ELEKTROSYSTEMTE electrical components Germany ELEKTROSYSTEMTE model ELEKTROSYSTEMTE price

ELEKTROSYSTEMTE electrical component is a high-power electrical component, also known as a thyristor. It has the advantages of small size, high efficiency, and long service life. In automatic control systems, it can serve as a high-power drive device, enabling low-power control elements to control high-power equipment. It is widely used in AC/DC motor speed control systems, power regulation systems, and servo systems. Thyristors are divided into unidirectional thyristors and bidirectional thyristors. Bidirectional thyristors are also called triac bidirectional thyristors, abbreviated as TRIAC. Structurally, a bidirectional thyristor is equivalent to two unidirectional thyristors connected in reverse parallel, providing bidirectional conduction capability. Its on/off state is determined by the gate G. Applying a positive pulse (or negative pulse) to the gate G enables forward (or reverse) conduction. The advantages of this device include a simple control circuit and no reverse voltage withstand issue, making it particularly suitable for use as an AC contactless switch.

ELEKTROSYSTEMTE electrical component features

A solid-state relay is a contactless electronic switch with isolation functionality. It has no mechanical contact parts during switching. Therefore, in addition to having the same functions as electromagnetic relays, solid-state relays offer logic circuit compatibility, vibration and mechanical shock resistance, unrestricted mounting positions, good moisture, mold, and corrosion resistance, and excellent performance in explosion-proofing and ozone pollution prevention. They feature low input power, high sensitivity, low control power, good electromagnetic compatibility, low noise, and high operating frequency. With no internal mechanical parts and a fully sealed potting structure, solid-state relays provide vibration resistance, corrosion resistance, long service life, and high reliability. AC solid-state relays use zero-crossing triggering technology, resulting in short switching times, making them suitable for higher-frequency applications. Optical isolation is used between the input and output circuits, resulting in very low input power consumption. The output terminal includes a protection circuit and strong load capacity.

ELEKTROSYSTEMTE electrical component function

In DC circuits, a capacitor acts as an open circuit. A capacitor is a component capable of storing electric charge and is one of the most commonly used electronic components. Starting with the structure of a capacitor: the simplest capacitor consists of two end plates and an insulating dielectric medium in between (including air). When energized, the plates become charged, creating a voltage (potential difference). However, due to the insulating material in between, the entire capacitor does not conduct electricity. This holds true provided the voltage does not exceed the capacitor's critical voltage (breakdown voltage). We know that any material is relatively insulating; when the voltage across a material increases to a certain level, the material becomes conductive. We call this voltage the breakdown voltage. Capacitors are no exception; once a capacitor breaks down, it is no longer an insulator. However, at the secondary school level, such voltages are not encountered in circuits, so capacitors operate below the breakdown voltage and can be regarded as insulators. However, in AC circuits, the direction of current changes over time according to a specific functional relationship. The charging and discharging process of a capacitor takes time, during which a changing electric field forms between the plates, and this electric field is also a function of time. In reality, current passes through the capacitor in the form of an electric field.

(1) Electron tubes can be classified according to their application into voltage amplifier tubes, power amplifier tubes, gas-filled tubes, thyratrons, ignitrons, frequency converter tubes, rectifier tubes, detector tubes, tuning indicator tubes (magic eye), voltage regulator tubes, etc. (2) Electron tubes can be classified according to the number of electrodes into voltage amplifier tubes, triodes, tetrodes, pentodes, hexodes, heptodes, octodes, nonodes, and composite tubes, etc. Tubes with more than three electrodes are also called multi-electrode tubes or multi-grid tubes. (3) Electron tubes can be classified according to their shape and envelope material into bottle-shaped glass tubes (ST tubes), "acorn" tubes, cylindrical glass tubes (GT tubes), large glass tubes (G type tubes), metal-ceramic tubes, miniature tubes (also called peanut tubes or finger-shaped tubes, MT tubes), lighthouse tubes (lighthouse tubes), subminiature tubes (pencil-shaped tubes), and other types. (4) Electron tubes can be classified according to their internal structure into single diodes, diodes, double-diode triodes, double diodes, single triodes, power pentodes, beam tetrodes, beam pentodes, dual diodes, diode-pentode composite tubes, beam tetrodes, triode-pentode composite tubes, triode-hexode composite tubes, triode-heptode composite tubes, beam power tubes, and other types. (5) Electron tubes can be classified according to the cathode heating method into directly heated cathode electron tubes (current passes directly through the cathode to bring it to thermionic emission state) and indirectly heated cathode electron tubes (the cathode is heated by a filament adjacent to the cathode). (6) Electron tubes can be classified according to the grid control characteristic into sharp-cutoff electron tubes and remote-cutoff electron tubes. (7) Electron tubes can be classified according to the cooling method into water-cooled electron tubes, air-cooled electron tubes, and natural convection-cooled electron tubes.
