What are the basic classifications of non-isolated power supply(2)
AC-DC the 110 v input power supply supply is mainly divided into small power (3W~36W), medium power (50W~200W) and large power (>200W).
DC-DC the 110 v input power supply supply is mainly divided into micro power supply module (0.1W~3W), small power supply module (1W~30W), medium non-isolated power supply (50W~200W) and high power supply module (>200W).

vehicle
According to the input range, AC-DC power module is divided into conventional input (85~265VAC), three-phase four wire input (380VAC), and other AC voltage inputs.

DC-DC power module is divided into stable voltage input, wide range voltage input and ultra wide voltage input according to the input range.
A modular power supply is a power supply that can be directly mounted on a printed circuit board and can be used for application-specific integrated circuits (ASICs), digital signal processors (DSPs), microprocessors, memories, field programmable gate arrays (FPGAs) and other Digital or analog loads provide power. Typically, such modules are referred to as load (POL) power supply systems or point-of-use power supply systems (PUPS). Due to the obvious advantages of the modular structure, modular power supplies are widely used in switching equipment, access equipment, mobile communications, microwave communications, optical transmission, routers and other communications fields, as well as automotive electronics, aerospace, etc.
supply
●The design is simple. Power is available with just one power module, with a few discrete components. ● Shorten the development cycle. The module power supply generally has a variety of input and output options. Users can also repeatedly stack or cross stack to form a building block combined power supply to achieve multiple input and output, which greatly reduces the prototype development time.
●Change is flexible. If the product design needs to be changed, simply convert or parallel another suitable power module.
4. According to output accuracy:
AC-DC power module is divided into regulated output and adjustable output. DC-DC power module is divided into non regulated output, regulated output and adjustable output.
