Line / Load reactors

MANGOLDT offers a standard product range of 5-in-1 Line/Load reactors for adjustable speed drive applications to ensure trouble-free operation of your facility.

As a reliable solution for adjustable speed drives, AC to DC converters, active front ends and frequency inverters, line reactors reduce harmonic current distortion and absorb voltage transients. They efficiently decrease harmonic currents that flow through facility transformers and onto the upstream power system (network).

The line reactor's impedance can also limit starting and peak currents associated with energizing converters thus protecting your electronics. Additionally, charging peaks in capacitor circuits are dampened. Both effects increase the lifetime of the installation.

The MANGOLDT standard product range offers each line reactor with rated impedance values of 3%, 4% or 5% and is available from stock. Therefore, more than 100 different products are immediately ready for dispatch from Germany, Taiwan, USA and Canada.

MANGOLDT supplies all line reactors as UL listed product with the required certification marks.
