Lightning arrester "Dane Guard TTH"
This is a surge protective device (SPD) for power circuits (arrester/lightning protector). 【Features】 ○ Equipped with SPD deterioration detection function. It can be identified by the display on the front window. (Green: Normal, Yellow: Deterioration, Red: Failure). ○ Even in the yellow display (deterioration state), the lightning protection performance is maintained, allowing for replacement before failure without interrupting protection. ○ Built-in alarm output C contact. ● For other functions and details, please contact us.
Surge arrester "DEHNpatch"
This is a lightning protector for LAN use. 【Features】 ○ It supports 1000BASE-T, which could not be accommodated before due to high transmission speeds. It also supports Power over Ethernet. ○ The RJ45 male connector type comes with a CAT.6 cable, making it easy to connect to LAN boards and hubs. ○ The RJ45 female connector type is lightweight and space-saving, offering high versatility for installation locations. ● For other functions and details, please contact us.
Lightning arrester "DEHNgate"
This is an SPD for TV use. 【Features】 ○ SPD for coaxial cables compatible with video antennas (F connector connection). Compatible coaxial cables have a center conductor diameter of φ0.75 to 1.13. ○ Supports DIN rail installation method for easy installation within panels (excluding DEHNgateGFTV). ○ Wide frequency range of 5 to 3000 MHz, suitable for VHF, UHF, and satellite broadcasting. ● For other functions and details, please contact us.
Surge arrester "DEHNblocMaxi"
This is a surge protective device (SPD) for power circuits (arrester/lightning protector). 【Features】 ○ Class I SPD compatible with 400V circuits ○ The status of the SPD can be checked via the display on the front window. Additionally, the status of the N-PE gap can also be indicated. (Green: Normal, Red: Fault) ○ Built-in output contacts for fault conditions, eliminating the need for complicated wiring. ● For other functions and details, please contact us.
In the summer of 2022, lightning struck a utility pole on the premises. When holding an outdoor performance, "lightning can't be helped" is not an acceptable excuse.
We would like to introduce a case where "PDCE lightning protection balls" were installed as a lightning strike countermeasure for an outdoor ballet performance. A few years ago, on a day off, lightning struck a steel tower at the ballet venue, causing damage to the sound and lighting systems. For the 2024 performance, we will install a total of three of these products on the lighting towers and stage, and we have asked a local contractor who has long been involved in stage setup to handle the installation. This product, equipped with features that prevent lightning strikes, has already protected 4,400 units nationwide, including those for the Self-Defense Forces, railways, factories, and outdoor sports facilities. 【Case Overview】 ■ Issue - On July 27, 2022, lightning struck a utility pole at a hotel, damaging all electrical systems and rendering refrigerators, air conditioners, well water pumps, and boilers unusable. ■ Response - Installed a total of three PDCE lightning protection balls on the lighting towers and stage. *For more details, please download the PDF or feel free to contact us.
![[Case Study] Automotive-related Factory (Protection of Firefighting Equipment)](https://image.www.ipros.com/public/product/image/214/2000447941/IPROS19169110178443986803.png?w=280&h=280)
Are you fully prepared for lightning protection? Here are some examples of implementation in actual automotive-related factories!
We would like to introduce a case study for the protection of fire-fighting equipment requested by an automotive-related factory. After the implementation, the person in charge stated, "Repeated lightning strikes have been disrupting our operations. I was concerned about how much we could prevent, so we decided to install a lightning arrester on the equipment that had suffered the most damage and set up a counter. We were then able to monitor the lightning situation with the counter, and we are currently considering our next lightning protection measures." 【Case Study】 ■ Client: Automotive-related factory ■ Purpose: Protection of fire-fighting equipment ■ Feedback from the person in charge: - Repeated lightning strikes had been disrupting operations - We installed a lightning arrester on the equipment that had suffered the most damage as a trial - We were able to monitor the lightning situation, so we are currently considering our next lightning protection measures *For more details, please refer to the PDF document or feel free to contact us.
