There is a problem with the switching power supply
You can look at the nameplate of this switching power supply. The input is AC power 220V, and the output is a DC stabilized power supply of 24V5 amps. If this switching power supply fails, what is the phenomenon?
First of all, the light is definitely not on, because the power of this light is controlled by a switching power supply, and secondly, no matter how many times the remote control is pressed, the remote control will have no response, whether it is a WiFi controller or an infrared controller, the controller There should be a feedback light. If this light does not light up, then there is a problem with the power supply.
The detection method, if you have an electric pen or a multimeter on hand, measure whether the power provided by the positive and negative poles is 24V, and observe whether the power supply fluctuates, because the probability of a problem with the switching power supply in the lighting circuit is very, very large, so- The general lighting problems are mostly switching power supply problems.
There is a problem with the remote control
This remote control terminal can be seen from the nameplate that it supports WiFi, and like this low-voltage controller-there will be no problems, but there are individual cases, so at this time we use mobile phone remote or infrared remote control. If the controller does not respond, but the power light is on.
Then there may be a problem with the controller. This is the first point. The second point, if we press the switch and the controller also has feedback, but the light does not turn on, provided that the light is intact, then the controller does not have a good switch control of the power supply, and it can be judged. The reason is that there is a problem with the controller.
The prerequisite for judging whether the controller is damaged is to ensure that the lighting is normal, and to ensure that the power supply to the controller, that is, the 24V DC power supply is normal.
