什么是三端双向可控硅调光电源

Triac technology is a technology with more than half a century. After triac dimming technology, the lighting industry has adopted PWM digital dimming protocol technologies such as 0 / 1-10V analog dimming, DMX512 and Dali. However, the triac dimming technology has its irreplaceable reasons. One is historical inheritance. The other is that it does not need a signal line, does not need to change the simplicity of the original line, has low cost and convenient construction, and is more popular with the engineering party. Therefore, the triac dimming power supply still occupies the largest market share of the dimming power supply. What is the triac dimming power supply?

Triac is only a discrete device, commonly known as thyristor. Because of its unique structural characteristics, it is widely used in two products: traditional fan governor and halogen lamp dimmer. Generally, its shape is designed as national standard 86 switch shape, so most of them call it leading edge triac dimmer, Subsequently, most of the rear edge dimming switches designed with MOS tubes are also called thyristor dimmers. During the period of rapid development of LED lamps, the driving power supply used with thyristor dimmers is collectively referred to as triac dimming power supply.
