In modern electronic systems, particularly in applications such as CCTV surveillance, LED displays, and industrial automation, reliable and efficient power supply solutions are crucial. Among the most common choices for providing 24V DC power are 24 volt dc adapter and 24V DC SMPS (Switched-Mode Power Supplies). While both serve the same basic function—delivering 24 volts of direct current—their internal design, performance capabilities, and application suitability can vary significantly.
