Rail-Grade Power Electronics Restoration Since 2006.

TELIS specializes in high-horsepower critical equipment that operates post-electricity generation.

If an asset conditions, converts, or controls power, we restore it to like-new — and in some cases, re-engineer it beyond original OEM specifications.

We restore, harden, and preserve power electronics including:

  • Inverters (Solar, Wind, and Utility-Scale)

  • IGBT Modules & Gate Drivers

  • Industrial Power Supplies

  • Control Panels & Logic Boards

  • Operator Displays & HMI Units
