The Chroma LCD Inverter Auto Test System model 8490 is the ultimate solution for LCD inverter. It not only test traditional DC to AC inverter but also the LIPS (LCD Integrated Power Supply) type that combines adapter and inverter in one board.
It has wild variety of choices in hardware, such as AC/DC Source, Power Analyzer, Electronic Load, DMM, Oscilloscope, Timing/ Noise Analyzer , OVP/Short Tester and ON/OFF Controller. And 3 PCI interface cards-Measurement Card, Control Card, DMM Card to measure all of the inverter parameter. Combining with the open architecture system software platform - PowerPro III, it gives users a flexible, powerful and cost effective auto test system for both inverter and LIPS type testing.
Test fixture has been the most critical ingredient for LCD inverter ATS due to the inverter is very easy to be influenced by loading effect that from measurement circuit and cable (See the fixture module equivalent capacitance in test fixture specification). Chroma LCD inverter auto test system model 8490 provides standard and various test fixtures such as probe pin design for those inverters that are keen in reducing loading effect. All fixtures use insulation module design. Two different modules can be selected (standard & high current module) for different types of inverter. The standard module is for CCFL inverter while the high current module for EEFL inverter. Each module built-in 5 high voltage relay to guarantee operating in high voltage environment. Furthermore two different resistors can be added on the fixture for loading selection.
With the powerful report, statistic and management functions, Chroma LCD Inverter Auto Test System model 8490 is able to provide complete tools to generate various test documents and improve system administration. Since the test and statistical reports are equally important nowadays for R/D evaluation, QA verification and mass production tests. So these save users a great deal of time for paper work.
Working under Windows98/2000/NT/XP operation system, Chroma 8490 LCD Inverter Auto Test System is able to get all the resources provided by Windows; thus, it can easily export the test results to network or to your web-page for remote manufacturing monitoring.
