This thread reminds me of a surge protector question I have.

I have a Tripp-LIte surge protector

https://www.tripplite.com/isobar-4-o...es~ISOBAR4220/

It has two "filter banks": one marked (50db) and the other (75db).
What do those number mean? Different levels of surge protection?


The Isobar has internal barriers (isolated filter banks) that prevent line noise from causing A/V distortion, computer lock-ups, data errors and similar problems. Filtering is accomplished by combining toroidal chokes, ferrite rod-core
inductors, HF/VHF capacitors and layers of metal oxide varistors into isolated filter banks that remove EMI/RFI interference.
