Metering Devices
Application Description
The Power Xpert Multi-Point
Meter is ideally suited to
handle submetering in low
voltage power distribution
equipment applications such
as distribution boards in
multi-tenant buildings,
comprehensive main and
feeder metering in
commercial/industrial
switchboards or medium
voltage distribution
equipment with the use of
voltage and current
transformers.
The Power Xpert Multi-Point
Meter provides a cost-
effective solution for
residential or commercial
metering installations. Typical
installations include:
●
High-rise buildings
●
Government institutions
●
K–12, universities and
campuses
●
Office buildings
●
Medical facilities
●
Apartment and
condominium complexes
●
Airports
●
Shopping malls
●
Industrial sites
●
Mixed-use facilities
Features
●
Monitors power and
energy for up to 60 current
sensors; space-saving
modular design allows
measurement from 1 to 60
circuits
●
Built-in communication
interfaces
●
Monitors single-phase and
three-phase loads from 120
to 600 Vac
●
Monitors current, voltage,
power factor, frequency,
power and energy
●
Stores extensive energy
profile data for each
metering point; can be
used to identify
coincidental peak
demand contribution
●
LEDs provide status of unit
communication activity and
verify sensor connections
●
Meets rigid ANSI C12.20
accuracy specifications for
revenue meters
●
Three standard digital
inputs and eight pulse
inputs per optional module
to monitor WAGES (water,
air, gas, electric, or steam)
●
One standard digital output
and eight digital outputs
per optional module for
alarm indication
●
Three types of meter
modules to support 10 mA,
100 mA or 333 mV sensors
●
Can be directly mounted in
a UL Listed panelboard,
switchboard or enclosure
●
256 MB of memory in
meter base for up to two
years of 15-minute interval
data (eight years of one-
hour interval data) for eight
demand values up to
60 submeters
Communication Capabilities
With the Power Xpert Multi-
Point Meter’s built-in
communication capabilities,
remote meter reading and
monitoring functions can be
integrated into both new and
retrofit applications.
●
Standard Modbus RTU
●
Optional Modbus TCP /
BACnet/IP / SNMP / HTTP /
SMTP / NTP /SFTP
communications
Software Compatibility
The Power Xpert Multi-Point
Meter:
●
Can be used as part of
an electrical energy
monitoring and cost
allocation system
●
Can be remotely monitored
via onboard Web pages
with Eaton’s optional
Energy Portal Module
●
Is compatible with third-
party software platforms
and interface devices
Configuration
●
The Power Xpert Multi-
Point Meter is fully
configurable using Power
Xpert Multi-Point
configuration software that
can be down-loaded free
from the Eaton website at
www.eaton.com/meters
●
Each Power Xpert Multi-
Point Meter module can be
configured for up to six
metering points in any
combination of single-
phase and three-phase
metering points
corresponding to the
voltage wiring of the meter
base
●
Power Xpert Multi-Point
configuration software
simplifies system
commissioning and
startup; PXMP
configuration software
supports both online and
offline configurations
Easy to Install
●
UL Listed for mounting
inside panelboards (e.g.,
PRL4), switchboards, and
NEMA 12 enclosures
●
Quick connect terminals
for current sensors,
Modbus communications,
and bus voltages make
wiring the unit quick
and easy
