In installation site, how to to judge whether the power supply is normal or not?

Expert answer:

Hello, thanks for using our products! After you connect the power supply, check whether the indicator light of the power box turns on or not? If the conditions permit, you can use the universal meter. The input voltage is about 220v AC, and the output voltage is about 12v DC, which is normal.
