公司创立于1990年，引进国外先进的电源产品的技术和管理。通过吸收、消化、提高，成功研发了全固态中频、超音频、高频电源、智能化功率控制器、智能化PWM交流调压器、IGBT高频逆变直流电源，有源滤波器等产品。产品多次列为科技部创新基金项目及国家火炬计划项目，公司被评为江苏省高新科技企业及重合同、守信誉企业，到目前为止，已有几千套全固态中频、超音频、高频电源在国内外感应加热、热处理、焊管行业应用；有近三万台功率控制器，在各种电加热炉上及各种真空炉上得到应用；从2010年进入的晶体生长行业也有了近五千台的应用。Eastone was established in 1990. We introduced advanced foreign power supply product technology and management. And we digested and improved the technology, finally we researched and developed all-solid medium frequency power supply, ultra-audio frequency power supply, high frequency power supply, intelligent PWM AC voltage regulator and IGBT high frequency inverting DC power supply, APF etc. Our products have been classified as Innovation Fund Project of MOST and National Torch Plan Project for many times. Our company is awarded High and New Tech Enterprises of Jiangsu Province and Re-contract and Trustworthy Enterprise. We have so far thousands of all-solid medium, ultra-audio frequency and high frequency power supplies applied to induction heating, heat treatment and welding pipe at home and abroad. And about 30000 power controllers are applied to various electric heating and vacuum furnaces. Also we have already about 5000 power supplies applied since we entered crystal growth industry 2010.
