low voltage capacitors
Advantages:
High Efficiency: Reduce energy losses and penalties from low power factor.
Compact Design: Modular, stackable units for easy installation.
Long Lifespan: ≥100,000 hours at rated conditions.
Low Losses: Typical dissipation factor (tan δ) < 0.2%.
Our low-voltage capacitors are used in conjunction with detuned reactors to reduce harmonic distortion and minimize interference effects on the operation of other loads. Depending on the chosen tuning frequency, some of the harmonic currents will be absorbed by the power capacitors.
