Our History

  • Quindar is Founded
    Founded in 1960 as Quindar Electronics Incorporated, QEI was an early adopter of solid-state technology for industrial applications with the introduction of the first transistorized voice frequency (audio tone) telemetry products for electric network monitoring and control applications. Quindar rapidly became the leading supplier of such products to the electric...
  • The Advent of Microprocessors
    As we entered our second decade of operation in 1970, new technical developments presented significant opportunities with the maturing of the minicomputer technology and the advent of microprocessors. We immediately took steps to capitalize on these developments and established a software and firmware research and development group to bring applications...
  • SCADA goes Fully Computerized
    These research and development activities resulted in the introduction of the first fully computerized SCADA system in 1974. The system included a minicomputer-based master station with a standard, user configurable software package (SUPERCOMPILER II) and a microprocessor-based intelligent RTU (Quindett V). This was also the first application of intelligent RTUs...
  • Quindar becomes QEI
    In 1975, the company was reorganized and its name was shortened to QEI Inc. (Quindar Electronics Incorporated) and continued to serve the same markets with innovative products and systems.

The QUICS 3000 was widely deployed in a large number of electric utility and transit applications. The RTU architecture and construction were hardened specifically for application in high...
  • Advancements in The 80’s
    In the 1980’s, QEI introduced new master station software products that resided initially on Digital Equipment Corporation’s PDP11 line of minicomputer platforms and by the middle of the decade, they were ported to the VAX family of platforms. System availability and reliability are of paramount importance in both transit and...
  • 6CPP6 and 6ACP5
    As substation and feeder automation emerged at electric utilities, QEI responded with both system and substation level applications. Peak demand reduction and automatic VAR control were two key applications that provided significant short-term payback to utility customers. In response to market needs, QEI introduced a family of fourth generation RTU...
