UL 1449 is the Underwriters Laboratories Safety Standard for Surge Protective Devices (SPD). Surges are rapid increases in voltage and current that can occur on AC or DC power circuits that can damage equipment attached to these circuits. An example of a surge would be a lightning strike on or near exposed power lines. The strike can induce voltages on the power line that can exceed a million volt.... Read more

Global positioning systems are an important part of any RF network. GPS provides timing information that is critical in keeping RF networks synchronized. It is important that GPS receivers be protected from lightning strikes with RF lightning arrestors.... Read more

Today’s industrial applications include a broad range of sensitive, valuable and critical electronic equipment, from automation and control systems to instrumentation and LED lighting. Protecting this equipment from surges, transients and other power anomalies is critical to maintaining performance and minimizing revenue loss from downtime. Transtector Systems and PolyPhaser provide a broad range of surge protection solutions for industrial applications. What strategies are best for this application?... Read more

One of the main issues confronting a small cell deployment is getting permits for the build and having them approved once the build is completed. Once a site has been identified, the permitting process begins. One of the main hurdles for approval of a permit is approval of the BOM that will be used at a small cell site. Electrical safety is a major concern of municipalities. Having a cabinet that is UL 67 Listed will address these safety concerns. This will facilitate in the approval of site permits as well as having them signed off during final site inspection.... Read more
