When used in conjunction with an Enerdoor filter series, this combination ensures RF protection for equipment in any environment.

The FIN730 and FIN740 filters reduce EMI interference in the 30 kHz to 10 MHz frequency range. The FIN230 filter has a resonance frequency of 150 kHz and provides a large interference reduction in the frequency range between 50 kHz and 5 MHz.  Enerdoor parallel filters provide protection for variable frequency drives, SCR, controllers, and other electric equipment.

DC Filters

DC Filters were designed specifically for the photovoltaic industry and offer a current range from 5 to 3000A with nominal voltage up to 1000 VDC. The FIN1220 and FIN1520 models, installed between PV inverters and solar panels, reduce EMI interference in the DC power line. The FIN1220.0V and FIN1520.0V models offer the possibility of ground connections separated from the virtual zero point. This is particularly useful for critical networks on the protective earth conductor.  Custom DC filters are available upon request, contact GD Rectifiers for more information.
