What is the PFC of power supply and what is the function?

Power factor correction is abbreviated as PFC. it is mainly used to improve the ratio of effective power to apparent power at the input of a switching power supply. It is one of the common circuits in switch mode power supplies. Generally, the power factor of the input end of the model without PFC circuit is only around 0.4~0.6, while the active PFC circuit can reach more than 0.95. The correlatio...

Why do LED power supplies need high efficiency?

The LED power supply is an important component in the LED lighting system. During the use of the LED power supply, a certain amount of heat will be generated according to the quality of the LED power supply design, and heat is the biggest killer of the light decay of the LED power supply. Therefore, if the heat generation is to be small and not obvious, the efficiency must be high. This requires a...

0-10V dimming principle

The power supply is designed with a control chip. When the 0-10V dimmer is connected, the output current of the power supply is changed through the 0-10V voltage change, and the light is reduced. For example: when the 0-10V dimmer is modulated to 0V, the current drops to 0, and the brightness of the light is turned off. When the 0-10V dimmer is adjusted to a maximum of 10V, the output current will...
