DATA SHEET
AC POWER MONITOR
(SD Memory Card Type)
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 secondary-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 data 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.
SPECIFICATIONS
Input specification
1. Measurement method:

1-phase 2-wire, 1-phase 3-wire and
3-phase 3-wire
2. Input voltage:
• R ated input voltage: 200V AC
• M easurement input voltage: 20V to 240V AC
• E ffective input volt age (accuracy-guaranteed
voltage): 20 to 240V AC
• A llowable 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-
down is required with a transformer
installed externally.

transformer.
(Note 3) For without voltage measurement, the value
of the voltage and power factor should be
set by the operation key.
