Sansion power SXBP series test systems two operation modes: auto/ manual. Under auto mode, the operator only needs to set the voltage degree, withstand voltage time, then the system could find the resonance point and carry on the boosting automatically. The test report could be printed after test finished. Under manual mode, the voltage and current to be regulated by operator, and to find resonance point, print the test report manually.
Ex-work testing were completed successfully, all the test data was satisfied with the specifications.
