Single power switching power supply

A single power switching power supply outputs the required DC voltage through a power input, rectification filtering, transformation, voltage stabilization, and other circuits. The single power supply circuit has a simple structure, convenient design, and is suitable for situations with a small voltage range. In addition, single power switching power supplies also have advantages such as small size, light weight, and low cost, making them widely used.

Dual power switching power supply

Dual power switching power supply

Dual power switching power supply refers to the addition of a backup power input and output on the basis of one power input and output. When there is a problem with the main power input, the backup power supply will automatically start and provide power output for a certain period of time to ensure the continuity and stability of equipment operation. Dual power switching power supply is suitable for situations with very high requirements for power supply. For example, important equipment such as data centers and communication base stations.

The difference between single power supply and dual power supply

The difference between a single power supply and a dual power supply lies in the number of power input and output channels. A single power supply only has one power input, while a dual power supply has two power input channels, and one of the backup power supplies can automatically switch to the working power supply in the event of a failure of the main power supply. In addition, the dual power switching power supply also requires additional circuit modules such as backup switches, self start, and monitoring to ensure seamless switching of the backup power supply in the event of a main power failure.

In general, single power switching power supplies are suitable for situations with small voltage ranges and low requirements for power supply, while dual power switching power supplies are suitable for situations with extremely high requirements for power continuity and stability. When selecting a power supply scheme, it is necessary to select a suitable switching power supply based on the actual application scenario and power supply requirements.
