Input Characteristics Test (AC) • Measures the input voltage, current, power, power factor...
Fundamentals and Harmonics In complex periodic oscillations, both fundamental and harmonics are involved. The sine wave component equal to the longest period of the oscillation is called the fundamental wave. The frequency corresponding to this period is called the fundamental frequency. The components of a sine wave whose frequency is an integer multiple of the fundamental frequency are called ha...

As we known the quality of LED lighting products depend on two points: One is LED chip(light source); Second is LED power driver. In the practice, there only have few company can provide qualified LED chip such as PHILIPS, OSRAM and CREE in the market. Generally, the LED chip have very small change to get quality problem, but we heard many news about low quality LED lighting products was found and...
Some customers suspect the accuracy of the WT2080 because there is some differences of the test result between LISUN WT2080 LED Power Driver Tester and multimeter when testing LED power driver. In fact, the test results are different because the test principle is different: the WT2080 test result is the real effective value (RMS), the multimeter test result is the average value. LISUN WT2080 is ac...
The LED is a light-emitting diode, and its characteristic curve is basically the same as that of a normal diode. When the applied voltage reaches the diode conduction voltage, the slight change of the applied voltage can cause a great change in the diode current. The constant current is used to ensure that the current in the LED is constant. No matter how the voltage changes, the current flowing...
