SMD ED8*11-4H Fully Encapsulated Low Frequency Transformer For Audio Equipment

1.Product Description

The ED8 fully sealed low-frequency transformer is carefully designed for low-frequency application scenarios. ED8 "indicates its specific specification parameters, which determine the physical dimensions and basic electromagnetic characteristics of the transformer. The fully sealed design is one of its highlights, which not only effectively resists the invasion of external moisture, dust, and corrosive substances, prolongs its service life, but also greatly reduces the leakage of electromagnetic interference, ensuring that sensitive electronic components around are not affected. This transformer focuses on the low-frequency field, and its operating frequency range is usually set between tens of hertz and hundreds of hertz. In this frequency band, it can demonstrate excellent performance, efficiently perform voltage conversion, current regulation, and circuit isolation. With its excellent voltage conversion ratio, it can accurately adjust the input AC voltage to the specific voltage values required by various devices. Widely used in audio equipment, industrial control, instrumentation and other fields, providing reliable electromagnetic support for the stable operation and signal processing of equipment in these fields.

2.Performance Characteristics

The ED8 fully sealed low-frequency transformer has the following characteristics:
1. Excellent sealing performance: Adopting a fully sealed structure, such as welding the box cover and edge, the oil and insulation materials inside the transformer are completely isolated from the external atmosphere, which can effectively prevent and slow down the moisture and deterioration of the transformer oil and insulation materials.

2. Good stability: Special anti loosening and fastening measures are taken internally, and high-quality oil resistant materials and double sealing structures are selected to ensure that the structural components of the transformer do not loosen during long-distance transportation and operation, and the operation is reliable.

3.Maintenance free or low maintenance requirements: The oil storage tank has been eliminated and an expansion type radiator has been adopted, which can expand and contract with the volume of transformer oil, effectively regulating the pressure and oil level inside the oil tank. This achieves internal maintenance free and minimal external maintenance.

4.Higher safety: Equipped with a pressure relief valve, when the transformer overload or fault causes the internal pressure of the oil tank to reach a certain value, the pressure relief valve will operate to reliably release the pressure. When the pressure decreases to the normal value, it will return to its original state.

5. Low electromagnetic interference: The fully sealed structure helps reduce electromagnetic interference leakage, and usually uses high permeability silicon steel sheets as the iron core, which can make the magnetic field more concentrated and further reduce electromagnetic interference to the outside world.

6. Stable electrical performance: The working frequency is generally between tens of hertz and several thousand hertz, and it can stably perform voltage conversion, current regulation, and circuit isolation in the low frequency range. The voltage conversion ratio is stable, and the input AC voltage can be accurately adjusted to the specific voltage required by the equipment.

7. Small size and light weight: Compared to traditional low-frequency transformers, ED8 fully sealed low-frequency transformers are designed to be more compact, using efficient iron core materials and reasonable winding structures. While meeting electrical performance requirements, they have a smaller volume and lighter weight, making them easy to install and use.

8. Good insulation performance: The internal insulation design is well-designed. In addition to the insulation measures of the winding itself, the fully sealed structure also provides a better environment for insulation, reducing the risk of insulation performance degradation caused by external factors. It can effectively prevent internal short circuits and other faults, ensuring the safe operation of the transformer.
