Government Solutions and Services

SEL practices secure supply chain management and helps our customers and partners comply with all applicable supply chain and cybersecurity standards. This includes meeting DFAR supply chain security and risk management clauses.

Our manufacturing, research, and business facilities are protected by layered cybersecurity defenses and stringent physical security measures. The information security, quality, safety, and environmental management systems that underpin SEL research, development, manufacturing, and corporate environments are each certified to internationally recognized standards by the British Standards Institution (BSI). 

SEL electronic devices are made in America, in facilities we own and operate. Printed circuit boards (PCBs) are sourced exclusively from American manufacturers (and will soon be manufactured in our own plant).

We thoroughly review and test the code that goes into our products. Source code is continually monitored for new threats. We notify our customers of updates and security patches for the full life of the product. Software and firmware updates are distributed directly to our customers via secure file transfer, and their authenticity and integrity are verifiable through digital signatures and cryptographic hashes.

Research and Development Services

SEL Government Services partners with U.S. government agencies and national laboratories to perform mission-driven research and solution development for electrical system design, protection, and control.

We direct the applied research, product development, and compliance testing capabilities of SEL toward your objectives, ensuring that your research investment yields the highest possible return.

Our specialized testing and research facilities are protected by layered cybersecurity defenses and stringent physical security measures, and are dedicated specifically to the needs of U.S. government agencies and their contracted system integrators.

Integrator Services and Procurement

From proposals through procurement, SEL Government Services works with you to deliver equipment and solutions that meet your customer’s specifications.

We test, modify, and harden our already reliable commercial products to meet MIL-SPEC and custom requirements—and we stand by our equipment with lifetime support and the industry’s best warranty.

Lifetime Product Support

Technical support is available for the entire life of every SEL product.

We also train both engineers and on-ship personnel in maintaining and operating our protection and control systems.

Security Bulletins and Updates

We notify our customers of updates and security patches for the full life of the product. Software and firmware updates are distributed directly to our customers via secure file transfer, and their authenticity and integrity are verifiable through digital signatures and cryptographic hashes. 

SEL Process for Disclosing Security Vulnerabilities 

Proven Reliability

SEL electronic devices are designed for a working life of at least 20 years.

Our manufacturing processes comply with the IPC-A-610 Class 3 workmanship standard for products requiring high reliability, such as those used in life-support and aerospace systems. We maintain an on-site testing laboratory certified by the American Association for Laboratory Accreditation (A2LA) to the ISO/IEC 17025 standard.

SEL devices are designed to withstand the world’s most challenging environments, exceeding all commercial standards for temperature, shock, and electric stress. An optional conformal coating gives electronic components extra protection against corrosion and contamination in marine environments and extreme conditions.

The mean time between returns for repair (MTBR) for SEL products is more than 250 years. This number includes unscheduled removals and unavailability for any reason—not only for a defect, but also for misuse, overcurrent, overvoltage, and external factors such as fire, water damage, or chemical corrosion.

By way of comparison, a reliability study based on 25 years of operational data shows that the unavailability time of SEL electronic relays due to failures and repairs is at least 10 times lower than electromechanical relays.
