Radio Frequency and Facility Power Line Filter Selection Made Easy!

ETS-Lindgren's New Brochure Addresses EMP and EMC Filter Applications


CEDAR PARK, Texas, October 22, 2020 ETS-Lindgren is proud of its decades of experience in the design, manufacture, and installation of Radio Frequency (RF) Shielded Enclosures.  With over 25,000 RF Shielded Enclosure installations worldwide, there is one common, often overlooked product that is key to the success of every installation.  Can you guess the product  A hint is that it involves a Point of Entry (POE).   "People underestimate the importance of protecting all points of entry in an RF Shielded Enclosure, especially for power, signal, data, and control lines," said Sergio Longoria, ETS-Lindgren's Technical Product Line Manager for Filters.  "While the cost of filters is often a minor part of an overall project, filters play a key role in the overall success of every project.  A poorly designed or mismatched filter for an application, for example, can compromise the RF shielding integrity of the facility thereby eliminating the protection of the secure environment. In other cases, the safety of personnel and equipment may be jeopardized." 


To assist RF Shielded Enclosure users with their RF and Facility Filter requirements, ETS-Lindgren's veteran engineering team created the brochure "Top 10 Considerations for RF and Facility Power Line Filters."  The new brochure addresses the most important considerations when selecting power line filters for protection of POE against adverse effects, such as electromagnetic interference (EMI) or electromagnetic pulse (EMP).  Guidelines are provided for unique applications, such as use of 400 Hz filters, installation of EMP filters on secure shelters, and filters placed in parallel to achieve high current ratings.  You'll find ETS-Lindgren's expertise evident in this quick and concise guide created to ensure the success of your next project. 


"As RF Shielded Enclosures have become increasingly complicated with recent requirements involving shielding protection of mobile shelters, computer racks, power transformers, and critical infrastructure, power line filters have become increasingly sophisticated," said Joel Kellogg, Director of Business Development for Healthcare, Industry, and Government with ETS-Lindgren.  "We're seeing an increase in custom filter designs and demand for EMP filters as a result of these specialty RF Shielded Enclosures.  We included content on EMP filters in our brochure as many applications for these filters have zero tolerance for failure in the field.  In fact, since this application in particular is part of increasing pressure from the US Department of Energy and the US Department of Homeland Security to protect critical infrastructure, we created a series of webinars with industry experts to address the need for education on protection from EMP threats."


The first webinar in this EMP series was held on October 14 with speakers Mr. Longoria and noted consultant Dr. D. V. Giri.  Professor Farhad Rachidi with the Swiss Federal Institute of Technology (EPFL) moderated the session.  You can listen to the recording of this webinar that addressed "Protecting Power, Signal, and Data Lines from Adverse EMI/EMP Effects" here.  The second webinar will be held on November 11 with Mr. Kellogg and Dr. Eric Easton of CenterPoint Energy.  The topic addresses "EMP/IEMI Governance and Mitigation Strategies."  The moderator is Professor Edl Schamiloglu with the University of New Mexico and President of the Summa Foundation Board of Directors.  Registration and more information is available here.  A third and final EMP webinar for 2020 is planned for mid-December.  Details will be announced shortly.


After decades of experience in the design and manufacture of standard and custom power, signal, data, and control line filters, ETS-Lindgren is pleased to share this expertise in the new Top 10 brochure as well as in webinars with industry leaders.  And while ETS-Lindgren can boast of over 25,000 installations worldwide, it is important to note that ETS-Lindgren's engineering, R&D, and manufacturing team for RF and Facility Filters is solely located at the company headquarters in Cedar Park, Texas.  With over 700 employees, manufacturing facilities, and offices in Europe, Asia, and the US, customers benefit regionally from the global resources available from ETS-Lindgren's headquarters in Texas.
