Categories > Surge Protectors > Kensington > Kensington K38218NA 6' 8 Outlets 1080 joule Surge Protector

Rating + 4Rating + 4Rating + 4Rating + 4Rating + 4 Sensible design of outlet layout
Pros: I purchased this mainly for the way some outlets are spread out to accomodate different shape/orientation of device power adapters without blocking neighboring outlets. The price was great too.
Cons: None so far.
Other Thoughts: Yes I would recommend this and yes I would purchase it again if the need arises.

Categories > Surge Protectors > CyberPower > CyberPower B604T 4 Feet 6 Outlets 1350 Joules Essential Surge Protector

Rating + 1Rating + 1Rating + 1Rating + 1Rating + 1 This would make for a simple outlet expansion strip that includes one transformer spaced plug.
Pros: none
Cons: MOV based surge protectors are big jokes that companies play on us by lulling us into a false sense of security. Designed to divert the surge at a certain voltage threshold to either Neutral &/or Ground prongs of a 3-prong outlet but often fail miserably at that.

A surge has both a voltage & current wave and can have fast rise times, but the MOV only acts on the voltage AND not immediately. Until it does, our electronics is protecting the surge protector (sad, true & Ironic)

Per the IEEE a surge traveling on #14 gauge house wiring can be 6000 volts 3000 amps & last up to 50 microseconds. Anything more and the wiring will be vaporized.

When diverted (to the Neutral and/or Ground wires) the surge needs a low impedance return path to the panel, otherwise it will seek an alternate path even if through the electronics we’re trying to protect or any device plugged into the same branch circuit.

Ground is a zero volt reference voltage by electronics and modern appliances. It’s expected to be at zero volts and it wasn’t designed to be used as a place to dump a surge. When a surge is on the ground, strange things can happen: unexplained hard drive crashes, fried motherboards or circuit cards, bad USB ports, premature power supply failures, hum/noise in audio, noise/pixelization in video & the most common: failed HDMI ports. Ground contamination is a big issue.

At 60 Hz (low frequencies) electricity has a low impedance path on the Neutral wire even with several 90 degree turns by the time it gets back to electrical panel. Ideally house wiring should be point to point with no 90 degree turns but often times that isn’t the case. Surges can be very fast (high frequencies) & the house wiring can suddenly represent a high impedance return path, causing the surge to seek another path to ground through the electronics we’re trying to protect.

By way of an analogy, consider a hand gently breaking the surface tension of water and freely moving underneath the water. This is how it is for electricity. Now take the same hand, slam it as hard as you can into the water & you’ll encounter a lot of resistance, perhaps it will feel as if you hit a brick wall. This is how it is for surges. The water is analogous to the house wiring. At some frequency the surge hasn’t got a chance & will seek another path perhaps damaging our electronics in the process. That’s why spikes or transients which are often measured in billionths of a second are least likely to find their way, & often zap our electronics instead.

MOV’s were designed in an age when we didn’t have microprocessors & our electronics was a lot simpler. Circuits ran on higher voltages, slower speeds and chip junctions were rather large. Today we live in a world where we can pack hundreds of millions of transistors on a chip, run at extremely low voltage levels and have chip junctions that are shrinking each year and are even more susceptible to “electronic rust” which happens when we subject the chips to surges. This rust will cause the chip to fail prematurely.

An MOV will eventually fail and the failure mode is smoke, explosion and/or fire. To protect against this, sometimes the MOV is encased in a fireproof material &/or used with a series thermal fuse (physically the two are wedged tightly against each other). When the MOV gets extremely hot, the thermal fuse opens & takes the MOV out of the circuit. Depending on the design, the surge protector will either continue to supply or remove power from its outlets.

Connected Equipment Warranties (insurance) are designed with so many loop-holes or escape clauses for manufactures that it can be very difficult to collect any money from them. You have to buy from an authorized seller, send in the warranty card on time, send the failed surge protector in & if its determined that the surge protector failed, then take the electronics to an authorized repair center to obtain a quote at the consumers expense on how much it would cost to repair the item & what the failure mode was. Once the manufacture reviews the information at their discretion they will either pay for the repair or send you the fair market value of your electronics based on recent successful auctions or local sales. Besides spending hours on the phone you risk loss of personal data not to mention the electronics &/or appliances themselves.

Some companies recognize Ground contamination as a real issue & have resorted to using single mode MOV protection across the Line to Neutral wires only. While a step in the right direction all the problems associated with placing the surge on the Ground still apply. To help some companies include over/under voltage shutdown circuitry but it takes a little time for the circuit to start work & in the meantime your electronics is protecting the surge protector again.

Surge protection is a multi-billion dollar industry growing 5.6% annually & MOV based surge protection makes up an increasingly larger share of that market.
Other Thoughts: MOV surge protectors:

(1) Work on a voltage (not current) thresholds so fast changing (rising surge) currents will pass into the very electronics that one is trying to protect.

(2) Have to wait for a voltage threshold to be reached before they can start to work, in the meantime the surge will pass into the very electronics that one is trying to protect.

(3) Will divert the surge and hope for the best, often times failing (the faster the surge, the longer the surge will linger, the greater the chance the surge will enter into the very electronics that one is trying to protect.

(4) Are sacrificial and no one knows how long they’ll. Manufacturers recommend changing them once a year to ensure protection (questionable as that protection might be). Don’t confuse a sacrificial surge protector with quality.

Lastly, you can’t always count on the status LED to know that you have protection. It’s worth performing a shake, rattle & roll test periodically by unplugging everything from the surge protector, gently shaking & rolling it to see if you can hear something rattling around inside. If you do, chances are it’s one or more of the MOV’s that have exploded or caught fire.

The best place to provide initial surge protection is at the service entrance. For electrical outlets it’s in the mains electrical panel with a Whole House Surge Suppressor. Many of these devices have clamping voltages that start at 600+ Volts or more so some external surges still make their way into the home & many in-house generated surges are too far away from the panel so surge protection in the house is still needed.

Coax connections (CATV, Internet, Satellite, &/or antennas) are best dealt with where they enter the house. An effective method is to run the coax cable into a ground block then into a hybrid surge arrestor that uses a combination of GDT/MOV technology such as the Morgan Mfg M311. The GDT will ignite, glow like a NEON light & the MOV will direct the surge on the central conductor of the coax to ground quickly. Both the ground block and the surge arrestor need a short low impedance path to earth ground.

TELCO connections if still used can be protected with a commercial device like the Eaton CHSPTEL. Protection at the service entrance eliminates the need to provide additional protection throughout the house for coax and TELCO.

Ideally if you could put a buried ground rod at each point of surge protector in the house, you could provide a low impedance path to ground, but all the ground rods would have to be connected together and this is not ideal or practical. Plus the MOV is voltage based & damaging currents can still get passed it before the MOV starts to work and while it's working.

One could invest in point isolation transformers (better than MOV technology) similar to those used in high end audio equipment but this would be a very costly.

Another technology called series-mode is basically a heavy duty low pass filter filtering anything faster than 60 Hz including spikes, transients & surges. The surge energy is slowed down in real-time, stored as energy in capacitor banks and then safely bled onto the neutral a few volts at a time. Recall the water analogy, slowing the surge down is the key otherwise the impedance of the return path might be too high & the surge will seek another way. Series mode offers true surge elimination, lowest VPR, highest MCOV.

Series mode filters can cost more initially, starting at $139 for a new 2-outlet 7.5 amp model from Zero Surge, Inc. and $159 for a new 2-outlet 15 amp model from the same company. These can also be purchased used or new old stock on the popular auction site for as little as $30 to $75+. Since no MOV’s are used, they aren’t sacrificial & will last a lifetime in the intended application.

Consider the annual replacement of an MOV based surge protector like this one that costs $12, over a 15 year period you’ll have spent $180+. Contrast that to a new $170 2-outlet 15 amp model or $60 for a new old stock 2-outlet 7.5 amp model & long term economics favors series mode on price alone. Factor in true surge elimination vs. surge diversion/hope for the best then series-mode wins hands down.

Series mode filters are available from Zero Surge, Inc. (inventors & holders of the patents), Brickwall (a private label of Zero Surge aimed at audiophiles) & SurgeX (a licensee of the technology). You can purchase Zero Surge and Brickwall directly from the manufacture and SurgeX here on NEWEGG. All 3 can be purchased on the popular auction site.

You can’t daisy chain MOV based surge protectors for safety reasons, but you can safely plug an MOV based surge protector like this one into a series mode filter to expand the number of outlets. If you have a UPS, you can also safely plug a UPS into a series mode filter and since many UPS’s have MOV surge protection built in, a series mode filter will ensure that the MOV protection never wears out.

Rating + 5Rating + 5Rating + 5Rating + 5Rating + 5 PERFECT!
Pros: If I needed another power strip with TEN . . . (not eight) well spaced sockets, four of them able to accommodate non-standard and weird shaped bricks, all with a more than adequate joules rating, and complete with dust covers for unused sockets, it'd be a no-brainer. I'd just order another one of these.
Cons: Have yet to find one.

Categories > Surge Protectors > SURGEX > SurgeX MFP-1 Surge Suppressor

Rating + 5Rating + 5Rating + 5Rating + 5Rating + 5 Excellent value for what you get
Pros: Cheapest, new, non-MOV based surge protector I was able to find thus far. SurgeX uses series mode and advanced series mode protection in their product line, rather than MOV;s. This is technically a surge-eliminator if what I read at their site is true. Though, again, of their many products, this is one of their least expensive. One outlet, along with cat-5 ethernet, and fax/modem/dsl i/o's. All of the models I looked at tended to offer exceptional noise filtration as well. While I forget what the specs were for this one, I think it was rated at over 40 db. I figured this made an excellent choice for a unit to plug my desktop's psu into.
Cons: none I know of
Other Thoughts: If I ever get a USP someday, I guess this will be what I plug it into.

Categories > Surge Protectors > APC > APC P11VT3 8 ft. 11 Outlets 3020 Joules Performance SurgeArrest 11 Outlets with tel2/splitter and coax jacks

Rating + 5Rating + 5Rating + 5Rating + 5Rating + 5 Highly rated MOV-based surge protector
Pros: Good value for this model. According to research mentioned in The Wirecutter (Dec 2015) this protector clamped a 600-volt spike down to 160 volts, while most of the other models tested only managed to get the spike down to between 250 and 400 volts. It's noise filtration reduced radio-frequency noise at the AC outlets by an average of -30.4 dB, which is above-average performance among the units tested, as well. It was these findings that led me to choose this APC model.
Cons: None so far.
Other Thoughts: Not a surge eliminator that uses series mode, or advanced series mode protection, But for an MOV based surge protector, it's one of the better to best models in this category.

Rating + 5Rating + 5Rating + 5Rating + 5Rating + 5 Works as intended
Pros: Has 10 outlets, a 6-foot connection cable, 4 widely spaced outlets for those ugly power warts, EMI / RFI filtration and noise reduction, its a 2850 joule surge suppressor and sliding covers for thos outlets not in use.
Cons: None
Other Thoughts: The CyberPower B1006T Surge Suppressor RJ-11 Phone Protection, though I don't have a use for this portion of it, was the perfect outlet for my needs.

I give it 5 stars because it works as fine as a power strip and has a some nice features, but really hope I never have to test its surge supression capability, or that of any other strip.
