Rugged Computers

When “uptime” matters, SEL computing platforms ensure reliable performance in the most demanding utility and industrial applications.

Versatile and Reliable Form Factors

SEL offers a range of hardware options, including a standard rack-mount server-quality model and a “mount-anywhere” compact model. All SEL computing platforms can be deployed as industrial computers running Windows or Linux operating systems, or as Blueframe application platforms. SEL also offers optional PCIe expansion cards, power supplies, and third-party monitors.

Designed and Tested to the Highest Standards

  • SEL computing platforms feature no fans or moving parts.
  • SEL computing platforms utilize the most reliable memory and storage available, ECC memory and single-level cell (SLC) SSDs.
  • SEL computing platforms are designed and tested to exceed the rigorous industry standards required for harsh operating environments. SEL computing platforms:
    • Absorb up to 15 g of impact.
    • Tolerate up to 15 kV of ESD.
    • Resist large electromagnetic fields and RF interference.
    • Offer operating temperature ranges as wide as –40° to +85°C (–40° to +185°F)
    • Have up to 95 percent relative humidity resistance.
    • Are immune to effects of corrosion with the conformal coating option.

Industry-Leading Warranty

While almost all industrial computer manufacturers provide a two- or three-year warranty, SEL computing platforms provide a standard ten-year, worldwide warranty.
