Switching Power Supply ATS
Comprehensive Test Items
The Model 8000 automatic power supply test system comes standard with an off-the-shelf test item library covering most industry standard
power supply tests. Unlike traditional ATE software, users do not need to have programming language background to create new test
items. Instead the Model 8000 allow users to use pre-compiled test items and to simplify defining test conditions and specifications.
The comprehensive test items cover 7 categories of power supply testing requirements. OUTPUT PERFORMANCE checks the general
performances of the UUT. INPUT CHARACTERISTIC verifies the input parameters of a power supply. REGULATION tests the stability of
the UUT under varying line-in and loading changes. TIMING AND TRANSIENT measures the transient state during turn-on, turn-off or
when events occurred. PROTECTION TESTS triggers the protection circuit of the power supply. Finally, the SPECIAL TEST and the
SPECIAL FEATURES provides means to test the most sophisticated power supplies when unique test routines are needed.
*These test items need to be created by users by using test item editor due to the variety of the UUTs.
And unlimited customized or user defined test items are allowed.
