bioledex electrical components Germany bioledex model bioledex price

bioledex electrical components are surge absorbers/varistor assemblies. Due to the nonlinear resistance change with respect to voltage, they exhibit symmetry in both directions (positive and negative). They respond to abnormal voltages on the line, absorbing most of the surge/spike energy while suppressing the abnormal voltage to a safe range, thereby improving the safety and stability of the circuit. In the standby state, the surge absorber (varistor) has very high impedance (several megaohms) relative to the protected electronic components and does not affect the characteristics of the original design circuit. However, when an instantaneous surge voltage occurs (exceeding the breakdown voltage of the surge absorber), the impedance of the surge absorber drops low (only a few ohms), causing a short circuit in the line, thereby protecting electronic products or more expensive components.

bioledex electrical component principle

In addition to the function of converting optical signals into electrical signals like a photodiode, a phototransistor also amplifies electrical signals. The appearance of a phototransistor is not much different from that of a general transistor. Generally, a phototransistor has only two terminals led out—the emitter and the collector—while the base is not led out. The casing also has a window to allow light to enter. To increase light exposure, the base region area is made large, while the emitter region is small; incident light is mainly absorbed by the base region. During operation, the collector junction is reverse-biased, and the emitter junction is forward-biased. In the absence of light, the current flowing through the tube is the dark current Iceo = (1 + β) Icbo (very small), which is smaller than the penetration current of general transistors. When illuminated, a large number of electron-hole pairs are generated, increasing the base current Ib. The current flowing through the tube at this moment is called the photocurrent, and the emitter current Ie = (5 + β) Ib. It can be seen that the phototransistor has higher sensitivity than the photodiode.

bioledex electrical component principle

A transformer is a device that changes AC voltage using the principle of electromagnetic induction. Its main components are the primary coil, secondary coil, and iron core (magnetic core). In electrical equipment and wireless circuits, it is commonly used for stepping voltage up or down, impedance matching, and safety isolation. In generators, whether the coil moves through a magnetic field or the magnetic field moves through a fixed coil, an electromotive force is induced in the coil. In both cases, the value of the magnetic flux remains unchanged, but the amount of magnetic flux linking with the coil varies; this is the principle of mutual induction. A transformer is a device that utilizes electromagnetic mutual induction to transform voltage, current, and impedance.

bioledex electrical component characteristics

So-called dynamic characteristics refer to the output characteristics of a sensor when the input changes. In practical work, the dynamic characteristics of a sensor are often expressed by its response to certain standard input signals. This is because the sensor's response to standard input signals is easily obtained through experimental methods, and there is a certain relationship between its response to standard input signals and its response to arbitrary input signals; often, knowing the former allows inference of the latter. The most commonly used standard input signals are step signals and sinusoidal signals, so the dynamic characteristics of sensors are also commonly expressed by step response and frequency response.
