This client had an outdated high-voltage endurance life tester to qualify critical components for their Class III medical device. The software ran on an old version of Windows and spare parts were no longer available for many critical components. They needed a new, modern system delivered and qualified before the existing system failed beyond repair.
Andrews-Cooper developed a custom high-voltage test system designed for characterization and accelerated life testing of electrical components to be used in their Class III medical device. It was composed of two primary assemblies: DUT (device under test) Rack Assembly and Control Rack Assembly. The DUT Rack Assembly fixtures the DUT and associated custom electronics. It can be integrated into an environmental chamber or operated independently. DUT’s are mounted to two panels, each with a sixteen (16) DUT capacity. The panels are mounted to drawer slides, allowing easy loading and unloading of components with the panels in the extended position. The Control Rack Assembly is composed of two high-voltage power supplies, National Instruments PXI Chassis with PC controller, FPGA module, analog data acquisition module, high resolution monitor, and a 24VDC power supply all mounted in a 19 inch rack cabinet. The Control Rack communicates with the DUT Rack over a fiber optic signaling system for industrial environments resulting in high-voltage isolation, immunity from electro-magnetic interference, small signal cross-talk, and ground loop currents ordinarily present in copper wire signaling systems
