multicomp F144-...-2 - reactive power controller

KBR reactive power controller multicomp F144-...-2

Reactive power controller - multicomp F144-…-2

The microcontroller-controlled multicomp F144-…-2 records all network data relevant to the control of small facilities via A/D transformer inputs. After calculating the required compensation power to achieve the desired target cos φ, the available capacitor stages are automatically switched on or off with a few switching operations.

The multicomp F144-…-2 switches capacitors of the same powers in circuit switching. Programming is menu assisted and performed with two buttons. Facility-specific values are stored in a non-volatile memory. Each stage can be switched individually via the built-in manual-0-automatic function.

Highlights

  • Real reactive power measurement and calculation of the necessary compensation power in 4-quadrant operation
  • Rapid compensation with few switching operations
  • Display with two-line LC display, stage status and recovery
  • Control logic always circuit switching for the same stages
  • Manual 0 automatic switch separately programmable for each stage
