EPCOS Product Brief 2011
Power Factor Correction
Grid Analysis Tool MC7000-3 for Three-Phase Measuring
The level of power quality can
sometimes only be proven
after severe failures in the
power supply – i.e. when it is
too late. EPCOS offers an
analyzing tool to avoid wrong
decisions for PFC solutions
right from the beginning. The
grid analysis tool MC7000-3
provides three-phase measuring, display and storage of
electric parameters in lowvoltage grids. It is housed in a
www.epcos.com
compact suitcase. The
attached Windows-based
software allows a user-friendly
visualization of all measured
values. This makes the device
unique compared to others
only providing text display. The
simultaneous graphical display
of various views in different
windows offers a fast and easy
evaluation of acquired data.
The mathematical evaluation of
values can be performed with
various calculation tools for the
compensation system. Based
on these results, a tailor-made
PFC solution or inspection of
an existing one is easily designed and optimized. The
collected data – available in
Excel-format – gives users
further processing options.
Grid Analysis Tool MC7000-3
The collection and storage of data is done with an SD
card included in the delivery (1 GB; usage of a 2 GB
SD card is possible). This allows an easy passing to
Windows PCs. Generally, all data are stored with an
ultra-short interval of 1 second only. Due to the SD
card, no additional read out of the memory storage is
necessary. Featuring an illuminated 128 x 64 graphic
LCD display and a large number of configuration
options for data collection, display and storage, the
innovative measuring and analyzing tool is extremely
flexible and simple to use in the field. Additionally, its
compact design and lightweight suitcase makes it
easy to transport. A further benefit for users is the
availability of not only English, but also German,
Spanish, Russian, and Turkish as menu languages.
Due to the plain language menu as well as the help
menu, the handling of the device is very comfortable
and clear.
