CPCI-AC-6U-500

The CPCI-AC-6U-500 power module is an electronic device whose main function is to convert AC or DC power into a specific voltage and current DC power supply required by the device. This type of module can be directly soldered onto printed circuit boards, providing stable and reliable power supply for various electronic devices such as specialized integrated circuits (ASICs), digital signal processors (DSPs), microprocessors, memory, field programmable gate arrays (FPGAs), etc. The CPCI-AC-6U-500 power module is generally divided into two types according to the conversion method: AC to DC (AC to DC) or DC to DC (DC to DC). They are usually composed of input rectifier filters, single-chip switching power supplies, high-frequency transformers, leakage clamp protection circuits, optocoupler feedback circuits, output rectifier filters, bias circuits, and other parts. They have the characteristics of compact design, easy maintenance, cost and time savings, high power, high efficiency, and high stability. In addition, the operating temperature of power modules is generally divided into commercial regulations (0 ℃~60 ℃), industrial regulations (-25 ℃~71 ℃), military regulations (-55 ℃~85 ℃), etc., and appropriate temperature levels need to be selected based on the actual operating temperature range of the system. At the same time, the input voltage of the power module also needs to be selected based on the voltage provided by the front-end power supply and its range of variation to ensure that the power module can operate within the normal range. Due to the above advantages, power modules are widely used in communication fields such as switching devices, access devices, mobile communication, microwave communication, optical transmission, routers, as well as in industries such as automotive electronics and aerospace.
