In December 2020, product safety standards based on IEC 62368-1 will be superseding IEC 60950 and 60065 across the world, including Underwriters Laboratories (UL) in the US. The goal of the new standard is to establish a more universal and clear approach to hazard-based product testing. It replaces two previous standards—60065 for audio/visual (AV) equipment and 60950-1 for information [...]
Underwriters Laboratories (UL) is a globally recognized standards company that works to establish safety guidelines and industry standards for the design, production, and marketing of a wide variety of products and components worldwide, with a particular focus on products manufactured and disseminated in North America. UL is dedicated to the development of more secure and sustainable products [...]
In China, one of the most important national events is the Spring Festival. This annual event—also often referred to as Chinese New Year—falls somewhere between the end of January and the middle of February. In 2021, it is set to begin on February 12th.
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 [...]
When sourcing a standard or custom transformer, it is essential to choose a quality manufacturer to ensure the product functions as intended. However, given the large number of potential options available, selecting the right one can be challenging. In the following blog post, we provide an overview of some of the key factors to consider when vetting transformer manufacturers to help you choose [...]
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.
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:
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.
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 [...]
