Isolated power supply and non-isolated power supply LED lamp boards are not completely common, because their input voltage and output voltage are different.
< br >
The input voltage of the isolated power supply is generally AC 220V, and the output voltage is DC 12V or 24V and other low voltages, so the isolated power supply is suitable for occasions with high voltage and small current, such as home lighting, advertising light boxes, etc.
< br >
The input voltage of the non-isolated power supply is generally AC 85-265V, and the output voltage is DC 3-60V and other high voltages, so the non-isolated power supply is suitable for low-voltage and high-current occasions, such as factory lighting, automotive lamps and so on.

The voltage and current of the LED lamp board should match the power supply, otherwise it will affect the service life of the LED lamp board or cause the lamp board to be damaged, so it is necessary to pay attention to its input voltage and current parameters when selecting the LED lamp board, and the type of power supply required (isolated or non-isolated).
