Packet Power™ Wireless Current Monitoring Module Manual

Introduction

Current Monitoring Module Overview

Monitoring Capabilities

The CMM provides current monitoring for up to six separate conductors using externally

connected current transducers. It also provides a reading of the ambient temperature within

the CMM enclosure. The device is powered by a 5 VDC source which can be from the

available “universal voltage micro power supply” or another compatible 5 VDC source.

Communication

All data communication for the CMM is wireless. This includes firmware updates. The CMM

incorporates Packet Power’s advanced zero-configuration wireless mesh networking

technology to wirelessly transmit current measurement data to the wireless Gateway module

and forwarded to remote data monitoring and analysis systems.

Enclosure

The CMM is designed to mount directly onto existing electrical enclosures using a 1.0” NPT

hole. In order to provide a reliable radio connection, the CMM is equipped with an internal

radio antennae fully encased within the enclosure. To allow proper radio operation, the

CMM must be housed such that the top portion of the unit is not fully enclosed in a metal

housing. Current transducers and the power supply are connected to a remote interface

board that is linked to the CMM via a ribbon cable connector terminating on the back side of

the CMM. The CMM must be housed in an enclosure that prevents access to the terminal

strip and wires. The CMM is certified as a UL modular device.
