AC POWER MONITOR (SD Memory Card Type) DATA SHEET PPMC-3 The AC power monitor calculates and indicates active power, reactive power, integrated power, integrated reactive power, frequency and power factor through measurement of single or three-phase AC voltage and current, and stores the measured data. Voltage is input directly or via a step-down transformer, and current is measured with a general-purpose current sensor (CT) of secondary-side current of 5A or 1A. FEATURES 1. Readily connectable to existing wiring Because this monitor is compact (48 × 96 × 100) and lightweight, it can be readily installed in individual facilities, equipment, and distribution board with limited installation space. Since a CT of secondary-side current of 5A/1A that is generally used in the field of power measurement can be used and its secondar y-side current can be directly input, a relay CT is not required and wiring can be facilitated. 2.Easy data recording and acquisition For saving and recording measured da t a , a n S D memory card is usable. Data in a long time can be saved. The saved dat a can be loaded and edited with the card inserted in the card slot of a personal computer. Thus data acquisition by SD memory card does not involve placement of communication cables. 3.Collective monitor possible via network Centralized monitoring and control of distributed measurement points can be implemented via an RS485 communication interface. There are two methods selectable; real-time acquisition of measured data with a personal computer and loading of data recorded on an SD memory card into a personal computer.

Y R 3 Y S (Note) Notes in the case where “without voltage measurement” is specified When “without voltage measurement” is specified, the instrument measures current value only. (It is required to set voltage and power factor value with operation keys or via communication function of the master beforehand.) Calculate the power and integrated power from the voltage setting, power factor setting, and the actual current measurement value. It is not suitable for the measurement of the load with large voltage fluctuation or power factor variation, or when these values are not known. To use the instrument for those purposes, specify “with voltage measurement.” 4. General-purpose CT General-purpose CT of secondary-side current of 5A or 1A must be supplied separately.
