The PF controller BR7000* is a folllow-up development of the PF controller BR6000-series, featuring two devices in one: it can be used as a controller as well as a grid measuring tool. The BR7000 offers 15 relay outputs for the steps and three message/ alarm relays. Due to the possibility of programming, the 15 outputs can be used for a broad range of application, for example.
  • 15 conventional steps, each for one three-phase capacitor
  • 15 steps for single-phase capacitors, where each output will switch a single-phase capacitor to N (usually 5 per phase, balancing of grid is possible)
  • Mixed operation: 6 single-phase capacitors (2 per phase) for balancing plus 9 steps for conventional compensation (three-phase capacitors)

The controller can be connected to a PC via an RS485 interface. The Windows-based software BR7000-SOFT allows the readout of acquired data. The possibility of graphical display of all values offers a comfortable visualization.
