The power factor controller PFR-X+ calculates the actual and reactive power in the mains from the measured current and voltage. It also determines if actual power is being consumed or delivered. It identifies the power of the connected capacitor stages and connects or disconnects them in an optimized manner as required by the actual mains conditions. The regulation considers the frequency of changes in the reactive load and follows the principle of rotational switching. This guarantees that optimum power factor correction is achieved with the minimum number of switching operations.
The integrated digital display can show the actual power factor, the mains frequency, the actual tariff, the programmed target power factor, the connected capacitor power.
The PFR-X+ is ready for operation with its preset functions immediately after installation without any modifications or adjustments.
