eupen electrical components are a new type of contactless switching device composed entirely of solid-state electronic components. It utilizes the switching characteristics of electronic components (such as switching transistors, triacs, and other semiconductor devices) to achieve contactless, spark-free circuit connection and disconnection, hence it is also known as a "contactless switch." A solid-state relay is a four-terminal active device, where two terminals are input control terminals and the other two are output controlled terminals. It has both amplification drive and isolation functions, making it very suitable for driving high-power switching actuators. Compared to electromagnetic relays, it offers higher reliability, is contactless, has a long service life, fast speed, and low external interference, and has been widely applied [1].

eupen electrical component features

1. High sensitivity; 2. Geometric shape has multi-faceted adaptability, allowing fiber optic sensors to be made in any shape; 3. Can manufacture devices that sense various physical information (sound, magnetism, temperature, rotation, etc.); 4. Can be used in high voltage, electrical noise, high temperature, corrosion, or other harsh environments; 14. And has inherent compatibility with fiber optic telemetry technology. The advantages of fiber optic sensors compared to traditional sensors are that they use light as the carrier of sensitive information and optical fiber as the medium for transmitting sensitive information, possessing the characteristics of optical fiber and optical measurement, with a series of unique advantages. Good electrical insulation performance, strong anti-electromagnetic interference ability, non-invasive, high sensitivity, easy to realize remote monitoring of measured signals, corrosion resistance, explosion-proof, flexible optical path, and easy connection to computers. Sensors are developing towards sensitivity, precision, strong adaptability, compactness, and intelligence. They can serve as human eyes and ears in places inaccessible to humans (such as high-temperature areas or areas harmful to humans, such as nuclear radiation zones), and can even surpass human physiological limits, receiving external information imperceptible to human senses.

eupen electrical component structure

The rated current of the fuse element is not equal to the rated current of the fuse. The rated current of the fuse element is selected based on the load current of the protected equipment. The rated current of the fuse should be greater than the rated current of the fuse element and determined in coordination with the main electrical appliance. The fuse mainly consists of 12 parts: the fuse element, the housing, and the support. The fuse element is the key component controlling the fusing characteristics. The material, size, and shape of the fuse element determine the fusing characteristics. Fuse element materials are divided into two categories: low melting point and high melting point. Low melting point materials, such as lead and lead alloys, have a low melting point and fuse easily. Due to their higher resistivity, the cross-sectional size of the fuse element is larger, generating more metal vapor during fusing, making them suitable only for fuses with low breaking capacity. High melting point materials, such as copper and silver, have a high melting point and do not fuse easily. However, due to their lower resistivity, they can be made with a smaller cross-sectional size than low melting point fuse elements, generating less metal vapor during fusing, making them suitable for fuses with high breaking capacity. The shape of the fuse element is divided into wire-shaped and strip-shaped. Changing the shape of the variable cross-section can significantly alter the fusing characteristics of the fuse. Fuses have various different fusing characteristic curves, suitable for the needs of different types of protected objects.

The simplest switch has two pieces of metal called "contacts." When the two contacts touch, they form a current loop; when they do not touch, the current circuit is open. When selecting contact metals, consideration must be given to their corrosion resistance, as most metals form insulating oxides after oxidation, preventing the contacts from working properly. Selection of contact metals also requires consideration of factors such as electrical conductivity, hardness, mechanical strength, cost, and toxicity. Sometimes, corrosion-resistant metals are plated onto the contacts. Plating is generally applied to the contact surface to avoid performance degradation due to oxides. Sometimes, non-metallic conductive materials, such as conductive plastics, are used for the contact surface. In addition to contacts, switches have movable parts that make the contacts conductive or non-conductive. Switches can be classified into toggle switches, push-button switches, rocker switches, etc., based on the different movable parts, and the movable parts can also be other types of mechanical linkages.
