Several Indexes of Power Module

Power P = UI, which is the product of output voltage and output current.
The input voltage is divided into AC input and DC input.
The output voltage is generally DC output, but there is also AC output.
Working Temperature
Isolation voltage: isolation is to separate the output from the input. It has the following functions:
1). Current conversion.
2). To prevent mutual interference between input and output.
3). The signal characteristics of the input and output circuits are too different. For example, the package size of the equipment that uses weak signals to control strong current has pins, patches, and spirals.


The output includes single channel output, double channel output and multi-channel output. The power supply module is a power supply that can be directly mounted on the printed circuit board. Its characteristics are that it can supply power for application specific integrated circuit (ASIC), digital signal processor (DSP), microprocessor, memory, field programmable gate array (FPGA) and other digital or analog loads. In general, such modules are called point of load (POL) power supply system or point of use power supply system (pups). Because of the advantages of the modular structure, the modular power supply is widely used in the fields of switching equipment, access equipment, mobile communication, microwave communication, optical transmission, routers and other communication fields, as well as automotive electronics, aerospace and so on.
