The digital silicon cabinet is the carrier that realizes high power load dimming, and is also the core hardware of the dimming system. The CD80-A silicon cabinet is a dimmer with high control accuracy and high performance using digital decoding trigger control technology. Its DMX input interface uses optical isolation technology, high-precision, high-speed digital trigger system (lighting range of 1-100%, dimming curve 10, dimming precision 1024). Strong anti-interference, simple debugging, the system is not affected by temperature, voltage and other environmental effects, the system can meet the output voltage consistency requirements stipulated by the national standard first-class machine without debugging, and does not need to carry out light point, consistent maintenance and adjustment . The system adopts the ISP online system programmable large-scale integrated circuit, and the hardware reliability is improved. The software uses the "watchdog" technology and fault tolerance technology to automatically detect the distribution system even if it is strongly interfered by the external power grid and transmission line. When the electric voltage fluctuates, the triggering conduction angle can be automatically corrected to suppress the flashing of the lamp and ensure its normal operation. The silicon cabinet and the dimmer station transmit signals in a photoelectric isolation manner, which avoids the accident of burning and destroying the dimmer station due to accidental reasons such as leakage and static electricity.
