The Chroma Power Supply Automatic Test system Model 8000 is the ultimate solution for power electronic testing. The system includes a wide range of hardware choice such as AC/DC Sources, Electronic Loads, DMM, Oscillate Scope, Noise Analyzer and OVP/Short Tester. This flexibility combined with its open architecture software platform PowerPro III, gives users a flexible, powerful and cost effective test system for almost all types of power supply testing.


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.
