ACCUTECHNOLOGY electrical components, German ACCUTECHNOLOGY models, ACCUTECHNOLOGY prices

ACCUTECHNOLOGY electrical components are indispensable measuring instruments for departments such as power electronics, generally aimed at measuring voltage, current, and resistance. Multimeters are classified into analog multimeters and digital multimeters based on their display method. They are multifunctional, multi-range measuring instruments. Generally, multimeters can measure DC current, DC voltage, AC current, AC voltage, resistance, and audio levels; some can also measure AC current, capacitance, inductance, and certain semiconductor parameters (such as β). A multimeter is a moving-coil instrument with a rectifier that can measure various electrical parameters such as AC/DC current, voltage, and resistance. For each electrical quantity, there are generally several ranges. Also known as a multitester or simply tester. A multimeter consists of a moving-coil ammeter (meter head), measuring circuits, and a selector switch. By changing the selector switch, various electrical parameters can be measured conveniently. The main basis for its circuit calculation is Ohm's law for closed circuits. There are many types of multimeters, which should be selected according to different requirements during use.

ACCUTECHNOLOGY electrical component applications

The basic circuits of analog integrated circuits include current sources, single-stage amplifiers, filters, feedback circuits, and current mirror circuits. Higher-level basic circuits composed of these include operational amplifiers and comparators, while even higher-level circuits include switched-capacitor circuits, phase-locked loops, and ADC/DAC. Based on the response relationship between output and input signals, analog integrated circuits can be divided into two categories: linear integrated circuits and nonlinear integrated circuits. The response between the output and input signals of the former is usually linear; the shape of the output signal is similar to that of the input signal, only amplified by a fixed coefficient. In contrast, the output signal of nonlinear integrated circuits exhibits a nonlinear response to the input signal, such as square or logarithmic relationships, hence the term nonlinear circuits. Common nonlinear circuits include oscillators, timers, and phase-locked loop circuits. Typical applications of analog integrated circuits are shown in the figure below: external natural signals collected by various sensors or antennas (temperature, humidity, optical, piezoelectric, acoustic, etc.) are preprocessed by analog circuits and converted into suitable digital signals for input into digital systems; signals processed by the digital system are then post-processed by analog circuits and converted into analog signals such as sound, images, and radio waves for output.

ACCUTECHNOLOGY electrical component principles

Electrodynamic loudspeakers, also known as moving-coil loudspeakers, are electroacoustic transducers applying the electrodynamic principle. They are the most widely used loudspeakers, primarily for three reasons: 1. Electrodynamic loudspeakers have a simple structure and are easy to manufacture, requiring no large space, which leads to low costs and widespread adoption. 2. These loudspeakers can achieve excellent performance, obtaining a uniform frequency response in the mid-frequency range. 3. These loudspeakers are continuously improving; decades of loudspeaker development history reflect continuous improvements in design, craftsmanship, and materials, as well as performance keeping pace with the times. Electrodynamic loudspeakers are mostly cone-shaped or dome-shaped. The structure of a cone loudspeaker can be divided into three parts: 1. The vibration system includes the diaphragm, voice coil, centering spider, and dust cap. 2. The magnetic circuit system includes the upper pole plate, pole piece, lower pole plate, and magnet. 5. The auxiliary system includes the basket, surround, terminal board, and phase plug. According to Faraday's law, when a current-carrying conductor passes through a magnetic field, it experiences an electromagnetic force. Its direction conforms to Fleming's left-hand rule, with the force perpendicular to both the current and the magnetic field directions. The magnitude of the force is proportional to the current, wire length, and magnetic flux density. When an alternating audio current is input to the voice coil, the coil experiences an alternating driving force, producing alternating motion that drives the paper cone to vibrate, repeatedly pushing air to generate sound.

ACCUTECHNOLOGY electrical component classification

Classification by operating principle or structural characteristics of relays: (1) Electromagnetic relay: An electrical relay that operates using the attractive force generated between the electromagnet core and the armature by the current in the input circuit. (2) Solid-state relay: A relay where electronic components perform functions without mechanical moving parts, providing isolation between input and output. (3) Temperature relay: A relay that operates when the ambient temperature reaches a specified value. (4) Reed relay: A relay that opens, closes, or switches circuits using the action of reed contacts sealed in a tube, which serve both as contact springs and part of the armature magnetic circuit. (5) Time delay relay: A relay whose output section delays or limits operation to a specified time before closing or opening the controlled circuit when an input signal is applied or removed. (6) High-frequency relay: A relay used for switching high-frequency and RF lines with minimal loss. (7) Polarized relay: A relay that operates due to the combined effect of a polarizing magnetic field and the magnetic field generated by the control current passing through the control coil. The operating direction of the relay depends on the direction of the current flowing through the control coil. (8) Other types of relays: Such as optical relays, acoustic relays, thermal relays, instrument relays, Hall effect relays, and differential relays.
