ATE-2 LED Driver Automatic Test System
ATE-2 LED driver automatic test system is applied to the production line for the finished products testing. With features of simplified operation and nice-looking, the workers can operate it at very short time. This system can meet the requirements of IEC62384, GB24825-2009 and other relative standards.
Characteristics:
•This equipment adopts the special designed electronic load to imitate the V-I curve of LED.
•The normal LED driver has the disadvantage of high ripple, so it will have big deviation when it drives the traditional electronic load. For this equipment, the electronic load is update, so that to approach the real LED load.
•This system contains a programmable frequency conversion power supply to ensure fast switch and choose the input voltage and frequency of tested driver.
•The test equipments, electronic load and programmable frequency conversion power supply in this system are special developed and designed to meet the LED driver test requirements.
•This system includes 2 groups (left and right); the 2 groups can work in turn, so that to improve the work efficiency. For example, if the left is on working, then the right can make wire connection.
•It can test 4 LED drivers input and output at one time.
•The equipment can connect with electronic load and LED load, the two difference loads can be fast switch under the control of computer.
•Enable to print out the series number and parameters of sub-quality products by working with a micro-printer,
•Enable to achieve the barcode record function by working with a barcode scanner.
•The test report can be saved as Excel file for consult, statistic and analysis purpose.
•Good software interface to freely choose the difference parameters combination, so that to meet different demands. All the parameters can set limit, and with the quality analysis function.
System function:
•Low voltage test and surge current test:
Full-load test includes:
Input: Voltage, current, power, power factor, frequency, harmonic and 2 to 11 times harmonic component
Output: voltage, current, power, ripple wave, efficiency
Steady state test includes:
Steady state 1, steady state 2, steady state 3. The chopped wave of power (enable to test dimming lights), voltage, and frequency in each state can be set separately; the other parameters are same as the full-load test.
Linear adjustment rate test; load adjustment rate test
•Over output voltage (current) protection test, under output voltage (current) protection test
•Output shorten circuit protection test, output open circuit protection test
•Stabilization time test; cut off time test
•Capacity discharge function
•Barcode record function
