I/O filters incorporate the functions of mains supply HF filters and motor du/dt filters in a compact housing. The input filter section designed for high attenuation and low leakage current reduces line-related interference to limit value C1 according to EN 61800-3.
<h2>The ultra-space-saving filters are available in two technical options</h2>
<ul>
<li>Standard series for THD(i) values ≥ 8 %, PWHD ≥ 15 % in output stages of 4 to 460 A</li>
<li>Economy series for THD(i) values ≥ 15 %, PWHD ≥ 38 %, designed on the basis of the requirements of EN 12015 (lifts and escalators) in output stages of 2 to 63 A</li>
</ul>
