Passive Harmonic Filter

The introduction of power devices such as variable frequency drives in many areas have resulted in great improvement in energy saving technologies. These devices however, have strongly nonlinear absorptions generated by distorted current waveforms. This may cause various problems within a user’s company. 

Providing a solution to improve power quality, Enerdoor proudly offers a range of passive harmonic filters for harmonic currents available up to 300 A with voltage up to 480 Vac. 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.
