Passive harmonic filters are recommended for single drive applications and sized by the total current. This series is available up to 800A with nominal voltage up to 480 Vac.
Enerdoor line reactors are available with 3% and 5% impedance and with nominal voltage up to 600 Vac.
Enerdoor passive harmonic filter series is available up to 800A with nominal voltage up to 480 Vac. Custom filters are available with voltage up to 690 Vac. This series features different levels of attenuation offering the best solution to meet the EN61000-3-2, EN61000-3-12 and IEEE519 International Standard requirements.
As a standard, the FINHRM5 offers a current range up to 800A and the FINHRM up to 200A. The typical THDI reduction is <5% for the FINHRM5 and <15% for the FINHRM. Neither filter is effected by network impedance. This series is designed to guarantee a power factor greater than 0.9 considering an initial value of 0.7. An additional external capacitor to improve power factor correction may be included, as required.
Enerdoor passive harmonic filtering solutions improve flicker emissions and reduce the effects of voltage dips under 5ms on the machine's performance.
