Tripp Lite?

OP:
 

Let me geek a little more on Tripp Lite.  I have 3-4 of the Isobar surge protectors.  The big plus is the metal housing should be more or less immune to fires started by exploding MOV's, unlike a lot of plastic housed surge strips.  

The bad news of this particular model, as noted by many others, is they do not disconnect when the MOV's are exhausted.   This is a feature many other surge strips have.  That is, when the Isobar can no longer protect your gear it is still on.  Your only indication will be that one of the two green lights goes out.  

For some of course this is a feature.  They want the strip to provide power even if the surge protection isn't working.  

The Tripp Lite models in the wirecutter article have this shut off feature. 

OK, so that's it for Tripp Lite.  Furman units with SMP and Extreme voltage shutdown (EVS) _will_ turn the power off for long term over/under voltage situations.  If you get 200V, that may be too low for a lot of MOV's, but the Furmans will see it and shut down power.  Same for extreme brownouts, which in some cases can melt a switch mode power supply.  So you are safe from actual surges as well as low-grade under/over voltages.   Double check that the Furman unit you are considering has SMP and EVS though, they make many that do not. 

Premium Safety Features

Automatic shutoff permanently cuts power to outlets if protection circuit is incapacitated, preventing equipment damage and indicating replacement is required

Tripp Lite series Isobar 8-Outlet Surge Protector

 Internal thermal fuse protection prevents MOVs from exploding. 

Kills power to all outlets.

Safe Thermal Fusing Prevents unsafe conditions during extreme extended over-voltages and catastrophic occurrences

ISOBAR6ULTRA

Same protection here.

I have three of these.( older units I’ve had for a while.) Two I use on my H/T system. One on my computer. 

As for the H/T audio system the SPD does require some burn-in time. My guess is, it’s because of the filtering circuitry.

In regards to Isobar surge protectors, I stand corrected... but!! It seems that this was a change I was not aware of.  My bad for not keeping current. 

Based on help from ChatGPT, it seems Isobar models around 2015 did NOT have the shutdown feature, but Wirecutter by 2022 is praising them for including them. 

So thank you for the correction, and if you have older Isobar models you might want to check the specific model number against the product manual.  

Even so, you might want to consider the Tripp Lite TLP1008TEL as a better alternative because of it’s lower let through voltage according to Wirecutter. 

Those $50 units are really hard to say no to, but for anything audio the extra $110 for the Furman PST-8 should be considered. 

FWIW, I bought my Tripp Lite ISOBAR6 ULTRA SPD/conditioners in 2020.  They have the fuse protection. I personally would only buy new factory fresh SPD/Power Conditioner. Never used or reconditioned.            

FWIW, it should be noted that Amazon.com is not on the Furman authorized dealers list. If buying through Amazon make sure the dealer selling the Furman products on Amazon is an authorized Furman dealer.

I think the same is true for Tripp Lite / Eaton products as well.
