Why Your Should get PoE and Surge Protection form a Single Source

Single Source SupplierPower over Ethernet (PoE) is a revolutionary technology powering critical technology that keeps people and buildings safe. Over the last few years, PoE has become the go-to-choice for a host of networked devices, including IP security cameras, IP phones, and wireless access points. What makes it so popular is its ability to provide both data and DC power to devices through a single Ethernet cable.
The "plug-and-play" nature of PoE makes installation of remote equipment easy because it does not require any additional power cabling. This enables installers to place equipment in remote locations, away from any service panel or other power source.

Power surges can harm PoE systems

However, PoE devices are just as vulnerable to the effects of power surges as any other type of electrical equipment. With PoE so commonplace, plenty of vendors can provide equipment necessary to install PoE-based networks. However, how many of them are experts in surge protection? Here's why that's important.

While it's common knowledge that lighting strikes can cause a momentary—but dangerous— surge in voltage, weather is only responsible for a small percentage of actual surge events. Most are the result of technology, including fluctuations in local electrical grids or powerful motors found in HVAC equipment or heavy machinery cycling on or off inside a building.

Why The Electric Vehicle (EV) Infrastructure Needs Surge Protection

2021 09 EV Charging Stations 320Getting more people into electric vehicles is a major component of the Biden administration's plan to reduce greenhouse gas emissions. According the US Department of Energy, the U.S. has over 44,000 public charging stations for battery electric vehicles (BEVs) and plug-in hybrid vehicles (PHEVs), with over 180,000 charging ports. 1However, the government's $2 trillion infrastructure bill calls for a whopping 500,000 electric vehicle (EV) charging stations by 2030.

That's an ambitious goal, given that over 30 percent of charging stations reside in one state—California, which leads the nation in EV sales. Other states with strong EV sales include Florida, Texas, and Washington.2

Big hopes for EV boom
While the EV revolution has been slow to arrive in other parts of the nation, experts predict a rapid increase in BEVs and PHEVs sales as prices gradually fall and major manufacturers, including Ford and General Motors, ramp up production to catch industry leader Tesla. In 2020, BEVs and PHEVs represented slightly more than 2% of vehicle sales in the United States, totaling just over 295,000 vehicles. 3In order for EV adoption to occur at desired levels, the EV charging infrastructure must expand—and fast.

DITEK - A Legacy of Family, Philanthropy and Industry-Leading Products

Team DITEKDuring the thirty years I led DITEK as founder and CEO, three guiding principles defined our company. First, treat each employee with respect. Second, only build the highest quality products. And third, never stop giving to your local community.

In addition to building a successful business our employees love, we’ve had the privilege of working with extraordinary charities in the Tampa Bay area. We've helped build schools, fund scholarships, and protect the families of first responders.

And to think, it all started at a Super Bowl party over forty years ago.

Chance meeting

Long before DITEK was founded, I was in my late twenties traveling around the United States in the sporting goods industry. At a Super Bowl party in the late 1970s, I met an entrepreneur who was making surge protectors in his garage. The technology wasn't as sophisticated as what we make today, of course, but I was intrigued. He understood manufacturing and I knew sales, so it was a natural connection. We worked together to turn his garage operation into a nice business.

How to Calculate ROI for Surge Protection

2021 06 ROI 320The topic of electricity reliability and resiliency has emerged as a top-of-mind concern for many systems integrators and their end-user clients. While utilities, regulators, and policymakers struggle to protect the national grid, the average facility is more concerned about how to achieve optimal levels of electrical reliability and reduce future disruptions in power.

The reality is that the cost of power disruptions for most organizations continues to rise. In 2006, Lawrence Berkeley National Laboratory developed an end-user based framework that estimates the cost of power interruptions in the U.S. The last study released in 2018 shows that the total U.S. cost of sustained power interruptions is $44 billion per year (2015), which was 25% more than the $26 billion per year in 2002. The majority of the costs (70%) were suffered by commercial sector customers. The industrial sector accounted for 27% of the total cost.

Protect PoE Devices from Power Surges and Other Disruptions

Outdoor PoE CamerasFirst introduced in 2003, Power over Ethernet (PoE) has made installing equipment in remote locations convenient and affordable. One single Ethernet cable can deliver both DC power and data to low power PoE-enabled equipment, including IP security cameras, network access points and switches, and building access controls.

PoE was originally developed for IP phone systems and delivered only 7W of power. Over time, the technology has improved and can now accommodate up to 90 watts / 57 volts. PoE eliminates the need for additional (and more dangerous) A/C power wire runs to end-point devices.

Outdoor PoE devices are exposed to weather-related surges

While most Ethernet cable is relegated for indoor use, more and more outdoor systems are utilizing PoE due to its ease of installation and operation. The downside is this exposes PoE devices to the risk of power surges or spikes caused by weather conditions, including lightning strikes and other disruptions.

Like any electronic system, PoE devices and their internal components operate within specific current and voltage ratings. Excess current or voltage can damage delicate internal components.

Best Practices for Surge Protection

Best Practices for Surge ProtectionBest practices are important for processes that you need to work correctly. When it comes to the world of electrical and low-voltage contractors, best practices ensure that maximum efforts are taken to create a safe environment, which can mean the difference between life and death in some cases.

Most accidents involving electricity are the result of unsafe and improper work practices or improper installation and equipment. Best practices when installing surge protection may not be as simple as grounding, guarding, and insulation. When planning a surge protection strategy, the best place to begin is by assessing the incoming power connections. This is the primary entry point for power surges and spikes that originate from outside the building. Protecting the power connection also provides protection from internally generated power anomalies resulting from refrigeration equipment, air handling equipment and similar high current devices.  Be sure to consider any additional systems your facility might have including data, fire, security and communications.

Electrical Product Safety Testing: A Mutual Trust

Electrical Product TestingElectrical product safety is one workplace compliance standard any organization, systems integrator or project manager takes seriously. Research statistics we see from IEEE and NFPA demonstrate just how dangerous electricity can be if work safety and health concerns are not enforced. The business impact resulting from careless electrical accident prevention ultimately causes downtime and costs both lives and revenue.

To help organizations understand and have the capacity to implement their own electrical safety protocols, The United States Occupational Safety and Health Administration (OSHA) requires that 38 different types of products, devices, assemblies, or systems used in the workplace be tested and certified by third-party organizations identified as Nationally Recognized Testing Laboratories (NRTLs). Since its establishment in 1970, OSHA’s goal has been to create safe workplaces.

Fire Protection and Prevention Innovations

Fire Alarm PanelFire safety technology has certainly evolved over the last 125 years since the first automatic fire alarm system was patented and the National Fire Protection Association (NFPA) was launched. While innovation in the fire industry can be slow and sometimes plodding, it seems that external forces more than technology advancement has driven the development of new solutions and products. With the spiderweb of varying state fire codes and regulations, evolving infrastructures and construction mandates featuring a growing emphasis on LEED compliant and green building certification programs, innovative fire protection technology has had to adapt to the growing complexities of the world.

Innovative Smart Technologies Emerge

As “smart” technologies expand across the Internet of Things (IoT) landscape, advanced smart devices are transforming the way security and fire safety professionals approach building design and fire suppression and prevention methods.

What Causes Lightning: Distinguishing Facts from Myths

Lighting StikesThe properties and effects that characterize a lightning strike are truly remarkable. Lightning begins as a high-intensity electric impulse that initially grows in a gaseous environment while forming in the atmosphere and then evolves into a solid, more or less conductive medium when it strikes the ground. However, the fireworks that take place during this celestial trip from heaven to earth can be simultaneously wonderous and devastating. The visual effects of the lightning flash followed by the shockwave of thunder and the sheer thermal dynamics of the heat generated by the event also create residual electrodynamic and electrochemical side-effects that can disrupt power, create electrical surges in office and industrial devices and interrupt network communications.

A lightning strike is perhaps one of the most feared and yet wonderous natural occurrences. When you figure that a person’s odds of being struck by a lightning bolt are a minuscule one in 12,000, yet astraphobia is the third most common phobia in America, behind acrophobia (fear of heights) and zoophobia (fear of animals), it proves most people respect its savage potential. However, climate scientists are wary that with the earths rapid weather changes, the chances of being a lightning-strike victim could increase to one in 8,000 by the year 2100.
