An integrated DC power supply unit is a new type of DC power equipment, primarily used in small switching stations and at the user's end, providing a reliable and uninterrupted power supply for secondary control circuits (such as intelligent terminals like microcomputer protection and indicator lights, analog indicators, etc.). It avoids the loss of protection due to the failure of microcomputer protection when AC power is lost, and solves the issue of UPS failure caused by factors like overvoltage and harmonics, which leads to the failure of microcomputer protection. Additionally, it can also supply power to primary switching equipment that meets the power requirements of the unit, such as spring mechanism vacuum circuit breakers and permanent magnet vacuum circuit breakers.、Supplies DC operational power for electric load switches, etc.

The integrated DC power supply unit features both AC input and PT input options, offering output specifications ranging from DC220V to DC24V. It caters to various usage scenarios. The unit's maximum output power reaches 800W, meeting the requirements of different loads.

The integrated DC power supply unit is compact in size, easy to install and wire, and suitable for distributed installation within various switchgear models. It offers increased reliability and cost-effectiveness (more pronounced for small-scale end-users) compared to standard DC screen systems. It also saves space, reduces wiring losses and installation work, and is easy to maintain, providing a new choice for the reliability of power system supply.

The integrated DC power supply unit employs high-frequency power technology, and the battery is maintained with an automatic charging management module, significantly extending the battery's lifespan and ensuring safer and more reliable operation. The unit is equipped with communication and alarm functions, enabling convenient remote automated management without the need for on-site staff.
