35 Years of Manufacturing Experience.

Low Cost Frequency Conversion & Ground Power Solutions.

Failsafe (or Rulix in some territories) is a UK manufacturer with more than 30 years experience in the manufacture of high powered frequency converters and rectifiers. The design emphasis has always been on dependability, durability, ease of use and the low cost of ownership. Many converters made by the company as far back as the 1980s are still in full operation and with the advent of the new Failsafe “ABLE” generation of converters this same reliability is available in even more compact and cost effective packages.
