Throughout our experiences we found out that most LED strip light products operate on low voltage DC. Common DC voltages used are 12V and 24V.
First and foremost, check that the power supply is rated for the correct voltage that matches the LED strip voltage. Under-voltage to the LED strip will result in the LED strip not working, and over-voltage will burn out your LEDs.
Secondly, make sure that the power supply capacity is sufficient for the length of LED strip being used. This can be calculated by looking at the LED strip’s specifications sheet, which typically lists the current or power draw per length.
