Product ReviewsTripp Lite Isobar Ultra 4 Outlet Diagnostic Surge Suppressor Protector

High Quality - Metal Enclosure - Multiple Surge Suppressors!

I purchased this Isobar Ultra due to its design and specifications. Each outlet has its own circuit to deal with surges. It also has “three” monitor lights keeping you aware of any faults or line voltage irregularities. It’s a rugged, nicely thought out and functional design. A necessary piece of protection equipment for your costly Electronics and microprocessor controlled appliances.Read full review...

THE Best In Power Products!

Tripp-Lite has been my choice of power distribution and equipment protection for years. Out of hundreds of Isobar 8 Ultra strips I've put in service only one sacrificed itself to protect expensive electronics (I have very good power to begin with). They are very ruggedly built and have no issues being re-used multiple times. They are an investment in quality and protection that all "cheap" brands can't come close to. I use them on my computers and A/V system at home as well. I wouldn't use anything else regardless of how good the power is. Won't take a chance!Read full review...

Great surge suppressor with a fine warranty. Make sure its current model!

These are really high quality power strips with excellent suppression built into the unit. Clamping voltage is excellent. Joule rating is some of the highest on the market. Their lifetime warranty is second to none, and hundreds of reviews on line claim Tripp Lite replaced their unit for no cost at all with no hassles, even on very old models. When buying on eBay, make sure you are getting the latest model. They can look deceptively alike, and older models can have lesser protective specifications. Consult the Tripp Lite website if you have any questions. They are very helpful.Read full review...

Be nice to see a 2 pronged variant from Tripplite

Does a decent task at reducing noise from the wall, which is THE REASON why I acquired one. It is perceiveable running audio monitors on idle. I was able to redistribute my power feeds throughout my multimedia system and found THE CULPRIT responsible for the noise; that is the laptop SMPS. I simply removed the said supply off the ISOBAR and no more switching noise, well there is a little but now it is attenuated to where I do not hear it. Good solution for the money, oh for the ISOBAR4 the top right jack seems to be the better and the lower left second best in terms of noise attenuation in case anyone was wondering. Now I am awaiting a laptop SMPS replacement.Read full review...

Tripp Isobar4 Ultra is excellent!

This surge protector replaced another which had broken prongs of the outlet cover broken off inside the receptacle. This was exactly what I needed. Shipping and arrival was quite. You can't beat Isobar's $50,000 equipment warranty, either. Read full review...

It's only perfect

I have two of these, and I will undoubtedly have more very soon. I use them as outlet extenders more than for their surge suppression capability. They are ideal for grouping tools together in my worshops. I know of no negatives. They work, and they work very well.Read full review...
