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 Short /OVP 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.

The 8000 test system uses a unique test command optimization technology to prevent repetitive control commands from being sent to the system hardware devices. This improve test speed dramatically and makes the Chroma 8000 an ideal choice for both high speed production applications as well as design verification.

The 8000 test system includes a sophisticated test executive which includes pre-written test items covering almost all industry standard power supply tests. User may also create new test items by using a special test item editing function. This gives users the capability to expand the test library unlimitedly.

PowerPro III also includes power ful report, statistic and management functions, making the s ys tem capable to generate var ious tes t document s and per forming s ys tem administration. Because the test and statistical repor ts are critically impor tant in modern factories for R/D evaluation, QA verification and production tests, these functions are an integral part of the system.

Working under Windows 98/NT/2000/XP/7 the model 8000 provides test engineers with a dedicated power supply test system in an easy-to-learn Windows environment and allow access to resources provided by Windows.

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 linein 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.
