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