LED Power Supply Automatic Testing System Features:
Open
• Open hardware platform, allowing for the addition or removal of various testing devices as per customer requirements (including devices with GPIB, RS-232, USB interfaces)
• Supports simultaneous testing of multiple single/multiple group output LED power supplies, significantly enhancing production line capacity
• Open software platform, allowing for the expansion of various new testing items and functions based on customer testing requirements
• Supports multi-lane barcode pre-scanning function, and supports barcode scanning during testing to improve overall testing speed
Universal
• Supports testing of various power supplies (LED power supplies, adapters/chargers, PC power supplies, inverters, communication power supplies, etc.)
• Complies with Energy Star (ENERGY STAR) and IEC 62301 measurement requirements
• Supports Manufacturing Information System (ShopFloor) interface
• Supports testing of various power supply parameters under CV.CC.CR.LED modes
• Optimized display mode, arbitrarily combined hardware configuration
Professional
• Supports complete testing of LED driver power supplies
• Can accurately read the average current and effective current of the tested LED driver
• Can easily start low-power LED driver power supplies without pulling down the LED driver due to the large current surge from starting the electronic load
• By setting realistic LED turn-on threshold values and post-turn-on operating point resistance through the system, the test current and voltage waveforms are very close to real LEDs
• More realistic high-frequency current waveforms
• Dimming function testing: dimming current, dimming frequency, dimming cycle (requires additional related hardware devices) The LED Power
