Network single-phase choke DSO-220-32 (32A 1x220V 0.91 mH)

DSO-220-32 Line Choke is a highly reliable AC input reactor designed for single-phase 220V networks. The primary purpose of this device is to protect variable frequency drives (VFDs/inverters) and other sensitive industrial equipment from the negative impacts of a poor-quality power grid, as well as to protect the grid itself from higher harmonics generated by non-linear loads.

Key Advantages and Functions:

• Reliable Equipment Protection: Limits inrush currents and effectively protects the inverter from sudden voltage spikes in the main supply.
• Power Quality Improvement: Significantly reduces total harmonic distortion (THD), smoothing current and voltage ripples.
• Extended Lifespan: Reduces heat generation and wear on electronic components (especially DC link capacitors).
• Stable Operation: Prevents false tripping of protective automation during brief voltage drops or imbalances.
