Company Summary

Online Power Supply, Inc. (Ops) is focused on research, development, and sales of technology related to improving the performance of Ac-Dc power supplies for applications in the industrial, data storage, commercial, communications, computer, governmental, medical and military markets. The Company's first product, the Ops-U-500-385 Power Factor Corrected (Pfc) Front-End Module, solves the size, weight, reliability, efficiency, operating temperature and thermal deration power loss problems. The Pfc Front-End features efficiency greater than 97% and significantly decreased complexity, size and weight. The Company's customers no longer have to over-specify output requirements because there is virtually no magnetic thermal deration, which also eliminates the need for fans or other ventilating measures. Follow-on single output and multiple output products will utilize similar technology and design.
