Chapter 1 Introduction
This manual explains how to use the PMC-592 MCPM Multi-Circuit Power Monitor.
This chapter provides an overview of the PMC-592 and summarizes many of its key features.
1.1 Overview
The PMC-592 MCPM is the ultimate solution for PDU, LVDB and Load Center application that require
multi circuit monitoring. Housed in a compact metal enclosure, the PMC-592 is perfectly suited for
applications that require high density metering. The PMC-592 features quality construction with
multifunction and high-accuracy measurements, two Mains Inputs (each with 3 Voltage and 4 Current
Inputs), up to 84 Branch Circuit Inputs and an optional 7” Touch-Screen HMI. The PMC-592 comes
standard with two Digital Inputs or optionally four Digital Inputs for status monitoring, two Relay
Outputs for control or alarming as well as two RTD Inputs for temperature measurements. The standard
SOE Log records all Setup changes, Setpoint alarms and DI/DO operations in 1ms resolution. With
Ethernet and dual RS-485 as standard feature supporting Modbus RTU/TCP as well as SNMP, the PMC-
592 becomes a vital component of an intelligent, multifunction monitoring solution for Data Center and
Utility applications.
Typical Applications
Data Center PDUs
Clean room LVDB (Low-Voltage Distribution Board)
Load Center Monitoring
Ring Main Unit Metering
Motor Control Center metering
Commercial & Residential LV High-Density Multi-Circuit monitoring
The above are just a few of the many applications. Contact CET Technical Support should you require
further assistance with your application.
