How to judge whether the power supply is normal at the installation site?
Expert answer:
Hello! Thanks for using our company's products! After you connect the power, check whether the indicator light of the power supply box is on. If conditions permit, you can use a universal meter to test it. The input voltage is about 220v AC, and the DC output voltage is about 12v, which is normal.
