Ordering Information

The PXMP Meter system offers the flexibility to be used in a variety

of applications and can be customized, using the modular compo

nents, to fit most installations .  Table 1 lists the modular components

available for the PXMP Meter system

Metering Compatibility

Direct Mains Voltage Monitoring with the PXMP Meter is possible

up to a system maximum rating of:

• 480VL:G (corner grounded Delta)

• 347VL:N & 600VL:L maximum for Wye applications

• 480VL:G & L:L maximum on grounded Delta applications

Higher Voltage ratings or floating Delta applications will require the

use of interposing potential transformers to stay within the PXMP

maximum voltage ratings .

PXMP Load Current measurements are directly compatible with

current sensor (instrument transformers) outputs in three ranges of

secondary maximum outputs by using matching range PXMP Meter

Modules:

• 10 mA;

• 100 mA; or

• 333 mV .

Various meter modules can be mixed and matched in a single PXMP

Meter Base with support for split core sensors, solid core sensors,

or both based on the circuits that need to be metered .  In addition,

PXMP Pulse Input Modules (PXMP-PIMs) can be installed into a

PXMP Meter base for pulse metering from other electricity, gas,

water, air, or steam meters .

Output modules are available for either remote control over Modbus

or automatic control by the PXMP Meter based on customer config

ured threshold triggers .  A PXMP Energy Portal Module (PXMP-EPM)

is available that can make metered data available to individual ten

ants via an embedded WEB server .  The Energy Portal module also

supports a variety of protocols including Modbus TCP, SMTP, SNMP,

SFTP, HTTP, HTTPS, and more .  In addition to Ethernet, the Energy

Portal Module supports an optional dial up telephone connection for

interface with remote billing software .  A Touch Screen Display is

available for local display of metered data from any circuit .

Product Overview

The Eaton Power Xpert® Multi-Point Meter (PXMP Meter) offers a

highly modular approach to high density metering applications in

electrical power distribution equipment .  The PXMP Meter is com

patible with most 3-phase industrial, commercial, and single-phase

residential low voltage electrical power systems .  Typical applications

include feeder and branch circuit load monitoring found in switch and

panel boards, however higher level voltage metering is possible with

interposing load sensors and potential transformers .

The modularity of the PXMP Meter allows this metering system to

be customized to suit each metering installation based on the number

and type of circuits to be metered .  Up to 10 different PXMP Meter

Modules (PXMP-MMs) can be mixed and matched within a PXMP Meter

Base (PXMP-MB) to accommodate a total of up to 60 poles of metering

channels from a variety of 1. 2. and 3 pole loads .

Features & Benefits

• Automatic PQ Analysis captures harmonics, sags, swells, and

subcycle disturbance transients to protect mission-critical IT

equipment and infrastructure like motors, capacitor fuse banks,

transformers and conductors from damage.

• Minimize business interruptions by automatically diagnosing

disruptions to sensitive, mission-critical processes with Setpoint

Learning and pre-configured ITIC and SEMI-F47 triggers to get

started again as quickly as possible.

• Industry’s highest ANSI class accuracy, along with high-fidelity

512 or 1024 samples/cycle measurements on current, voltage,

power factor, and other comprehensive power metering param

eters such as harmonic distortion, flicker, crest factor, K-Factor,

and more.

• Circuit monitoring to improve the life of your infrastructure and

equipment investments: watching for harmonics, voltage tran

sients, and other potentially harmful power events.

• Circuit loading can be monitored with voltage and power levels,

power factor, energy usage, I/O status, and power quality

measurements, as well as harmonic plots, disturbance and tran

sient waveforms, and an ITIC disturbance summary screen.

• Power quality capture and analysis of multi-channel waveforms

and other information to support in-depth statistical analysis.

Applications

• Protect the integrity of your most important systems with Eaton’s

patented Power Quality Health Index, which provides an intelligent

read-out of circuit health based on statistical analysis of power

quality events and disturbances.

• Diagnose PQ problems with +/-0.1 ms sequence of events recording

that uses PTP for high precision time stamping. This is 10x better

than the industry benchmark.

• Multichannel dual plotting allows comparisons of current and

voltage channels at high resolutions to easily explore the effect of

large loads on your system with a clarity never seen before.

• Investigate power quality disturbances by severity, time or occurrence

with Event Analysis Calendar, graphical ITIC/SEMI-F47 analysis, and

sequenced events – part of the unique web based analysis suite available

on board PXQ.

Overview

Eaton’s Power Xpert Quality (PXQ) event analysis system is a

state-of-the-art power quality monitoring instrument designed

for power distribution assemblies like low and medium voltage

switchgear and switchboards. Compatible with industry power

quality standards (such as IEC 61000-4-30 Class A and IEEE

1453), this ANSI C12.20 Class 0.1 metering device offers advanced

analytics at the edge that simplify troubleshooting of power-quality

events. A highly modular approach provides maximum flexibility

to configure a metering system that can grow with the application

it is monitoring.
