The bearing power of DC power socket is large, and the socket is not prone to fever and other phenomena. The inner core of the socket is made of high temperature resistant plastic material, and the DC power socket is not easy to deform at high temperature. Reasonable structure design, large plug distance, each plug of DC power socket can be used independently, will not affect each other. Socket shrapnel using high elastic phosphorus copper data, plug and pull times without fatigue, touch outstanding is not easy to show sparks. First, the DC-004A uses a reasonable design and is extremely easy to install. It is compact, lightweight and easy to use, while also using some user-friendly design, such as non-slip handle, waterproof and so on. Secondly, DC-004A has high quality stability performance, the detection mechanism can detect the power supply voltage and current. Stable power supply voltage and uniform current output ensure the efficient and stable operation of peripheral equipment. Third, DC-004A complies with international standards and adopts excellent electrical and electromagnetic design to ensure its good electrical performance and electromagnetic compatibility. The DC-004A is also resistant to abnormal conditions such as short circuit, overcurrent, and overvoltage, thus providing security for the device. Fourth, DC-004A has a wide range of applicability, suitable for a variety of stable DC power supply occasions. For example, loudspeakers, surveillance cameras, wireless communication equipment, industrial automation control equipment and so on can use it.DC-004A is manufactured with high quality materials and advanced production process, with precision circuit control and protection functions. Its excellent electrical performance can ensure the efficient and stable operation of external equipment. DC-004A is widely used in the fields of voice amplifier, surveillance camera, wireless communication equipment, industrial automation equipment, home lighting and small household appliances, especially for the need for highly stable power supply. In addition, DC-004A also has intelligent function, can display the working state of the power supply and output voltage, more convenient and reliable to meet the needs of users. In short, DC-004A is an excellent DC power socket with high security, intelligent operation, good electrical performance and electromagnetic compatibility, providing convenience and protection for users in various applications.
