FCPSU-UNI2450U V2.1 is a power module (PSU) designed to provide stable and reliable power supply for various electronic devices. Its output power is 2450 watts, with a working voltage of 110-240V, suitable for use in different regions and power standards. V2.1 refers to the version number or revised version of the power module model. A good grounding of FCPSU-UNI2450U V2.1 is an important condition to ensure the reliable operation of PLC, which can avoid accidental voltage surge hazards. The grounding wire of the PLC should be connected to the grounding terminal of the machine, with a cross-sectional area of no less than 2mm2 and a grounding resistance of less than 100 Ω; If an expansion unit is to be used, its grounding point should be connected to the grounding point of the basic unit. In order to suppress interference on the power supply, input and output terminals, a dedicated ground wire should be connected to the PLC, and the grounding point should be separated from the grounding point of power equipment (such as motors); If this requirement cannot be met, it is also necessary to achieve common grounding with other devices and prohibit serial grounding with other devices. The grounding point should be as close as possible to the PLC.

Generally speaking, these types of modules are referred to as load (POL) power supply systems or point of use power supply systems (PUPS). Due to the many advantages of modular structures, modular power supplies are widely used in communication fields such as switching devices, access devices, mobile communication, microwave communication, optical transmission, routers, and automotive electronics, aerospace, etc. Especially in recent years, due to the rapid development of data services and the continuous promotion of distributed power supply systems, the growth rate of modular power supplies has exceeded that of primary power supplies. The modular power supply has isolation function, strong anti-interference ability, built-in protection function, and is easy to integrate. With the widespread use of semiconductor technology, packaging technology, and high-frequency soft switching, the power density of modular power supplies is increasing, the conversion efficiency is getting higher, and applications are becoming simpler.
