Functions and characteristics
E90463
The Power Logic Circuit Monitor CM3250 and CM3350 are high-performance
acquisition and control devices offering numerous measurement functions. They
integrate easily in power monitoring and control systems due to their Ethernet
connections and embedded web server. They are Transparent Ready.
Whether installed at the service entrance, at the head of a switchboard or on
sensitive-equipment feeders, Circuit Monitor units record the electrical parameters of
the installation. They provide the information required to control costs, improve
power quality and reduce equipment downtime.
The CM3350 detects and captures voltage sags and swells that may cause halts in
production.
Applications
Panel instrumentation.
Sub-billing / cost allocation.
Remote monitoring of an electrical installation.
Comprehensive power-quality monitoring.
EN50160 electricity supply compliance checking.
Contract and load curve optimisation.
Metering of other utilities
Characteristics
Detection and capture of voltage sags and swells
Rapid identification of the underlying causes of problems.
Trend curves and short-term forecasting
Rapid trending and forecasting of upcoming values for better decision making.
Acquisition of rms values every 100 ms
Preventive maintenance, e.g. acquisition of a motor start-up curve, etc.
Electricity quality checking in compliance with EN50160
Fast standardised check on the quality of the electricity supplied.
