Expert answer:
Hello! Thank you for using our products! The controller does not work, and if the power lamp and CPU light are not bright, check the positive and negative terminal of the power supply first. If the conditions permit, please use the universal meter to measure the power supply. The AC input voltage is about 220V, and the DC output voltage is about 12V, which is normal. Second, check whether the power connection port of the controller is energized. If the power supply is normal, please contact the salesman and we will deal with it as soon as possible.
