Product Details
MPN: RFI-INVERTER
Type: NEW
Country/Region of Manufacture: United States
Filter Power Rating (PEP watts): n/a
RFI Suppression Range (MHz): 150 KHz - 10 MHz
Typical Use:: DC-AC switch mode inverters common mode noise suppression

The 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.

50 ohm coax to 75 ohm balanced output baluns are useful for low (< 1 wavelength) dipoles exhibiting 75 ohm characteristic impedance or for matching to balanced ladder line whose endpoint impedance is near 75 ohms.

50 ohm coax to 75 ohm CATV coax connections are easily done with a 1.5:1 unun with SO-239 connectors on input and output.  Likewise 50 ohm coax to unbalanced verticals or loads near 75 ohms can be matched with a 1.5:1 unun.
