EI19 Horizontal Low Frequency Transformer Hard Feet 2+2 For Industrial Control

1.Product Description

The EI19 Horizontal Low Frequency Transformer is composed of multiple parts, which together determine its structure and function. The following is a specific introduction:
----Structure and composition:
1. Magnetic core: The magnetic core of EI19 horizontal low-frequency transformer is composed of E-type and I-type magnetic sheets, usually made of silicon steel sheet material. Silicon steel sheets have high magnetic permeability and low hysteresis loss, which can effectively conduct magnetism. The E-type and I-type magnetic plates are alternately stacked to form a closed magnetic circuit, providing a good magnetic medium for the electromagnetic induction of transformers. EI19 represents the size specification of the magnetic core, where "19" generally refers to the width of the core column being 19 millimeters. Different sizes will affect the performance parameters such as power capacity of the transformer.

2. Winding:
Primary winding: It is the part of the transformer connected to the power supply, usually wound with enameled wire on one side of the magnetic core. The number of turns of the primary winding is determined based on the input voltage and the transformer's transformation ratio requirements, while its wire diameter depends on the current passing through it. For example, when the input voltage is high, the number of turns in the primary winding will correspondingly increase to meet the requirements of the transformation ratio.

Secondary winding: connected to the load, also made of enameled wire winding, multiple secondary windings can be designed as needed to provide different output voltages. The number of turns and wire diameter of the secondary winding are determined according to the requirements of the load. The number of turns determines the magnitude of the output voltage, while the wire diameter determines the magnitude of the current that can be output. Multiple secondary windings can meet the different voltage requirements of different circuits, such as providing suitable operating voltages for different chips and modules in electronic devices.

3. Skeleton: Skeleton is used to support and fix windings, usually made of insulating materials such as plastic. It fixes the winding on the magnetic core to ensure that the winding does not shift during operation, and also serves as insulation to prevent short circuits between the winding and the magnetic core, as well as between different windings.

4. Pin: Pin is the part of the transformer that connects to the external circuit, usually made of metal material and welded to the lead out end of the winding. Through pins, transformers can be easily connected to printed circuit boards (PCBs) or other circuits to achieve the transmission of electrical energy and signals.

2.Function

1. Voltage conversion: This is one of the main functions of the EI19 horizontal low-frequency transformer. According to the principle of electromagnetic induction, when alternating current passes through the primary winding, an alternating magnetic field is generated in the magnetic core, which is coupled to the secondary winding through the magnetic core, thereby inducing a corresponding voltage in the secondary winding. By adjusting the turns ratio of the primary winding and secondary winding, different voltage transformations can be achieved to increase or decrease the input voltage to the desired output voltage, meeting the voltage requirements of different loads.

2. Electrical isolation: EI19 horizontal low-frequency transformer can achieve electrical isolation between primary and secondary circuits. Due to the lack of direct electrical connection between the primary and secondary windings, energy is only transmitted through magnetic coupling, effectively preventing electrical interference, overvoltage, and other issues in the primary circuit from affecting the secondary circuit, thereby improving the safety and reliability of the circuit. This function is particularly important in situations where electrical isolation is required, such as medical equipment, industrial control equipment, etc.

3. Power transmission: It can transfer the power of the power supply to the load. In the process of power transmission, transformers transfer the electrical energy from the primary winding to the secondary winding through electromagnetic induction, providing the required power for the load. By designing the parameters such as wire diameter and number of turns of the winding reasonably, it can ensure that the transformer has high efficiency in transmitting power and reduce energy loss.

4. Filtering function: In some circuits, the EI19 horizontal low-frequency transformer can also play a certain filtering role. Due to the inductance of the transformer winding, it has a high impedance for high-frequency components in AC signals, which can suppress high-frequency noise and interference signals, thereby making the output voltage more stable and pure, and providing a better working environment for the load.
