PowerMonitor 500 Unit Overview
About the PowerMonitor 500
Unit
The PowerMonitor™ 500 unit is an AC power monitor with a built-in advanced
configuration system and LCD data display. The unit is designed for
measurement of electrical parameters in various three-phase, single-phase
(2-wire European), and split-phase (3-wire North American single phase)
circuits. The unit modular housing can be mounted in a panel that provides IP65
degree protection from the front. The power monitor can be provided with
analog or digital (relay) outputs. These outputs can be selected to output a pulse
proportional to the real and reactive energy that is measured, or to annunciate
alarms. The instrument can also be equipped with a serial RS-485/RS-232 port
or an EtherNet/IP port.
Equipped with an optional communication port, the unit communicates power
and energy parameters to applications, such as FactoryTalk® EnergyMetrix™
software. The power monitor works with these software applications to address
these key customer applications:
•
Load profiling - log power parameters such as real energy, apparent power,
and demand, for analysis of power usage by loads over time
•
Cost allocation - report actual energy cost by department or process to
integrate energy information into management decisions
•
Billing and sub billing - charge users of energy the actual usage cost rather
than allocating by square footage or other arbitrary methods
•
Power system monitoring and control - display and control power flow and
energy utilization
