DC-AC Inverter Common Mode RFI/Noise Filter Kit for DC in and AC OutputProduct DetailsMPN: RFI-INVERTERType: NEWCountry/Region of Manufacture: United StatesFilter Power Rating (PEP watts): n/aRFI Suppression Range (MHz): 150 KHz - 10 MHzTypical Use:: DC-AC switch mode inverters common mode noise suppressionThe RFI-INVERTER is a common mode noise filter set which filters both the DC input and AC output of DC-AC inverters. These filters effectively isolate the DC power cord and AC output cable from acting as antennas for the internal switching power supply. The filters suppress RFI from 150 KHz to 10 MHz. Simple to install on cables without any device modification. DC filter is a ring and AC output filter is a snap on with 1" inside diameter hole.
For larger cables use the ACCF-3 and DCCF-3 ring filters with 3" inside diameters and use multiple turns on each cable for best results.
AC power strip shown in picture NOT INCLUDED - this is user supplied and shown for illustration of filter installation.

Christmas lights or yard lights with switching DC power supplies are often the RFI source and a clamp on ferrite bead on the AC AND the DC side feeding the lights is needed to help suppress the switching power supply RFI noise. Suitable snap on beads are FSB31-1/2 for the 1-250 MHz range.
We have also had reported wireless HDTV boxes, and FOSCAM and AMCREST security camera systems causing RFI to garage door remote openers. Use our Garage Door Opener RFI kit to suppress the interference to the opener (VICTIM) – you need one kit for each opener. Maximize the distance from the camera to the openers may also help. Additionally shield cable to the garage door sensors may be needed depending on severity of the camera RFI.
Obvious Tech Note: make sure your remote batteries have enough energy to activate the GDO or the signal they transmit may not be large enough to over ride the RFI signal, but a fresh battery may be able to overcome the weak RFI source and allow the GDO to operate correctly.
