Turnkey PCB Services – What Is It All About?


Miracle Electronics  is the most reliable and versatile PCB assembly manufacturer in India who offers end-to-end “turnkey” solutions in manufacturing of the best PCB assembly from Germany. Now, what does that mean? When you search the Web for the meaning of “turnkey”, you will find it defined as “of or involving the provision of a complete product or service that is ready for immediate use”. So, when we speak about turnkey PCB solutions, we mean the production of a complete PCB product, right from planning and designing to the manufacturing and testing phases.

Power Transformers Versus Distribution Transformers


Power transformers are high voltage transformers that are installed at various power stations for power generation and transmission. They could either be step-up or step-down, depending upon whether your application requires to increase or decrease the incoming power. Distribution transformers are, on the other hand, those transformers that step down the voltage and current level of a transmission line, according to the level already set.

High-Speed PCBs – Challenges And Designing Considerations


With the immense dependence seen on electrical and electronic appliances today, and with every such appliance becoming smaller than its general size, there is an increasing need for small and smart circuit boards too that can hold together a multitude of elements compatibly into a tiny space. In addition, people are also getting very impatient with the lack of time they have. Thus, they demand every appliance to work at the fastest possible speed, not having them to wait for even a second. With such flash-like demands, PCBs also need to be high-speed ones. And, all of this combined, it becomes even more challenging to build such complicated, complex, tiny, and high-speed PCBs that are also high on performance. Thus, it becomes crucial to pay complete focused attention to manufacturing such PCBs. Listed below are some of the most important factors to consider when building a PCB assembly from India.

When Buying A Transformer – Things To Consider


Transformers are versatile electrical equipment used to transfer electrical energy between two or more circuits. A varying current in one coil produces a varying magnetic flux, which induces a varying electromotive force across the second coil wound around the same core. Thus, with the help of a transformer, electrical energy can be transferred between the two coils, without having a metallic connection between the circuits. Transformers have found their usage in all kinds of industries like industrial, commercial, aerospace, medical, electronics, audio, and more. In fact, they are also used in domestic and residential applications. All in all, transformers are a vital part of almost every electric and electronic appliance. Transformers have thus made our lives very easy and simple.

Benefits of isolation transformers


Isolation transformers, like every other kind of transformer, is used to transfer electric power from an alternating current power source to a device, with the difference being that in this case, the powered-up device will be isolated from the power source for safety reasons. With this setup, not only is the device kept safe, but the operators assigned to handle and manage the operations are also protected against possible accidents and hazards. The main principle on which isolation transformers work is isolating the various sections of electrical systems in order to halt the flow of current, with no direct path of conduction. However, energy is still exchanged between various sections via electromagnetic waves, induction, or capacitance. All in all, isolation transformers keep blocking DC signal transmission from one circuit to another, while allowing AC components to pass by.

Different Transformers Use Different Windings


Transformers are static electrical devices that transfer AC electric power from one circuit to another at a constant frequency, while increasing or decreasing the voltage, as required by the equipment. The process that helps such transfer is electromagnetic induction.

How Can You Reduce Transformer Noise?


Electrical transformers are always heard to be making humming and buzzing sounds, which can be very frustrating and disturbing. The reason for this noise is the process of magnetostriction that goes on within the transformer, in which a magnetic steel sheet changes it dimensions and shape when magnetized. Because magnetostriction is an important process of a transformer, the noise cannot be completely eliminated. But yes, if desired, it can be reduced to a certain extent.

Medical Isolation Transformers By Miracle Electronics


Almost everything that we use today is automated and works on power. The things that we depend on everyday – smartphones, laptops, televisions, refrigerators, microwave ovens, lights, fans, air conditioners, geysers – all require power to run. Without these appliances, life is almost impossible; and without power, the working of these appliances is impossible. Thus, power transfer is very important for us today. Let alone these everyday appliances, even the systems in medical facilities are now automated and require power. Every big and small appliance in hospitals and clinics works on power supplied to them. Thus, without power, we would not be able to even get the best medical facilities that we have access to today!

Being Safe While Working With Transformers


As much as transformers are important to us in our daily lives, by providing us with safe amounts of current and electricity to run our electric and electronic appliances, they can be equally hazardous if not used properly. This is why it is important to undertake certain safety measures while operating your transformers, or during its regular maintenance or repair procedures. Any carelessness may lead to shocks, or even death. In addition, it may lead to errors, which even if minute, may damage the entire transformer, which may further result in failure of the appliance too. You definitely don’t want any of this to happen, which is why you need to take up these safety measures for sure.

How To Find The Right Common Mode Choke?


Inductors are passive two-terminal electrical components that store energy in a magnetic field, when electric current flows through them. They generally consist of an insulated wire wound into a coil, around a core. Common mode chokes work as passive electronic inductors that filter out frequencies. High frequencies are specifically eliminated, while allowing low frequencies in an electronic system. With such properties, they have proven to be really helpful when used in electrical transformers
