AI Technical Summary
Existing EMC testing equipment is inconvenient for conducting interference power tests, and additional signal leakage affects the test results.
An EMC testing device was designed, which adopts a combination structure of guide rail, power absorption clamp and narrow-pitch conveyor belt. The power absorption clamp is driven to slide on the guide rail by drive roller and throttle, maintaining a safe distance between the test personnel and the equipment and avoiding frequent movement.
This eliminates the need for frequent movement of the power absorption clamp by the tester, reduces electrical interference introduced by manual operation, and improves the accuracy and convenience of testing.
