FAQ
Q1: Why is a specialized DC power supply needed for LED testing?
A: LEDs are current-driven devices. Testing requires a high-precision, stable constant current source with very low ripple to accurately measure their electrical and optical properties. A standard power supply may have current fluctuations that cause inaccurate readings and light output variations.
Q2: Can this supply simulate dimming for LED drivers?
A: Yes. Through its analog control input or digital interfaces, you can program rapid current or voltage changes to simulate PWM or analog dimming signals for testing driver response.
Q3: Is it suitable for high-power LED street light testing?
A: Absolutely. High-power models (e.g., 3kW, 6kW) can provide the necessary high current at low voltage to test drivers and modules for high-bay lights, street lights, and stadium lighting.
Q4: How does it connect to an automated test system?
A: With standard LAN (LXI), USB, and RS232 interfaces, it can be easily controlled by test software (like LabVIEW, Python) to run automated test sequences, log data, and pass/fail units in a production environment.
Q5: What is the difference between Constant Current (CC) and Constant Voltage (CV) mode for LED testing?
A: CC Mode is used to test the LED itself by driving it with a fixed current to measure its forward voltage (Vf). CV Mode is used to test an LED driver's output by applying a fixed voltage to see if it regulates current correctly. A quality LED test supply must excel at both.
