Note: Our SPD manufacturer (SSI) provides surge protector comparison testing via surge generator and industry standard surge test protocols to substantiate SPD performance. SSI has tested numerous competing SPDs at their CSA ANSI/UL 1449-2006 certified testing facility in Brooksville, FL as well as testing for attendees during IEEE accredited Continuing Education Courses/Seminars.
Course materials include SPD designs,
protection modalities, surge environments, terminology and related
subject matter. The course is open to engineers, building
managers, executives, electricians, maintenance managers and the
like. If interested in attending (or viewing online) a Transient Voltage/SPD seminar to learn more or to earn CEUs/PDHs click here. For examples of tested SPDs, click below.
Surge protector comparisons can be difficult, especially if discussing product literature or marketing claims vs real world application results. Product specification sheets are helpful if familiar with the product nomenclature. However, most readily available data is called "marketing material" for a reason.
Generally, SPD performance claims via marketing materials are difficult to validate without testing equipment to verify them. After all, performance is usually why one
product is purchased over another isn't it? Furthermore, one usually expects the product to perform as advertised.
Why choose High Quality, High Performance SPDs over General Marketplace SPDs?
High Quality, High performance SPDs offer:
These compact sized, solid-state constructed SPDs deliver:
High Quality, High Performance surge protectors deliver superior protection. These devices outperform the average commodity driven SPDs flooding today’s market place. To help support this position, the effectiveness of different SPD designs were observed in a simple comparison test.
It doesn't matter if the SPD is a Type 1 or 2 panel application for industry, business, residential or the everyday direct connect plug-in surge protector.
Circuitry design, type of components and quality of components in SPDs are important. Many times, a number of these components may be similar. However, combining components, number of components and design methodology are typically quality and performance separation points.
Below is an example of three different outlet surge
protectors that were used to protect the power side of a home office network. All three units use similar concepts and share some similar
components to achieve protection.
This surge protector comparison demonstrates differences in SPD designs, SPD marketing claims and SPD performance. We didn't have a surge generator, so we applied a simple, straightforward method...
...Real World Application.
This comparison is termed in-use or Real World. Its
the result of three different SPDs put to use over a 5 year time span.
The units in this surge protector comparison make similar protection claims. However, the claims and results were not similar during the time period. In two of the three cases a "protected" piece of equipment was damaged and failed.
All three Units Include:
Basic Unit Marketing:
Units Marketed For Electronics Protection:
Effective and dependable surge protection is available in the marketplace. The trick however, is determining what effective and dependable actually means, comparatively speaking.
Types of components, quality and quantity of components and device design determine effectiveness. Again, this is true for Panel connected SPDs (Type 1-2), Data, Telecom and plug-in units (Type 3).
All surge protectors are not created equal. Although at times, marketing material and performance claims seem to take you in that direction. Some product marketing materials are accurate and others not so accurate. How the SPD functions in Real World Applications is what counts.
Remember: all three plug-in devices were marketed as providing Electronics Protection.
