A DC electronic load that can simulate LED electrical characteristics in a module + mainframe configuration.
The LED driver supplies the energy that serves as the light source for the LED and is designed as a constant current source for the LED. The characteristics of an LED driver differ from those of a typical switching power supply, but the structure is very similar. To evaluate an LED driver, it is possible to perform operational checks using actual LEDs, resistors, and electronic loads with CR/CV modes, but it can be challenging to meet the testing conditions. When evaluating an LED driver with a resistor, the relationship between voltage and current becomes linear, as shown by the blue line, which does not fully utilize the characteristics of the LED. When using a DC electronic load with CR/CV modes, it is desirable for both CR and CV modes to operate stably. However, during LED ON/OFF tests or dimming tests, the protection circuit of the LED driver may cause instability in the operation of the electronic load, posing a risk of not being able to conduct the tests successfully. Using actual LEDs as a load can lead to degradation issues over long-term use and requires significant labor to test various types of LED drivers. Chroma has prepared the 63110A/63113A/63115A, based on the 6310A series, to solve the testing issues for LED drivers.
