Axiom Home Page Forums General Discussion Technical Questions Power Line Conditioner?

I missed your post about brown-outs. You need under-voltage protection if your equipment doesn't have it. The Panamax AV-Pro has that and over-voltage protection too.So gather that is good!!

What is the voltage protection rating (VPR) of the whole house surge protector? The VPR is the voltage downstream equipment will be subjected to when the protector operates. Note the Panamax starts clamping at 200V peak but can let through as much as 500V in the 6kV/3kA combination wave test of UL1449. TVs and AVRs will snap, crackle, pop unless they have their own surge protection - and I expect they do for 500V peaks. It is a older unit(2017) can not find any info on it other then HEPD.80 can not find one that looks like it!!



As for limiting current, some, like the Furman, limit the available steady-state current. The Panamax doesn't. As for transient current, I wouldn't expect a device like the Panamax to limit it at audio frequencies. The protection works at much higher frequencies.

Here are the installation instructions and specs for your house surge protector.

That's a heck of a unit and you can definitely trust Schneider Electric products. Unfortunately, the VPR is still very high.

The Panamax will protect from high and low voltages and lower the VPR by 100V as a bonus. But the house surge protector will take the majority of the hit.

And yes, the Panamax makes far more sense than the Furman.
