GIA has released a comprehensive global report on Surge Protection Devices (SPDs). The global market for Surge Protection Devices (SPDs) is forecast to reach US$2.4 billion by 2020, driven by the growing need to protect sensitive electronic equipment from power fluctuations.

Surge protection devices such as transient voltage surge suppressors and surge arrestors are growing in importance, given the billions of dollars of losses caused by voltage fluctuations and power line abnormalities. Widespread use of sophisticated electrical, electronic communication and data equipment is driving the importance of power management solutions including SPDs, in both developed and developing economies. Proliferation of home appliances, personal computers, heating and air conditioning equipment in residential homes, and installation of high-end industrial electronic equipment in manufacturing plants are driving growth in the market. Future growth in the market will continue to benefit from the increasing use of electronics in the rapidly growing world telecommunication industry.

The commercial end-use sector is expected to witness strong growth in the coming years. With nationwide alternate energy programs gaining popularity in Germany, China and other major economies, demand for surge protectors is expected to gain strength. Substitution of conventional coil and core street lamps with light emitting diodes for outdoor lighting is also opening up new growth avenues for SPD manufacturers. Miniaturization and clock speeds of microprocessors as dictated by Moore’s Law comes at a price, namely higher sensitivity of the chips to power transients, electromagnetic interference, radio frequency interference and electrical field transients. The increasing sensitivity of modern electronic devices to even split-second electricity fluctuations bodes well for sales of SPDs. The global market for SPDs is extremely competitive characterized by a high degree of fragmentation, and pricing pressures. The relatively commoditized SPD technology leaves very little scope for differentiation. Pure-play SPD manufacturers face stiff competition from large diversified electrical equipment makers.

As stated by the new market research report on Surge Protection Devices (SPDs), the United States represents the largest market worldwide. Developing countries are forecast to spearhead future growth in the market led by mounting issues related to stable power supply. Escalating demand for energy as a result of robust pace of economic development and industrialization, inefficient energy infrastructure and power shortages, are key reasons responsible for poor power quality in these countries. Asia-Pacific, led by China and India, is forecast to witness the strongest growth over the analysis period. Key factors driving growth in the region include the growing consumer appetite for expensive electronic devices, and migration of industries towards digitization and automation of production and business processes.

9 things you should know about surge protectors

9 things you should know about surge protectors

Surge protectors are an inexpensive way to protect your gear against random power spike damage. They're not all the same. Here are a few tips before you start shopping.

Whether you're just looking to add more outlets, or want to add a layer of protection between your gear and the outside world, you'll eventually want to buy a surge protector.

With an incredible range of prices and features, not to mention a barrage of questionable marketing promises, it's hard to figure out what's worth the money, and what's nonsense.

To help you sort through it all, here are nine things you should know about surge protectors.

For a little background, check out what makes a good surge protector. This article is the spiritual successor to that piece, though we'll cover some similar ground.

1. Not all are the same.

Power strips and surge protectors (also called surge suppressors) are different. Typically, power strips are cheap, multi-outlet products that are merely an expansion of a wall outlet. These usually have a circuit breaker of some sort, but most don't offer any real "protection" from electrical issues. Some might have the barest level of protection, but they're all pretty much just like plugging into the wall direct.

Surge protectors offer some level of protection against power spikes. How much and how well varies considerably.

2. It's all about the joules.

Surge protectors offer protection in amounts called joules. Think of this like a reservoir of protection. If a product has 1,000 joules of protection, that means it can take ten 100 joule hits, or one 1,000 joule hit. Generally, the more joules the better.

How do you know how many joules a protectors has left, or if the rating is even accurate? Well, you don't. The Wirecutter did a massive test on surge protectors, essentially blowing them up to see how well they worked, to see if they could answer this question.

3. A warranty...on your stuff.

Some surge protectors offer a warranty (up to a certain amount) on the gear connected to the protector. For example, in the US, one Belkin model has a $300,000 Connected Equipment Warranty, and states: "If your electronic equipment is damaged by a surge, spike, or lightning strike while properly connected to this power strip, we will repair or replace it, up to $300,000."

You'll probably never need it, but it certainly doesn't hurt to have it. Belkin has similar warranties in effect for other products, but they vary by region.

Edit 7/31: As some readers mention in the comments below, just because the warranty exists, doesn't mean you'll ever see a dime from it. A good point.

4. A power "conditioner."

There are a number of products on the market that claim to "condition" the power from the wall, promising improved performance in your gear. Here's the dirty little secret: your gear already does this. All electronics have a power supply that takes the incoming wall current (110v in the US), filters it for noise, and converts it into whatever the device needs. Almost nothing actually runs on 110 volts (or alternating current, for that matter), so unless you've got some really wacky (or cheap) gear, and live in an area with bizarrely inadequate power, a power conditioner isn't something you need.

5. Always get more outlets than you need.

You're always going to need more outlets. You'll undoubtedly add more gear, without necessarily getting rid of your current gear. I'm not saying that if you think you need 4 outlets get a 12, but a 6 is probably a good investment.

6. Power spikes can come over any wire.

If you want total protection, consider that phone and cable lines can carry power spikes too. Some surge protectors have connectors for these as well.

7. USB is great, but check the amps.

Many surge protectors come with USB connections, so you can charge your mobile devices. Handy, for sure, but check what the output amp rating is. Generally, this is either 1 or 2 amps (often labeled 1A or 2A). This is how much flow you can get through the pipe, so to speak. For a mobile phone, 1 amp is enough, but for a tablet, you'll want 2 amps for quicker charging.

8. Get a portable power strip.

While not offering much protection, a portable power strip might prevent marital friction, and/or invoke bliss from travel companions. Most hotels and hostels have few accessible outlets, yet everyone has multiple devices that need recharging. Most portable power strips add two to three additional outlets, plus offer direct USB charging (see number 7!).

9. They don't last forever.

Remember the joule rating we discussed earlier? Well, it means that over time, a surge protector is going to wear out. Some will give you a warning when they do. Many won't. If you know you've had a serious electrical event (like lighting blew out a transformer down the street), it's probably worth replacing your surge protector just in case.
Bottom Line

There really is no reason not to get a surge protector. How much you need it will vary. If you live in an area with lots of thunderstorms, your gear is probably more likely to experience power surges. Even if you live in the desert, your A/C or refrigerator could kick power spikes back down the lines to your A/V gear.

Since most surge protectors are cheap, they're worth getting just in case.

Uninterruptible Power Supplies and Your Data Center

uninterruptible power lights

What exactly is an uninterrupted power supply? How do you know which UPS is right for your data center? These two questions prove to be pivotal when setting up a data center or a data room that will service the needs of your organization. When you use technology, the most important part of the equation is power. With out power or a steady stream of power, it can be impossible to deliver services reliably through out your organization.


Even computer hobbyists could gain from using a UPS in their environment. Servers, computers and most other electronic equipment thrive off an uninterrupted power source. Data centers are the number one customers for UPS devices. Why? Electricity delivered from utility companies doesn’t remain constant. A slight power surge, power sag or outage could be detrimental to your organization’s objectives.


Infrastructure equipment works best when it gets a steady, regulated source of power. This helps ensure the longevity of the equipment you are using within your data center. When devices such as SANs or other types of storage appliances receive inconsistent power, you are directly putting the integrity of your organizations data at risk. Having a UPS within your onsite data center is easily one of the first things a data center architect should look at implementing within the facility.


How can you determine the best UPS for your needs?


You must first determine what you actually have. UPS devices come in large, small and modular designs that will fit inside of racks or as a standalone appliance within a data center. You should research the specifications of the specific UPS device you are interested in purchasing so that you can gather enough information which will enable you to make an educated decision.


Another factor you should consider is whether or not your site has a generator that could kick in during an outage. Most UPS devices use lead batteries to keep devices running during a power outage. If you do not have a generator onsite, you may want a more robust UPS solution. If you have a generator on site and you know that the generator will repower your facility within 60 seconds, having a super robust UPS could be overkill.


Uninterrupted Power Supplies sometimes comes with a flywheel design versus the traditional lead battery model. There are pros and cons and many organizations only utilize the flywheel design based on space constraints or green energy endeavors. The flywheel spins and when power loss is detected, the energy generated from the wheels motion is used by the data center’s equipment. The fly wheel slows down thus indicating that the perpetual motion that keeps the flywheel moving is waning. The flywheel design is gaining more popularity because it leaves a much smaller environmental impact than the traditional UPS systems, especially within green data centers of the future.
