specifications features data sheet ppmc-3 ac power monitor (sd memory card type) 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. 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 fo r s av i n g a n d r e c o r d i n g m e a s u r e d d a 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 rs- 485 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. 1. measurement method: 1-phase 2-wire, 1-phase 3-wire and 3-phase 3-wire 2. input voltage: ? rated input voltage: 200v ac ? measurement input voltage: 20v to 240v ac ? effective input volt age (accuracy-guaranteed voltage): 20 to 240v ac ? allowable input volt age: 1.2 times the rated voltage (continuous), 1.5 times (for 10 sec) (note 1) in a 440v, 3300v or 6600v system, step- d o w n i s r e q u i r e d w i t h a t r a n s f o r m e r installed externally.
