The meaning of LED drive power efficiency and PFC Jun 23 ,2021
Efficiency is the percentage of the ratio of output power to input active power. This is a very important parameter of the triac LED drive power supply. The larger the value, the lower the heat generation of the power supply, which can improve the light efficiency and service life of the overall lum...

What is the working principle of dimming power supply? Jun 21 ,2021
The dimming power supply adjusts the brightness of the light by changing the output voltage and current of the power supply through the dimming signal input to the power supply. The biggest difference between the ordinary power supply and the dimming driver is that the ordinary power supply only has...

What is the principle of 0-10V dimming power supply? Jun 16 ,2021
The 0-10V dimming power supply is designed with a control chip. When the 0-10V dimmer is connected, the output current of the power supply can be changed through the 0-10V voltage change, and the brightness of the light can be adjusted. For example: when the 0-10V dimmer modulates 0V, the current dr...
