Chapter 1 Introduction
This manual explains how to use the PMC-53A-E Ethernet Multifunction Meter. Throughout the manual
the term “meter” generally refers to all models.
This chapter provides an overview of the PMC-53A-E meter and summarizes many of its key features.
1.1 Overview
The PMC-53A-E Ethernet Multifunction Meter is CET’s latest offer for the digital power/energy metering
market. Housed in a standard DIN form factor measuring 96x96x88mm, it is perfectly suited for
industrial, commercial and utility applications requiring direct Ethernet connectivity. The PMC-53A-E
features quality construction, multifunction measurements and a large, backlit, Dot-Matrix LCD that is
easy to navigate and user friendly. Compliance with the IEC 62053-22 Class 0.5S and ANSI C12.20 Class
0.2 Standards, it is a cost effective replacement for analog instrumentation and is capable of displaying
4 measurements at once. It also optionally provides an I4 input for Neutral Current measurement, one
0/4-20mA Analog Input for measuring external transducers signal as well as an Ir Input for Residual
Current measurement. With a standard 100BaseT Ethernet port and a RS485 port supporting multiple
protocols, the PMC-53A-E can be easily integrated into Energy Management Systems as well as Building
and Utility Automation Systems.
The meter can be setup through its Front Panel, Web Interface or our free PMC Setup software. The
meter is also supported by our PecStar® iEMS Integrated Energy Management System. Following is a list
of typical applications for the PMC-53A-E:
Industrial, Commercial and Utility Substation Metering
Building, Factory and Process Automation
Sub-Metering and Cost Allocation
Energy Management and Power Quality Monitoring
