About Ritronics Inc
Ritronics Inc was established in 2011 in Warwick, Rhode Island, to serve the aerospace, defense, and transportation sectors with ruggedized power supplies. The company designs and manufactures standard COTS and custom AC/DC and DC/DC power supplies ranging from 36 W to 1,000 W, built to withstand extreme temperatures, shock, vibration, and EMI‑dense environments. Its engineering team handles requirements analysis, topology selection, prototype development, design validation, and environmental and EMI/EMC test support, scaling to production with full traceability. Ritronics also provides third‑party logistics services — procurement, kitting, warehousing, and assembly — through its sister company, Calgreg Electronics. Ritronics serves defense primes, program managers, and design engineers across aerospace, defense, and transportation markets. Its products are qualified to MIL‑STD‑461G for electromagnetic compatibility and meet FCC Part 15 Class B and CISPR 22.2 Class A requirements, supporting programs with decades‑long lifecycles. The firm emphasizes domestic engineering and manufacturing oversight, direct engineer‑to‑engineer access without call centers or distributors, and standards‑mapped documentation to streamline qualification. It was founded to solve power problems that off‑the‑shelf suppliers won’t touch, offering long‑lifecycle support for programs measured in decades rather than product cycles.
