Find a number of questions that we often hear at DITEK, along with their answers. These questions cover a wide range of surge protection-related topics. If you think a new question should be added here, please let us know!
NRTL certifications may not always be required; however, the primary purpose of surge protection devices is to protect your staff, equipment and facility from damaging power surges. Because of the critical nature of this goal, it only makes sense to choose products that have been designed and tested to the highest national standards. Learn more by reading our whitepaper.
Yes. A low impedance ground is imperative to both surge protection designs and power quality. An SPD is a passive device until there is a change in voltage (overvoltage). Then the SPD turns on and shorts the energy to ground and away from the protected circuit. When the fault has cleared, the SPD resets and is ready for the next event. Learn more about the importance of grounding in our Bulletin.
Power surges are impossible to predict or prevent, and can cause massive damage to any device on your power grid or IP network. The best way to reduce your risk of damage and destruction caused by a power surge is to take proactive measures to protect your critical business equipment. Read more about how being proactive when installing surge protection can help keep your business running in our whitepaper.
According to the Insurance Institute of Business and Home Safety, lightning strikes account for just two percent of all surge-related damage. That means 98 percent of the damage is caused by the hundreds of smaller power surges that typically go unnoticed every day. Learn more about power quality in our Bulletin.
Surge protective devices (SPDs) deliver a critical defensive function for electronic equipment and systems used to run businesses by ensuring that power surges do not damage or destroy them. An SPD may survive to protect your business for years – or only for a few days – depending on its exposure to surges. Knowing when to replace it means reading our blog.
Surges come from utility supplied power, human error, mechanical equipment or natural and atmospheric events. A common misconception about power surges is that devices are only at risk during extreme weather, but power surges can happen at any time without warning. Learn more about where power surges come from and how to protect your electronics from them in our whitepaper.
It is “best practice” to protect both ends of a cable or wire run because when overvoltage surge energy is applied to any metallic conductor it will travel in both directions trying to find the least resistive path to ground. This is usually right through your equipment.
No, DITEK Ethernet and PoE surge protectors use state-of-the-art circuitry to provide the highest level of protection in the industry, and are compatible with network speeds up to 10GbE without signal degradation. Learn more about all of our 10GbE Surge Protectors.
We recommend protecting loop circuit wires before they terminate at the Fire Alarm Control Panel. If the conductors are protected when they first enter the building, there is a risk of surge damage after the surge protective device.
Wireless communicators require an antenna kit to attain an acceptable signal strength. Since antennas are external to the building, they become an avenue for damaging transient surges to enter your system through the coaxial antenna cable. Learn more.
Uses an inverter in line and redirects the battery’s DC current path from charging mode to supplying current when there is a loss of power. This is done with the use of an AVR (Automatic Voltage Regulation).
