Harmonic Filters

Enerdoor offers a range of passive harmonic filters for harmonic currents available up to 300 A with voltage up to 480 Vac. Together, Enerdoor and Finmotor have more than 20 years radio frequency interference experience and have developed the harmonic filter series to solve harmonic disturbance and power quality issues by compensating current harmonic and power factor correction.

Enerdoor Harmonic Filters by GD Rectifiers

The FINHRM and FINHRM2 passive harmonic filters offer different levels of attenuation to provide the market with the best compromise to meet the EN61000-3-2, EN61000-3-12 and IEEE519 International Standards. Custom harmonic filters are available for voltage up to 690 Vac.
