Lawrence Lee and Robert Nishimoto, skilled businessmen with a talent for innovation and attracting a top-level management team to Jasper. The result was a dynamic organization that helped lead to the formation of the commercial switcher industry, and remains a leader in the category due to the depth of experience of its management team.
Since the beginning, all Jasper Electronics products have been designed in the USA, then manufactured overseas. This provides the best possible combination of leading edge technology and quality engineering, with the ecnomies of offshore production. Subsequently, Jasper has added low-cost Chinese products to its portfolio. The quality and value of this approach has led to continuous growth, with Jasper Electronics among the fastest growing companies in the industry. Exceptional engineering of standard, modified standard, custom products, and systems ranging from 5W-10,000W are all backed with a policy of 100% customer satisfaction. Currently, aggressive efforts to enter newer markets in solar power, Micro TCS, and medical fields are being developed.
Today, Jasper Electronics and their subsidiary Lien Engineering operate from facilities in the USA, Malaysia, Japan, and China. Each facility is RoHS compliant, and operates under disciplined design and manufacturing processes that are ISO9001-2000 certified. In recognition of the increased focus on sustainable and environmentally friendly manufacturing, Jasper is extremely proud to have been recognized by the larger Japanese companies and USA contract manufacturers that meet the standards of the Green Parter Program. They continue to maintain and enhance the standards that are expected of their customers.
