(I) Definition and Basic Principles
The 28V DC power supply has two electrodes, a positive and a negative pole. When the current is connected to the two terminal ports of the electrodes, the positive pole has a higher potential than the negative pole. Once connected, the circuit maintains a relatively stable potential difference on both sides. The current flows from the positive pole to the negative pole. The DC power supply converts energy during operation, allowing a device to pass a non-working current while maintaining a stable potential difference, which is sufficient to enable the device to operate normally. There are many types of DC power supplies, and the electrical properties and energy conversion processes of different types of DC power supplies vary greatly.
(II) DC Power Supply Applications
With societal changes, power requirements vary greatly across various industries and aspects of production and daily life. Particularly in many specialized sectors, power demands are even more stringent. These industries' communication equipment and operational systems possess certain levels of safety and confidentiality. The safety and stability of communication power are guarantees for the normal operation of industry information systems. The characteristics of the 28V DC power ensure that these specialized sectors will not experience losses due to power issues during operation.
