When switching devices, do not reverse the order of light console and silicon box power supply. . The silicon box is a silicon pile, but it is actually a big resistor. The power connection method is to avoid reversing the order of light console and silicon box power supply when switching devices. Function: Using silicon stack can reduce the voltage and adjust the brightness of the lamp. Silicon box is a dimming device, which uses SCR to control the current intensity, and then realizes the adjustment of light and shade, flicker and so on. The existing silicon box has strong specificity.
