R&D – Design Validation (DVT) Automated Test System

Design verification test - automated test systems - Chroma Systems Solutions

Design verification and validation tests push the specs beyond production testing. Chroma’s automated DVT systems help design engineers meet their initial or modified design requirements, specifications, and regulations. Our expertise in power conversion test enables us to design and deliver high performance turnkey automated test systems backed by a global customer support system. While we are integrating your automated test system, we can also fabricate custom test fixtures simultaneously at our design facility in Southern California.

Our DVT automated test system is based on our C8000 platform which uses a unique test command optimization technology to prevent sending repetitive control commands to the system hardware devices. This improves system test speed dramatically and, when used with our PowerPro III software, makes it highly efficient as a closed or optimized auto test system.

To meet power supply test requirements, the C8000 Auto Test System has 56 ready-made test items built in. Users may create new test items or edit existing items based on new test requirements using the on board editing function. This provides users unlimited capabilities to expand testing.

With powerful reporting, statistical analysis, and management functions, the C8000 Test System platform is able to generate many test documents as well as allowing control of system administration tasks. Test results and statistical reports are equally important for R&D evaluation, QA verification, and mass production tests, and with these functions built in to the system. A great deal of time can be saved, reducing the amount of manual paperwork that is required.

Working under Windows 98/NT/2000 or higher operation system, Chroma 8000 Power Supply Auto Test System is able to get all the resources provided by Windows; thus, it can easily export the test results to network or to your web-page for remote manufacturing monitoring.
