An integrated DC power supply unit is a new type of DC power equipment, primarily used in small switch stations and user ends to provide a reliable and uninterrupted power supply for secondary control circuits (such as intelligent terminals like microcomputer protection and indicator lights, analog indicators, etc.), thus avoiding the loss of protection function of microcomputer protection due to power failure of AC. It also solves the issue of microcomputer protection failure caused by factors like overvoltage and harmonics that lead to the failure of UPS. Additionally, it can supply power to primary switching equipment that meets the power requirements of the unit, such as spring mechanism vacuum circuit breakers and permanent magnet mechanism vacuum circuit breakers.、Supplies DC operating 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 can meet various usage requirements. The unit's maximum output power reaches 800W, capable of catering to different load demands.

The integrated DC power supply unit is compact, easy to install and wire, and suitable for decentralized installation inside various switchgear models. It offers increased reliability and cost-effectiveness (more pronounced for small-scale user terminals) compared to standard DC screen systems. It also saves space, reduces line losses and installation work, and is easy to maintain, providing a new choice for power system supply reliability.

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 service life and ensuring safer and more reliable operation. The unit features communication and alarm functions, allowing for easy remote automated management without the need for constant supervision.
