Project Overview

A Sutter high intensity 300W xeon light source was used in the client’s microplate imaging product line. During TUV safety testing, single fault tests were performed on the lamp. When a single fault to the cooling system was tested, the light source overheated with combustion of some internal components. Client contacted ZoZo Engineering to review applicable safety standards, to perform the necessary studies, and develop custom electronics to protect the product in the event of a single fault failure. ZoZo Engineering finished the development by obtaining safety agency approval and releasing a retrofit manufacturing package.
