The Dimmer System is a product we have developed for companies operating in the defense industry, designed to be used in a solar laboratory project. The PLC in the system sends an angle value to the Dimmer card through the RS485 Port according to the desired light and radiation level, and the card performs Triac triggering in response to the relevant angle value. There are 32 dimmers, 2 pyranometers and 1 PLC in the system. Each dimmer card has the capacity to feed 8kW load.
