As is well known, anything that is used for a long time will malfunction, and of course, switching power supplies are no exception. So the question is, do you know the reason why the on/off power indicator light keeps flashing? What is the reason why the switch power supply has no output and the power indicator light is on? Let's learn more together below.

The output voltage of the switching power supply is indicated by the flashing power indicator light. This indicates that there is a short circuit fault on the secondary side, which is protected by the short circuit. It is also possible that the primary field-effect transistor of the switching power supply is damaged, and it is possible that the coil of the switching transformer is short circuited. The indicator light of the switch power supply keeps flashing, which is most likely due to aging of a certain component or short circuit of the load. After overheating, a self-protection function of the circuit is activated, causing it to turn black. After turning black, due to the lack of current, the temperature returns to normal and it lights up again. It should be noted that both short circuits and high temperatures can cause flashing. At this time, the output voltage should be appropriately reduced to reduce the output current.

Power indicator lights belong to the lighting industry and are subdivided into a category of indicator lights, which have been recognized by a large number of customers. The indicator lights on the system front panel and power supply devices are used to indicate the power status of the system. The power button controls the power supply of the input system power device. The power button indicator light can provide information about the power status. The power indicator light is actually a type of indicator light. The number of consecutive flashes of the power indicator light represents the indoor unit fault code. Power supply indicator light: Each hot swappable power supply device has an indicator light that can provide information about the power status, faults, and the presence of the power supply.

Indicator light code:

Illuminated: indicates that the system is powered on and can operate normally.

Not lit: indicates that the system is not powered on.

Flashing: indicates that the system is powered on, but still in a waiting state.

Discussion on Maintenance Experience of Switching Power Supply

1. When the switching power supply fails to start, we usually need to check whether the switching frequency is correct, whether the protection circuit is blocked, whether the voltage feedback circuit and current feedback circuit are okay, and whether the switching transistor is broken.

2. Switching power transformers generate heat or make a sizzling sound, usually due to incorrect switching frequency.

3. The output voltage of the switch power supply is usually indicated by a short circuit on the secondary side when the power indicator light flashes.

After reading the above introduction, I believe everyone has a further understanding of the reasons for the flickering output of switch mode power supplies.
