How Does Quality Assurance Impact the Cost of a Transformer?

Posted by Bill Dull | April 7, 2020 | 0 Comments

Many customers believe that the cost of a transformer is limited to the amount that they pay upfront. At a basic level, transformer costs are determined by the time and materials used during the manufacturing process. However, the truth is that transformer costs are impacted by numerous complex factors, particularly when considering the impact on the overall system. 


An Introduction to Common Mode Chokes

Posted by Bill Dull | February 28, 2020 | 0 Comments

A choke is a magnetic inductor used to block or limit unwanted high-frequency alternating current (AC) while allowing the desired lower frequency direct current (DC) to pass through. The choke acts as a filter for the noise produced by other radio signaling devices, inverters, and unshielded equipment, thereby reducing interference in electrical and electronic devices and systems.

What Is An Audio Transformer? Audio transformers are electronic devices that transmit frequencies within the audio band. They are used in audio amplifier circuits to:


Food and Beverage Applications for Class 2/3 Power Transformers

Posted by Bill Dull | October 3, 2019 | 0 Comments

Transformers convert alternating current (AC) from one voltage to a higher or lower voltage. Class 2 transformers are safer, more highly-rated electrical components frequently used in the food and beverage industry. Class 2 is a compliance rating which signifies that the power transformer meets safety standards that reduce the risks of fire or shock.


Autotransformer Power Transformers

What is an Autotransformer?    Autotransformers feature a single winding wound onto a laminated core. They're similar to two-winding transformers, but their differences lie in the ways that the primary and secondary winding are interrelated. There are two varieties of autotransformers which may be differentiated by their construction. In the first type, the transformer relies on continuous [...]


Litz Wire vs. Copper Foil

Posted by Bill Dull | August 29, 2019 | 0 Comments

In our most recent blog, we introduced Litz wire and discussed its various uses and properties. Litz wire is a multi-strand wire used to conduct alternating current (AC) at radio frequencies. Individually insulated magnet wires are braided together in a pattern that helps reduce AC losses from skin effects and proximity effects found in high-frequency windings. In this blog, we’ll compare Litz [...]


What Is Litz Wire and Its Applications

Posted by Bill Dull | August 13, 2019 | 0 Comments

Our engineering team frequently receives questions about whether we use Litz wire in our designs. We decided to focus this blog on educating our clients on this subject and explain why Litz wire is so ideal for certain applications and industries. Using Litz wire is associated with a number of benefits, including:


What Are Electrical Transformers?

Posted by Bill Dull | July 29, 2019 | 0 Comments

Transformers are electrical devices with the capacity to change the voltage level of an alternating current (AC) in a circuit. They function only with AC circuits, not with direct current (DC) circuits. The basic components of a transformer are two separate coils of wire wound around a single core. The coil connected to the incoming or voltage source is the primary coil, the coil connected to [...]


Medical Applications for Power Transformers

Posted by Bill Dull | June 3, 2019 | 0 Comments

Complex electronics sometimes create stray electromagnetic fields, which can interfere with the performance of other electronics. This problem is especially prevalent in confined spaces like hospital rooms and surgery floors, and interference can be even more dangerous when it applies to delicate tools such as health monitoring equipment.
