It can also be used for all kinds of step-down constant current sources. Most of the market does not have reverse connection protection and fan input ports, and the protection device required for precision light sources is added. Slow start for 30 seconds.

TTL modulation description: External 0-5V voltage signal (0 is off, 5 is on, the frequency determines the speed of the light flashing), if it is just a long-bright light source, this function can be ignored.
