In the monitoring system, cameras, transmission equipment, and video recorders all require a stable power supply. Switching power supplies can provide reliable DC power to ensure the continuous operation of the equipment and avoid monitoring interruptions caused by unstable power supply.
Advertising light boards usually use low-voltage DC light sources such as LED lights. Switching power supplies can convert AC power into suitable low-voltage DC power to provide stable current for LED lights, etc., to ensure the brightness and life of advertising light boards.
