There are a lot, and the automatic control system is the most.

In the instrument industry, there are indeed more finished power modules, such as Jin Shengyang and Mean Well.

However, if the power supply quality is relatively high, such as precision analog circuits, reference sources, ADCs, PLLs, etc., the power supply will be specially handled, and it will generally be built by yourself.

Power modules are used in all kinds of electronic and electrical equipment.

Power modules are generally used in high-power products, and the requirements are relatively high. Isolation voltage is required.

Power modules are power supplies** that can be mounted directly on a printed circuit board and feature power supply to application-specific integrated circuits (ASICs), digital signal processors (DSPs), microprocessors, memory, field-programmable gate arrays (FPGAs), and other digital or analog loads. In general, these modules are referred to as point-of-load (POL) power systems or point-of-use power systems (PUPS). Due to the advantages of the modular structure, the module power supply is widely used in switching equipment, access equipment, mobile communications, microwave communications, optical transmission, routers and other communication fields, automotive electronics, aerospace, etc.

To put it simply: the circuit board needs different voltage power supply, and the required voltage is not a power supply can be directly provided, generally need to use voltage conversion, if there are requirements for the board as a whole (such as: stability, reliability, etc.) to consider replacing the voltage conversion circuit with the module power supply.

For example: instrumentation, special equipment, electronic systems, high-reliability circuit equipment. Car radios and much more.

There is nothing that must be used, for example, a lighter needs to use gas, but it can also be replaced by oil. The power module can also be completely replaced by other things such as circuit regulation, the application range of the power module is very wide, but some people are willing to use the same product, some people are not willing to use, there is no necessity.

You can ask which departments will use these modules, or which manufacturers will buy them, or where or what industry these modules are generally sold to!

Hello! Generally used in instrumentation, special equipment, electronic systems, high-reliability circuit equipment, car radios and so on!

What exactly does your electronics factory do, there are a lot of such kinds. The more commonly used are multimeters, oscilloscopes, power meters, frequency meters and other test instruments; High-power power supply, low-power power supply, switching power supply, signal generator, AC and DC voltage and current fixed-point output instrument and other signal sources. There are many variety.

There are many of these, and the ammeter and voltmeter used for measuring current and voltage will be used, and the voltmeter will be used for current-related, such as on-site calibrator ......

For such a mold Qingyin high block, it depends on whether you are doing research and development, or used in the inspection of the famous ruler factory. In fact, there is not much difference between the two, mainly in the research and development will pay attention to the harmonics, and the reproduction is to test the load power. We also use it for R&D and factory inspection.

ZLG Zhiyuan Electronics' PA310, these two tests can be completed, the technical indicators can be met, you can participate in the cavity test.

There are too many of these, from instruments and equipment, to household appliances, small household appliances, to communication electronic equipment.

Basically, in general, wherever there is a need for electrical parameter conversion (such as voltage conversion, current conversion) on the PCB board, it is possible to use it. The most commonly used are in switching equipment, communication equipment, microwave equipment, routers, etc.

Module power supplies are widely used in switching equipment, access equipment, mobile communications, microwave communications, optical transmission, routers and other communication fields, automotive electronics, aerospace, etc.

Features of the module power supply:

1. Simple design. All you need is a power module with a small number of discrete components to get power. Shorten the development cycle.

Module power supplies generally have a variety of input and output options. Users can also repeatedly superimpose or cross-stack to form a building block combination power supply to achieve multiple inputs and outputs, which greatly reduces the prototype development time.

2. Flexible change. If the product design needs to be changed, simply convert or parallel another suitable power module.

3. Low technical requirements. Modular power supplies are typically equipped with standardized front-ends, highly integrated power modules, and other components, thus simplifying power supply design.

4. The module power supply shell has a trinity structure of heat sink, radiator and shell, which realizes the conduction cooling mode of the module power supply and makes the temperature value of the power supply close to the minimum value. At the same time, it gives the module power supply a standardized package.

5. High quality and reliable. Modular power supplies are generally fully automated and equipped with high-tech production technology, so the quality is stable and reliable.

6. Wide range of uses: Modular power supply can be widely used in aerospace, locomotives and ships, military weapons, power generation and distribution, post and telecommunications, metallurgical mines, automatic control, household appliances, instrumentation and scientific research experiments and other fields of social production and life, especially in the field of high reliability and high technology plays an irreplaceable and important role.

Note: The loss of high-power module switching power supply mainly includes four parts: high-frequency switching loss, high-frequency transformer loss, rectifier loss and line conduction loss. The lower the output voltage, the larger the output current, the greater the proportion of the rectification loss and line conduction loss in the total loss of the module switching power supply.

voltmeter, ammeter, millivoltmeter; Voltage regulators, load resistors.

Test index: input voltage adaptation range, ripple coefficient under rated output current, output voltage fluctuation range under rated current.
