Section 1: GENERAL
The power factor controller BR7000 is the consequent follow-up development of the well
proven series BR6000.
The main distinctive feature is the new 3-phases measuring system. Due to the 3-phases
recording of voltage and current the device allows a convenient usage as grid measuring
device and as power factor controller.
All measuring values can be edited and may be displayed in big letters for easier
readability.
2 interfaces are standard. By means of the comfortable windows-software that is included
in the delivery and by using one interface for a connection to a PC the execution and
evaluation of grid measurements is possible. The second interface can be used for
customer specific purposes.
Used as PF-controller various control modes are available. They allow not only to control
according to the phase with the highest load or the average demand of the phases, but
also to realize a real single-phase control (balancing) or a mix of balancing and
conventional three-phases-control.
All well proven functions of the BR6000-series are available for the BR7000; for example
the control series editor, the automatic initialization etc. For an easy usage the concept of
graphic menu navigation has mainly been adapted. New are amongst others an
integrated help (HELP-button) and the possibility to jump back in the programming menu
by an additional ESCape-button.
The usage of a fully graphic support display allows an additional Oscilloscope-Mode where
the phases (half waves) of voltage and current can graphically be displayed.
