How to Enhance Sound Quality with Audio Transformers

Posted by Bill Dull | December 7, 2023 | 0 Comments

At their most basic level, transformers consist of a primary and secondary winding situated around a magnetic core. Audio transformers are used to transmit sound signals from the primary to secondary winding with high accuracy and minimal distortion. Transformers are the most effective solution in many audio applications as they allow for electrical energy to be transferred from one circuit to [...]

Inherently vs. Non-Inherently Limited Transformers

Posted by Bill Dull | December 7, 2023 | 0 Comments

Transformers are passive electrical devices that use magnetic induction to step up or step down incoming AC power voltage to match the voltage needed for the user’s electronic device. They are organized into classifications based on capability and performance level. Class 2 transformers are used for low-voltage circuit control, while Class 3 transformers are used in mid-voltage control [...]

How Does Temperature Influence the Lifespan of a Transformer?

Posted by Bill Dull | December 18, 2021 | 0 Comments

All electrical devices produce heat as an operational byproduct. In transformers, normal operation causes an internal temperature increase or temperature rise. When the transformer is at its nameplate rating, the transformer temperature rise is the average temperature increase of the windings above the ambient temperature. This increase in temperature has the potential to shorten the [...]
