Part 2 - RFI check on the Clean 13.8 V DC from any power supply or battery with this DC/DC converter

In this video we will check the RFI suppression built in on the DC/DC 13.8 V stabilizer.
The main components used in this project are a RCNUN DC 8-40V a 13.8V 30A Boost-Buck converter and a EMI filter for 25A two stages for high frequency
