Eagle Enterprise - HLBB-140-0003 - B04202F1 - Encapsulated Toroid Transformer 140VA

Eaglerise Electric – Encapsulated Toroidal Transformer HLBB-140-0003 - B04202F1 – 140VA This toroidal transformer has heavier gauge wires than the normal requirement to avoid the copper lost during the full load output and over load output. Some advantages of toroidal transformers are higher efficiency, inherent EMI shielding, minimal signal distortion, more compact construction, low mechanical humming, low heat, and small off-load losses. Its disadvantages are more expensive construction, limitations on multi-phase systems, and higher inrush current. By reducing loss compared to EI transformers with fewer gaps and tighter windings, toroidal transformers have less vibration, or hum, that impact sound quality. Toroidal transformers are also designed to minimize core magnetization.

Weight: 6 lbs Leads 300mm, 67mm Insulated Sleeving A toroidal transformer is a type of electrical transformer constructed with a torus or donut-shaped core. Its primary and secondary windings are wound across the entire surface of the torus core, separated by an insulating material. This configuration minimizes the magnetic flux leakage. Therefore, a toroidal core is regarded as the ideal transformer core design. Advantages of toroidal transformers are higher efficiency, inherent EMI shielding, minimal signal distortion, more compact construction, low mechanical humming, low heat, and small off-load losses. Toroid transformers have higher efficiency than other transformers, typically around 95 to 99%. This can be attributed to its near-ideal design, which perfectly contains the magnetic flux inside the windings. Thus, there is no leakage flux. Since the magnetic flux is highly concentrated inside the coil windings and the windings are evenly distributed to the whole toroid core, the magnetic flux is efficiently utilized to couple the primary and secondary windings. Toroidal transformers are suitable for sensitive and critical electronic circuits because of several advantages over traditional square and rectangular-shaped transformers. Some of these advantages are high efficiency, quiet operation, minimal heat generation, and compact size. They are mostly seen in power supply systems, audio systems, control equipment, power inverters, and other electronic devices. Applications: Toroidal inductors and transformers are used in a wide range of electronic circuits: Power Generation, Transmission & Distribution, Lighting, Audio Systems, Electronic Equipment, Power Supplies, Inverters, and Amplifiers, which in turn are used in the vast majority of electrical equipment: TVs, radios, computers, and audio systems.
