Electrical aging bench
This bench is dedicated to electrical aging tests and heating tests on power connection components.
Its principle is to make thermal cycles by passing a regulated alternating current in a test loop.
It also allows injecting positive or negative dc current to make accurate resistance measurements.
It is designed to operate 24/24 for long-term duty in both modes “thermal aging” and “overloads”.
- Loop voltage up to 6V AC
- Current regulation from 0 to 1500A
- Temperature regulation from Ta to 200°C
- Stabilized measurement current +/- 100A DC
