    Rugged Computers

    When “uptime” matters, SEL computers provide
    dependable computation for critical infrastructure.

    Rugged Computer 2

    SEL computers are built to withstand harsh environments in utility substations, industrial control systems, and automation systems. Industrial computer systems require 24/7 availability and ease of service when necessary. SEL computers are designed with a focus on RAS—reliability, availability, and serviceability. By eliminating all moving parts (including rotating hard drives and fans) and using error-correcting code (ECC) memory technology, SEL compact industrial computers have a mean time between failures (MTBF) of 100+ years. Designed, manufactured, and tested to the same quality standards as our protective relays, every SEL computer comes with the unprecedented, ten-year worldwide SEL warranty.

    Versatile and Reliable Form Factors
    SEL offers a standard rack-mount server-quality industrial computer and a “mount-anywhere” compact industrial computer. SEL also offers optional PCIe expansion cards, power supplies, and third-party monitors.

    Designed and Tested to the Highest Standards

    • SEL computers feature no fans or moving parts.
    • SEL computers utilize the most reliable memory and storage available, error-correcting code (ECC) memory and single-level cell (SLC) SSDs.
    • SEL computers are designed and tested to exceed the rigorous industry standards required for harsh operating environments. SEL computers:
      • Absorb up to 15 g of impact
      • Tolerate up to 15 kV of ESD
      • Resist large electromagnetic fields and RF interference
      • Offer a wide temperature range of –40° to +75° C (dual-core)
      • Have up to 95% 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 computers provide a standard, no-questions-asked, ten-year worldwide warranty.
