Are you in the market looking for power modules? In addition to many other factors, you will also have to consider choosing between custom vs off-the-shelf power modules. While both are power modules that are designed to execute various power-related functions in devices and applications, they are different in many ways. Before you make a final decision on which one to buy, it is important to have full information on each type of power model. Between custom vs off-shelf power modules, which one should I choose?  Given the importance of power modules in all electronic applications, you won't wish to make any mistake when it comes to choosing your preferred module.

In this article, we are going to break down the differences between custom and off-the-shelf power modules.  We will also guide you on what you should look at when it comes to choosing between these two power modules.

What is a custom power module?

A custom power module has been designed and manufactured to meet the specific needs of an application. During the manufacturing process, a business or organization will give a manufacturer a list of its requirements related to the power module. From there, the manufacturer will ensure that the final product meets all these requirements. Let’s say a manufacturer needs more power output from the module yet most modules in the market have lower power ratings. Going for the custom power module will be the best option.

Custom power modules are produced by manufacturers who have immense knowledge and experience in the field of electronics. They should be able to take t customer requirements and then implement the project without any difficulties. 

What are off-the-shelf power modules?

Off-the-shelf power modules are ready-made modules that are mass-produced to meet the needs of a wide market. These modules are used in different application areas. They are not just for specific devices and applications. This explains why they are mass-produced as they are needed by many people. It is the responsibility of buyers to confirm the specifications of these power modules so that they can decide whether they are suitable for their applications. This is a complete reverse for the custom modules where manufacturers are required to build products according to the specifications of the buyers.

Pros of custom power modules

Here are some of the benefits or advantages of custom-made power modules:

· Perfect for your business and application: The fact that custom power modules are made according to the specific needs of their application domains means that they are a perfect solution for your needs. You will not have to make any modifications to the module or the device.

· Optimized performance: One reason for the customization is to get the best performance from the module.  When compared to the stock power modules, you are likely to get the best performance from the custom power modules.

· Low running cost: Even though the initial cost of custom power modules is high, you are likely to enjoy the long-term benefits related to the cost of the modules. Customization helps to create a perfect match between the module and the application. This minimizes cases of constant damage due to a mismatch. The result is the long lifespan of the module.

· High safety levels: Custom power modules are considered the safest bet mainly because of the perfect match between the modules and the application. Power is one of the requirements that manufacturers consider when customizing the modules.  By getting an ideal balance and match, you will avoid incidences of overcurrent and overvoltage in the power module.

· Highly scalable: Custom power modules are designed not only to address the current problems but also to solve the issues that may arise shortly. For example, in case you want to add more power to the module, it is easy to do so when it is c already customized to meet the specific needs of your application.

· Easy to modify: Other than being scalable, custom power modules are easy to modify. Since they are designed according to your needs, you can easily add some features and change some elements on the modules. 

Cons of custom power modules

· Expensive: Custom power modules are costlier than the stock power modules. This mainly stems from the production process that is involved in producing these modules. Adding unique features to meet the needs of a specific application is an expensive process.

· Longer production time:  It is rare for one to order custom power modules straight from the manufacturer and get immediate delivery. Manufacturers have to consider all the features and requirements of the module before they embark on the production and finally delivery of the product. The period can be longer in case of a communication breakdown between the two parties.

· Overdependence on custom module manufacturers: Very few manufacturers can produce custom power modules. This means that you will be at the mercy of a few manufacturers. Limited freedom can be detrimental to the whole production pipeline. In case of a disruption in the company, you will have to wait for long since finding an alternative manufacturer will be a difficult task to accomplish. Dependence extends even after the product has been delivered as you will still be depending on the manufacturer when it comes to s repairing and servicing the power module.

· Requires close monitoring and communication: With custom-made power modules, you will need to work closely with the manufacturer. This should start from the design to the completion of the product. This is done to ensure that you have exactly what you requested from the manufacturer.

Pros of Off-the-shelf power modules

· Easily available: Off-the-shelf modules are widely available in the electronics market. You don’t have to make a special order or request. Just contact your distributor and you will be able to find the right power module that you need.

· Cost-friendly: Comparatively, off-the-shelf power modules are cheaper than the custom modules. Mass production makes it easy for the manufacturers to attach reasonable price tags on these modules. No special features and requirements are added to these modules hence the low prices.

· Cheap to maintain: Closely related to the buying price is the maintenance cost. Off-the-shelf power modules have low maintenance costs.  Their spare parts are easily available at low costs. In case of damages and breakages, you can easily replace them. Additionally, they don’t require high levels of expertise to handle and use.

· Large community support: With off-the-shelf power modules, you will enjoy the benefits that come with having a large community support. The fact that many people have bought these modules means that you can easily seek help from other users when the need arises.

Limitations of off-the-shelf power modules

· May not be perfect for your application needs:  In as much as the power module may be functional and operational, it may not be the perfect solution for your application.  This means that the performance and efficiency of this module may not be up to the standards that you expected.

· Difficult to modify: Would you like to introduce some changes to the power module? It isn't easy to do so on off-the-shelf power modules. You are forced to be contented with the features of the module in its stock form.

· Compatibility issues:  Cases of incompatibility are quite rampant when dealing with off-the-shelf power modules. If this happens, you may end up losing the money and even slowing the production.

Custom vs off-the-shelf power modules: Which one should I choose?

After comparing these two types of power modules, which one should I choose? Simply compare the pros and cons that we have listed and you will be able to know which one to choose. You can also use key pointers that determine your selection of the power module.

Are you looking for a scalable, efficient, and high-performance power module? It would help if you considered choosing custom power modules. However, you should be ready to part with the higher cost. If you are not keen on any specific features or performance, then buy off-the-shelf power modules. 

Conclusion

I hope that with this guide, you will be in a perfect position to make the final choice between custom vs off-the-shelf power modules. It takes a lot of thought and deliberation to make the final choice. Just keep in mind that your needs and requirements will always take the stage in deciding the type of power module that you should choose.
