What is "Inrush Current" of led power supply?What will we notice?

The inrush current of an LED power supply is the initial surge of electrical current that flows into the power supply when it is first turned on. This surge of current can be several times higher than the normal operating current of the power supply, and it typically lasts for a very short period of time, usually a few milliseconds.

If the inrush current is not properly managed, it can cause several problems. First, it can cause the power supply to trip a circuit breaker or blow a fuse. Second, it can cause damage to the power supply itself, such as damage to the capacitors or other components.

To address the issue of inrush current, many LED power supplies are designed with inrush current limiters, which are circuits that limit the amount of current that flows into the power supply when it is first turned on. Inrush current limiters can be built into the power supply or can be part of the external circuitry.

If you notice that your LED power supply is tripping a circuit breaker or blowing a fuse when it is turned on, or if you observe any other abnormal behavior, it is possible that the inrush current is the cause. In such cases, it is recommended to consult with a qualified electrician or technician who can help you to diagnose and address the issue.
