The PM860 Power module is a power supply that can be mounted directly on a printed circuit board and is characterized by providing power for application-specific integrated circuits (ASics), digital signal processors (DSPS), microprocessors, memory, field programmable gate arrays (FPgas), and other digital or analog loads. In general, such modules are called load (POL) power supply systems or point-of-use power supply systems (PUPS).

A complete power module is generally composed of input rectifier filter, single-chip switching power supply, high-frequency transformer, leakage clamp protection circuit, optocoupler feedback circuit, output rectifier filter, bias circuit and other parts, composed of these components of the power module is not only simple and clear design, small space, but also has high reliability and high stability.

Because the power module has the advantages of small size, high integration, high cost performance and the best performance index, only the simplest peripheral circuit can be used with a small number of discrete components. When the product design needs to be changed, just parallel or replace the power module. Therefore, power modules are widely used in many industries, especially in switching access equipment, mobile communications, microwave and other communication fields, automotive electronics, aerospace and other industries.

The advantages of the power module include:

Small size, light weight: The power module adopts a highly integrated design and can be mounted directly on the printed circuit board, so it is small size, light weight, easy to carry and use.

Energy saving and environmental protection: The PM860 power module has high efficiency and low power dissipation, which can effectively reduce energy waste and reduce environmental pollution.

High reliability: The power module adopts high-quality electronic components and advanced circuit design, which has high reliability and can ensure long-term stable operation.

Strong scalability: the output voltage and current of the power module can be adjusted, which can be customized according to different load requirements, and can be used in parallel and series, and has strong scalability.

Easy maintenance: The power module adopts modular design, easy to disassemble and replace, and has perfect protection function, which can effectively reduce maintenance costs and time.

The disadvantages of the power module include:

High cost: Because the PM860 adopts a highly integrated design and high-quality electronic components, its cost is high, and it is not suitable for some low-cost application scenarios.

High requirements for power management: The power module needs to accurately control the input voltage, output voltage, and current, which requires high requirements for power management and requires certain technical strength and experience.

Possible electromagnetic interference: The switching power supply used in the PM860 power module generates high-frequency pulses, which may cause electromagnetic interference to other circuits.
