Product Description

Color: White

For more than 20 years, America's leading companies have trusted Tripp Lite's Isobar Premium surge and noise suppressors to protect sensitive computer, networking and telecom equipment. With more than 18 million satisfied customers, the Isobar remains the world's #1 selling premium surge suppressor. Loaded with a generous combination of high quality components, near indestructible all-metal case and unique noise filtration system, the Isobar offers the highest level of protection attainable in a multi-outlet strip. Robust surge suppression circuits with sine-wave tracking offer extreme levels of protection against the heaviest surge conditions exceeding IEEE 587 category A & B specifications and reducing 6,000V test surges to harmless levels under 35 volts. Isobar's unique protection system combines large toroidal chokes, ferrite rod-core inductors, HF/VHF capacitors and multiple layers of metal oxide varistors into exclusive isolated filter banks that remove EMI/RFI interference, even noise generated by other pieces of connected equipment. ISOBAR8ULTRA offers 8 outlets arranged in four filter banks to prevent system crashes, reboots and performance problems common as noisy system peripherals are powered off and on. Surge suppression rated at 3840 joules/97,000 amps offers network-grade protection. Widely spaced NEMA 5-15 outlets accommodate up to 4 large transformer plugs without blocking outlets. Diagnostic LEDs confirm power availability, line fault and protection status. Includes 12 foot AC line cord with space-saving angled input plug, keyhole mounting tabs and a set of 4 child safety covers.

Purchased this Surge Protector for additional computer appliances, I own already 3 Tripp Lite Surge Protectors and they have proofed to be the perfect protection. I like about them that they are built in a robust metal housing, have a flat wall plug (so they fit perfectly behind furniture) and Tripp Lite gives you lifetime warranty/replacement - I went through it and their service is exceptional, read below if you want to know more.

I had a very nasty experience a month ago when the transformer for our apartment building blew up... there was a short spike in the power supply which roasted most large kitchen appliances and a few other things in my home. Luckily I had installed Tripp Lite Surge Protectors for my TV set as well as for all my computer peripherals - the Surge Protectors took the hit and protected all things behind them.

Now the best thing and why I would always go again with Tripp Lite; After the incident I called Tripp Lite to find out if I can reset the surge protectors, they told me at the phone that the spike must have been to much and that I need new ones. At that moment I already was thinking to go and shop, but they actually asked me for my address, the serial number of the surge protectors and hey 3 days later I had brand new replacements in the mail!!! That is the customer service we all love!

Tripp lite has a great warranty, we purchased one, got struck by lightening. It saved my computer equipment, but burnt the protector. Tripp lite replaced it free of charge. I've had others on other electronic equipment in the house that have not lasted or protected as well. I'll buy tripp lite after this for all my valuable equipment.

The Isobar is a much better built alternative to the run-of-the-mill powerstips available at most electronics stores. Not only is it a very good surge protector, but it will also help filter and isolate your components which can sometimes help performance.

If you've ever noticed a "pop" through your speakers when an appliance in your house turns on, or if you sometimes get a humming noise, the Isobar will most likely solve that for you. It is a much better solution to a ground loop than using a cheater plug (which is not always safe). Plus the line fault indicator might point out a problem you never knew you had in your wiring.

Can't beat it for the price, and can't beat it for much more than the price. A great pickup for the home or office.

I can't really review on it's surge protection until surge happens.

But one thing I can share with people is that this surge protector filters EMI noise so treadmill motor won't trip AFCI circuit breaker. I have a treadmill with 12 amp motor in 15 amp AFCI circuit. Treadmill was keep tripping the breaker even though motor wasn't pulling more than 12~13 amps. Later, I researched online and some people suggested using a surge protector with EMI filter and mentioned this product.

Treadmill is working beautifully and it hasn't tripped the breaker since then.

Edit, 3/19/14: bought two more of these. Have had many storms and outages since this review. Happy camper.

I'm a Panamax fan, but the recent Panamax models have opted to make a screwball side-plug design which WASTES SPACE.. so I reluctantly had to pick another brand. The only two others I trust are Belkin and Tripp-Lite, since I already have both, and they've saved my equipment many times. (I seem to experience a storm or other outage at least once a month for over 20 years, no matter where I've lived.)

But the Belkin, doesn't specialize in filtering out line noise; Tripp-Lite, does. So, this Isobar, which I just bought here at Amazon, is just like my other one, except larger and more powerful. It WILL accommodate a large adapter -- maybe not all versions. I have an old ZIP parallel power supply, which is the largest adapter I own. It will fit without obscuring the plugs beside it, though barely. Most other adapters are smaller than the Zip, so should fit. Pick the outermost plugs on the ISOBAR (or any other surge suppressor), see if that works. If it doesn't, get a top-priced Belkin model that has good reviews. BE SURE to check the reviews, as not all Belkin models are good. (I bought one recently that I returned to Amazon because it had serious issues with the power on/off switch that reviewers reported.)

NEVER scrimp on cost with a surge suppressor. ALWAYS get the best model you can afford. Having said that, you don't need to buy more protection than you need. But never settle for a power strip alone, and never settle for a lower-priced knock-off.

The Isobar shines in two ways: a) eliminating line noise, and b) sensibly deciphering a real threat from mere variance. Look at the other reviews here about treadmills.

Thank you for your feedback and I am pleased that you are satisfied with your ISOBAR! I wanted to address your comments regarding the insurance. The ISOBAR8ULTRA comes with $50,000 Ultimate Lifetime Insurance, meaning Tripp Lite warrants, for the lifetime of the product, to repair or replace directly connected equipment that is damaged due to power transients while properly connected to the ISOBAR8ULTRA. The maximum payout for the ISOBAR8ULTRA is $50,000. You can find the complete details of our insurance policy on our website. Thanks again.

...everyone says Tripplite stuff is supposed to work! It's a substantial and heavy piece of equipment with a classic and plain, no-nonsense design. The detailed technical diagrams and explanations on the outside of the box is an encouraging sign; it shows that this company is using substance to target literate and intelligent consumers unlike a company such as Monster which (like Bose) just lives off its marketing hype.

I chose this for a new flat screen HDTV and BluRay player. I know it's not the "Home Theater" designated Isobar model, but didn't want to pay an extra $30-40 just for that...I figure this will do the job. Surprisingly, it does seem to have cleaned up the TV's antenna reception a little, by perhaps 10-20%.
