How To Select A Transformer

Many of our designs are industry standards with cross referencing to other manufacturers’ part numbers. If you are starting with a new application and want to know how to select a transformer, here are the things you need to decide to make your choice.

Input & Output Voltage(s), Frequency, Current.

To select the proper transformer, determine the input and output voltages, frequency and current. The faster the voltage changes, the higher the frequency. The higher the current, the more heat is produced. Other equations apply.

Safety Agency Certification Requirements.

UL, CSA, CE requirements vary from one application to another. For example, medical products have very different requirements than office products. You should determine which specific agency standard you are trying to meet.

Mounting Configuration needs to be decided.

Usual choices are PC mount or Chassis mount. However, our application engineers can offer a number of other options to meet your special requirements.

Available area is sometimes very limited.

If this is true in your configuration be ready to specify Height, Length, & Width limits. Knowing size limitations up front will help expedite the proper transformer selection process.

Number of configurations Vs’s cost & inventory goals deserves some thought.

We are ready to help you select the best product whether it is a standard catalog design or a custom design. For custom designs, we often use our modified versions of our standard line to ensure ready availability and minimum cost.

MCI’s experienced design engineers are ready to discuss all of the above issues to help you select the best product whether it be a standard catalog design or a custom design to fulfill your application’s goals. If you need a custom design we do our best to utilize components that are used in our standard line to ensure ready availability and minimum cost .
