Why SEL?
SEL devices are installed throughout the global electric grid and many other industries that demand continuous availability, like petroleum refineries and water and wastewater systems. Whenever a first responder trusts electric power to reliably charge their handheld radio, they’re probably already being served by SEL technology.
Just like the other critical systems we protect, emergency services need equipment they can trust. Our solutions operate dependably without human intervention for years, enduring temperatures from –40° to +85°C (–40° to +185°F).
Our LMR solution is interoperable with major radio vendors, and because we perform our own manufacturing, we can offer lead times of ten days or less for most products. And with our ten-year warranty, no-cost repair service, and complimentary around-the-clock support based in the United States, radio managers can always reach an SEL engineer for help.

End-to-End LMR System Support
Precise Timing
The SEL-2488 Satellite-Synchronized Network Clock reliably synchronizes each repeater site in the LMR network and equipment in public safety answering points (PSAPs).
Resilient and Cybersafe IP Networks
The SEL-2731 and SEL 2742 Ethernet Switches create secure and resilient LANs with operational technology (OT) software-defined networking (SDN).
Flexible Networking
The SEL ICON Integrated Communications Optical Network provides flexible voice transport services and wide-area networking.
Remote Monitoring
An SEL Real-Time Automation Controller (RTAC), like the SEL-3350 RTAC and SEL-2240 Axion, allows you to remotely monitor the entire system from one interface.
Rugged Computing
Rugged computers like the SEL-3355 protect the operation of critical software at remote sites without climate control.
