The Murata Power Solutions ACM20 series Four-Function AC Power Meters display the most critical measurements in AC-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.
