Processing method of switching power supply alarm
The switching power supply failure caused by the above two reasons, the processing method is as follows:
1. Disconnect the load of the switching power supply, so that the switching power supply is powered on alone without load. At this time, the output voltage of the switching power supply will be abnormal, and the switching power supply will be replaced directly.
2. Before replacing the switching power supply, use a multimeter to test the resistance of the load of the switching power supply to see if the load is damaged due to abnormal power-off.
The above introduces the two reasons for switching power supply alarm, and the related treatment methods, I hope to be helpful to everyone.
