The Distributed DC Power Supply Unit is a new type of DC power equipment, primarily used in small switch stations and at the user's end. It provides a reliable uninterrupted power supply for secondary control circuits (such as intelligent terminals like microcomputer protection and indicator lights, analog indicators, etc.), preventing the loss of protection function in microcomputer protection during AC power outages. It also addresses issues caused by overvoltage and harmonics that lead to the failure of UPS, thereby rendering microcomputer protection ineffective. Additionally, it can supply DC operation power to primary switching equipment that meets the power requirements of the unit, such as spring mechanism vacuum circuit breakers, permanent magnet mechanism vacuum circuit breakers, and electric load switches.
The distributed DC power supply unit features both AC input and PT input options, offering various output specifications ranging from DC220V to DC24V to meet diverse usage scenarios. The unit's output power can reach up to 1200W, catering to different load requirements.
The distributed DC power supply unit is compact in size, easy to install and wire, and suitable for installation within various types of switchgear. It offers increased reliability and cost-effectiveness (more pronounced for small-scale end-users) compared to conventional 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 Distributed DC Power Supply Unit employs high-frequency power technology and utilizes an automatic charging management module to maintain the battery pack, significantly extending its service life 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 personnel.
