PROJECT CONTEXT
From rated values to verified operating boundaries
A connector's maximum current-carrying capability decreases as ambient temperature rises. Derating tests apply electrical and thermal stress to establish a usable current-temperature relationship.
The platform coordinates power, measurement, data recording, and process control around the device under test, making the test sequence, critical states, and results visible in one working environment.
Engineering focus
Boundary determination
Observe whether temperature rise or contact resistance reaches the applicable criterion and identify the current-carrying limit.
Explainable results
Transform discrete measurements into an intuitive derating curve that supports connector selection and vehicle electrical safety margins.
Test workflow
Equipment, test conditions, and data are organized in repeatable stages.
Configure conditions
Define the device under test, environment, current steps, and measurement channels.
Apply stress
Increase current according to the test plan and maintain each required stabilization period.
Monitor criteria
Continuously acquire temperature and resistance data to evaluate the governing limits.
Build the curve
Compile results across ambient temperatures into the current-temperature derating relationship.
Delivered value
Verified boundaries
Make the relationship between temperature and current-carrying capability observable and comparable.
Better design decisions
Provide clearer validation evidence for harness, connector, and vehicle electrical system design.
Traceable test data
Retain process data and curve results for review, analysis, and subsequent iteration.
