ViSion was established in 1976 as a company specializing in adaptors, transformers and related electronic components. We are committed to provide high quality products and a "Customer First" attitude; we strive to be consistently superior to competitors in fulfilling customer's needs.

ViSion setup its own manufacturing facilities in China in 1991 and extended its plant area to a well-equipped 2nd production facility in 2002, manufacturing electronic components under the brand name ON-TECH and producing OEM products. While under expansion, in the early 1990's, we further expanded our manufacturing facilities to include plastic injection, bringing the entire manufacturing process under one roof.

ViSion has acquired the ISO 9001 accreditation from TUV Rheinland ever since 2000 and the ISO 14001 accreditation from TUV Rheinland in 2007. Jetronics has committed to maintain the environment protection and has implemented green, lead-free production. The ISO 9001:2000 and 14001:2004 international standards are implemented to establish the integrated management system of quality and environment to assure our products leave our factory with best quality.

Today, we specialize in Switching Mode Power Supplies, Coils, Adaptors, Transformers, Ballasts, IF Transformers, Torch, Sirens, and many more. Our products are in compliance with the international safety standard: UL, C-UL, TUV/GS, CE, SAA, etc.

Years of manufacturing experience and our dedication to high quality standard and excellent customer service have earned us to build up win-win situations with customers. ViSion' mission is to be a leading transformer manufacturer that supplies high quality products at competitive prices, with excellent services.
