The switching power supply is the component with the shortest application life in the display screen system. Therefore, when choosing this product, our company chooses the well-known Baina power supply in the industry, which has the following performance characteristics:

1. The ripple of the DC output of the power supply is small, and the transient response is fast: the stable voltage output of the power supply is beneficial for the anti-interference of the circuit powered by it, ensuring the stable operation of the circuit.

2. Protection circuit: As the usage temperature increases, the power supply will automatically protect and stop acting, which can increase the lifespan of the display screen. In addition, in the event of misoperation of the power supply, the circuit will automatically protect itself, which not only ensures the lifespan of the power supply itself, but also protects the safety of the entire power supply line.

3. Long service life: The power supply is a frequently and continuously used component in LED display screens, and its service life directly affects the normal use of the display screen. Therefore, long service life is a consideration when selecting a power supply.

4. Adjustable output voltage: Due to the particularity of the LED display screen industry, it is required to change the working current of the LED light by adjusting the power supply voltage under certain circumstances, thereby changing the brightness of the LED. Therefore, in the design of energy-saving solutions, 4.2-5V power supply has low power consumption and saves 20% energy
