Is An EI Transformer A Good Choice For You? – Miracle Electronics

With every transformer performing the same task of trading voltage for current in a circuit, without affecting the total electrical power, different types of transformers work differently to achieving the same goal. Also, different types in regards to the shape, size, material, etc. also affects the quality of performance. In this blog today, we’ll speak about one particular kind of transformer – the EI transformer.

What is EI transformer?

As the name itself suggests, EI transformer is one whose core is combined by laminations shaped “E” and “I”. A traditional and economical transformer, the EI transformer is widely used in a variety of electronic equipment and audio applications. The air gap between the E and I laminations can be easily adjusted by filling it with a suitable medium, making it suitable for building output transformers and chokes. This is the reason why many audio output transformers and chokes are designed with the EI transformer.

Why should you opt for an EI transformer?

EI transformers have a very simple structure, making it absolutely easy to manufacture, which is why most transformer factories are able to manufacture these transformers.

It is very easy to find the components required to build an EI transformer in the market, making it an easy-make as well as economical solution. With everything being available easily, the prices automatically go down.

EI cores are flat stampings with no need of any kind of bending or forming, which makes it very economical to manufacture.

The laminations can be removed from a single rectangular sheet without substantial wastage.

The mounting method of the EI transformer is simple.

EI transformer cores are more preferred than other U, C, and L core types, mainly because more surface space is protected by the winding in these cores.

The make of an IE transformer is such that the whole thing can be held together conveniently with simple corner fixings, or just vacuum impregnation with lacquer.

There is very good magnetic coupling between the two ends of the core.

Are there any disadvantages of using an EI transformer?

Just like anything else, EI transformers, in spite of having so many good qualities, also have drawbacks. One major drawback is that these cores don’t have self-shielding quality in them.

After going through the blog, it’s time you decide as to whether you would want to use an EI transformer for your application or not. Despite the fact that an EI transformer doesn’t have self-shielding, there are so many other benefits associated with it. So, whether it is for differential, power, or telecom inductors, converters, or inverter transformers, if EI seems to be the right choice for you, you could approach Miracle Electronics for the same. They’re the most reliable EI transformer manufacturer in India, where you can get durable and highly efficient transformers that come with superior wiring, varnishing, and connection terminators, all of which provide excellent regulation with minimal temperature rise. You can thus make the most of your electrical devices by buying such RoHS and REACH compliant EI transformers that can lower the voltage exactly to a value that is required by your appliance, while keeping it running right and safe.

 

When Building Electronic Box Assemblies – Miracle Electronics

An electronic box assembly is an electromechanical assembly process that includes enclosure fabrication, installation of sub-assemblies and components, and routing of wires and harnesses. It could mean anything from a PCB assembly in a cabinet fill or wires, or a complex fully integrated electromechanical system with pneumatics and electronics. 

Whatever it may be, you need to have your components placed in a project box that protects, as well as makes your product truly useful and accessible.

Designing electronic box assemblies in India presents its own challenges, which is why you need a manufacturer who goes ahead with the right approach. You need one who specializes in the capability you want to build, and has experience in building the particular product and components you’re looking for. Outsourcing your electronic box assembly is an easy task when you have such a reliable manufacture partnered with. But, while you outsource, you also need to consider a few basics to help the build process go smoothly. There are certain instructions you need to send to the manufacturer for building the box appropriately. These include –

Bill of Materials (BOM)

The Bill of Materials gives the manufacturer an idea of all the key components, with a clear mention about the materials that you will be providing, and those to be sourced by the manufacturer. You may also define every tiny detail like the adhesives, tie wraps, nuts and bolts, washers, heat shrink, etc. if you wish to avoid even the smallest confusion or misconceptions in the future. You should also clearly specify the tolerances and finish of each component if you want anything particular to be considered. All in all, it is best to specify every minute detail just exactly how you need it. If you’re too confused as to what materials or specifications should be used for your particular requirement, you can also communicate all your ideas and purposes to the manufacturer, and help him decide the best solution for you.

Assembling

Once all the materials and components are decided and discussed upon, along with all the specifications and details mentioned, it’s now time to move on to the process of assembling them. if possible, you can provide a 3D CAD model to help the manufacturer visualize the final product like you want it to be. Or, at the least, you must provide the assembly drawings with every detail clearly mentioned. However, if you’re not too sure, you can always define the purpose and requirement, and leave the job of designing and prototyping to the manufacturer. This can also help when there are large amounts of space, labour, and specialist tools required for the build.

Testing

Testing is always an integral part for any product, especially when it is an electronic or electrical device. The basic electrical safety testing, such as earth bond and flash tests, need to be conducted, thus specified well in advance. Other tests may include visual inspection, functional testing, factory acceptance testing, etc., depending upon your specific product. If you’re not too sure again, your manufacturer can help decide as to what kind of testing is important, as they will have the proper knowledge and experience of what will work best for your particular product.

Outsourcing and electronic box assembly inevitable requires close cooperation between the client and manufacturer. By providing all the above information, and every other detail possible, there would be lesser confusion, lesser misunderstandings, and lesser wastage of time and money. Whether you require a simple box build assembly, or complex electronic box assemblies in India, you can get in touch with Miracle Electronics to ensure that your product is protected and looks good with the final assemble that proves to be a true reflection of your encased product. Dedicated to lean manufacturing techniques, Miracle Electronics will always offer maximized efficiency and a complete package, no matter what the product may be.
