Product Description

Style: 8 Outlet

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.

I don't normally write reviews but after experiencing a major power surge that blew out our electrical panel, I felt the performance of this product should be reported.

First and foremost, this product rocks! With as severe of a surge as we experienced I had nightmares of blown-out electronics throughout our home. The reality is that nothing connected with Tripp Lite surge protectors suffered any damage whatsoever! That is incredible!!! I cannot say the same for the condition of the Tripp Lite surge protectors. The surge protector did its job and gave its life protecting my equipment. Even better still, when I contacted Tripp Lite to report the damaged surge protector, their customer service was stellar; they took down all relevant information and then immediately shipped me replacement surge protectors. Can't beat that; a company that actually stands by their product and honors their warranty.

I am completely sold now on these Tripp Lite surge protectors. I have now ordered additional of their surge protectors to cover items that I didn't previously protect and also to have spares.

This item is a bargain at any price. Consider it like a purchase of insurance; since the manufacturer stands by their product this is a must have investment.

I haven't had the chance to destructively test this yet, however the overall product is great.

-build quality: (Aluminum housing, thick wire, sturdy and tight sockets, held together by 10 screws),
-great design (small plug footprint angled at 45 degrees will never block other outlets, nice wall/bench attachment hangers on the back, and serious look)
-electronics: Inside you will find two PCB's, one for control lights and another for the main protection elements. The main board contains:

-Large movs (9 in total) correctly rated for the application.
-HRC fuse.
-Large filter chokes + common mode chokes.
-1KV rated line filter capacitors, etc. etc.
-thermal detection

The electronic components are not top brands, but all are correctly rated. E.g. the line Capacitor is branded "Carli" which is an acceptable Chinese brand - and even brands like "Bourns" are making most of their stuff in China, so those guys are getting pretty good at this. On the other hand, I am not happy that they depict "blue" MOVs (presumably from Bourns) in the circuit picture on their product page, but use the cheaper Chinese versions in actual products. that is a tad deceptive, but oh well, I guess the marketing guys just couldn't stop themselves from being evil!

The protection circuit topology is simple but follows sound design. The wiring is rated for high current draws and large fault conditions. The earth connections are done correctly and the earth path is extremely heavy gauge. Very very sound engineering. Looking at the circuit, this is probably overkill for small/medium sized appliances, but hey, you can never have too much protection!

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.

This review is being written on Amazon.com 8/6/2011 for the Tripp Lite ISOBLOK2-0 surge protector.

Pro's: metal enclosure, low clamping voltage, high joule rating

Con's: unusual mounting method, bulky, best for vertical outlets

I've used other Tripp-Lite surge protecgtors for many years.

Mounting:
The manufacturer picture does not make it clear how this unit mounts to the wall outlet. As other reviewers have pointed out, the plug on the back of this box is not centered. The box plugs into one of the outlets in a standard wall jack, and the other wall jack outlet is not covered, depending on which outlet you use. The wall cover stays in place, so the surge protector does not mount flush with the wall. A rubber bumper helps keep the box fairly level with the wall. However, the unit still wobbles. The protector is best used on a flush mounted wall jack that is oriented vertically with the protector plugged into the bottom jack. Other outlets, such as horizontal or ceiling mounted jacks (example for a garage door opener), or surface jacks found in some utility areas, wouldn't be the best application. A small bracket helps keep the surge protector in place by attaching to the switch plate cover. However, even with the bracket in place, the surge protector can be removed from the wall jack.

Specifications:
The joule rating (larger is better) is excellent for a small surge protector. The clamping voltage (lower is better) is similarly excellent. The LED indicators for protection present and wiring check are bright and easy to see and interpret.

Other:

A paper sticker on the side of the surge projector states "made in China". Previous other Tripp-Lite model protectors I have purchased were made in USA.

Summary:

The specifications of this protector and reputation of Tripp-Lite for surge protectors make this purchase worth it for me.
