 watts max.); and 0-100A (0.1A resolution, 26.4kW max.). An 85-264Vac (47-63Hz) operating supply range makes these power meters perfect for worldwide power monitoring applications. And, unlike conventional, average-responding products, ACM20 power meters can accurately display the real power and true-rms current values of triangle waves, square waves, and other irregularly shaped waveforms, with a typical accuracy of ±1% of full scale.

Panel Installaton
All connections to ACM20 power meters must be made after the unit is securely attached to the panel and with all associated load and supply voltages de energized (off), using extreme caution and observing all safety measures applicable to the user’s installation.
Care should be exercised when passing conductors through the power meter’s built-in current transformer L1.
The installed wire positions should be such that minimal mechanical forces are applied to current transformer L1, TB1, or to the ACM20 power meter itself.
In high-vibration environments, it is strongly recommended that adequate strain reliefs be used for all wiring.
Application
Marine Engineering: As the core of the RT-flex series engine control system, it monitors the main engine's speed, temperature, and pressure in real time and triggers alarms in case of anomalies.
Smart Factory: Connects PLCs and various sensors to achieve automated status monitoring and integrated control of production line equipment.
Smart Buildings: Collects temperature and humidity signals to drive energy-efficient operation of air conditioning and lighting systems.
