LED Power Supply Automatic Test System Model 8491

Chroma 8491 LED power supply automatic test system can support simultaneous testing of multiple objects to be tested at a time, significantly increasing production line capacity, but also a variety of hardware options, including input AC power supply or DC power supply, accurate digital power meter, PCI interface cards, sensor units, sensor modules, and the industry's first specially designed for the LED power supply output pulling the load of the dedicated electronic load.

The system is paired with a PCI interface function card - LED power measurement and control card, whose main functions are to measure dimming current/frequency/cycle duty cycle and to provide dimming control signals (DC voltage, pulse width modulation, SM BUS) and energizing switch signals. In addition, the timing/noise measurement card can also be utilized for ripple current measurement at 20MHz bandwidth.

Chroma 8491 automated test system is equipped with standard test items optimized for the characteristics of the object to be tested (LED power supply for lighting). Users only need to define the test conditions and test specifications on the standard test items to test.

Chroma 8491 automatic test system software runs on Windows 7/10 or above, providing test engineers with a dedicated power supply test system in an easy-to-learn Windows environment and easy to use Windows resources.

Chroma 8491 automated test system is equipped with standard test items optimized for the characteristics of the object to be tested (LED power supply for lighting), the user only needs to define the test conditions and test specifications on the standard test items can be tested.

Optimized test items cover six categories of power supply test requirements, output characteristics (OUTPUT PERFORMANCE) to detect the general performance of the object to be tested, input characteristics (INPUT CHARACTERISTIC) to detect the input parameters of the power supply, and stability test (REGULATION TESTS) to detect the object to be tested in the input power supply and load changes in the Stability. Timing and Transient (TIMING & TRANSIENT) measures the transient state and the time of each event when power is turned on and off, Protection Test (PROTECTION TESTS) triggers the protection circuit of the power supply, and Special Tests (SPECIAL TESTS) provides special functions and methods to test the power supply.

The Chroma 8491 automated test system software platform, PowerPro III, provides users with an open software architecture suitable for a wide range of applications and products.The software for the Power Pro III automated test system, which runs on Windows 7/10 or higher operating environments, provides the necessary peripheral support.

Chroma 8491 automatic test system is suitable for modern large-scale mass production line, with support for Chroma Sajet Manufacturing Execution System (Manufacturing Execution System, MES) for the control and management of the test station, personnel, product serial number and test program, as well as the uploading of test data to the central server function, to achieve centralized management of the test program and data collection / report analysis and other applications to assist customers to complete the goals of the smart factory, improve product quality, efficiency, reduce production costs to create corporate profit maximization. The centralized management of test programs and data collection/report analysis are achieved to assist customers in accomplishing the goal of smart factory, improving product quality and efficiency, reducing production costs, and maximizing corporate benefits. In addition, Chroma can provide customized Shop-Floor control system services to link with existing MES in the customer's factory, and has assisted many world-class manufacturers to complete the MES system integration of real cases.

In addition, in response to the trend of Industry 4.0 fully automated intelligent production line, Chroma 8491 automatic test system also completes the system hardware equipment status self-test function, at the end of each product test, it will automatically carry out the status review of the hardware equipment, when there is an abnormality of the test equipment or the system, the Chroma 8491 system can be integrated with the digital I/O device, the output of the digital signal to notify the management center, and the local computer will record the "system start test time", "system end test time" and the occurrence of abnormal error messages for easy reference by users to adjust the maintenance cycle and deployment of equipment. Chroma 8491 system can integrate digital I/O devices to output digital signals to notify the management center, and record the "system start test time", "system end test time", and abnormal error messages in the local computer, which is convenient for users to trace the reference and statistics to adjust the equipment maintenance cycle and deployment.
