MDEXX electrical components, German MDEXX models, MDEXX pricing

MDEXX electrical components refer to switching devices capable of closing, carrying, and breaking current under normal circuit conditions, and of closing, carrying, and breaking current under abnormal circuit conditions within a specified time. Circuit breakers are classified into high-voltage and low-voltage types based on their application range. The boundary between high and low voltage is somewhat ambiguous; generally, equipment rated above 3kV is considered high-voltage apparatus. Circuit breakers can be used to distribute electrical energy, start asynchronous motors infrequently, and protect power lines and motors. They automatically interrupt the circuit in the event of severe faults such as overload, short circuit, or undervoltage. Their function is equivalent to a combination of fuse-switches and over/under-voltage thermal relays. Moreover, component replacement is generally not required after interrupting fault currents. They have been widely applied. In the generation, transmission, and use of electricity, power distribution is an extremely important link. Distribution systems include transformers and various high- and low-voltage electrical equipment, with low-voltage circuit breakers being a widely used type of electrical apparatus.

MDEXX electrical component applications

Wire and cable products used in power systems mainly include bare overhead wires, busbars (bus ducts), power cables (plastic-insulated cables, oil-impregnated paper-insulated power cables (largely replaced by plastic-insulated power cables), rubber-sheathed cables, overhead insulated cables), branch cables (replacing some busbars), magnet wires, and electrical equipment wires and cables for power equipment. Wire and cable products used in information transmission systems mainly include telephone cables, television cables, electronic wires, RF cables, fiber optic cables, data cables, magnet wires, power communication cables, and other composite cables. Apart from bare overhead wires, almost all other products in this category have applications, but the main ones are power cables, magnet wires, data cables, and instrument cables.

MDEXX electrical component types

For different application scenarios, the purpose of applying varistors, the voltage/current acting on the varistor should not be the same, therefore the requirements for the varistor are also different. Pay attention to distinguishing these differences, which is very important for correct use. According to different application purposes, varistors can be divided into two major categories: (1) protection varistors, (2) circuit function varistors. Protection varistors: (1) Distinguish whether they are power supply protection varistors, or signal line and data line protection varistors; they must meet the requirements of different technical standards. (2) According to the different continuous operating voltages applied to the varistor, varistors used across power lines can be divided into two types: AC type or DC type. The aging characteristics of varistors under these two voltage stresses are different. (3) According to the different abnormal overvoltage characteristics withstandable by the varistor, varistors can be divided into three types: surge suppression type, high-power type, and high-energy type. 1. Surge suppression type varistors refer to varistors used to suppress transient overvoltages such as lightning overvoltage and switching overvoltage, the occurrence of this transient overvoltage is random, non-periodic, and the peak current and voltage may be very high. The vast majority of varistors belong to this category. 2. High-power type varistors refer to varistors used to absorb periodically occurring continuous pulse groups, for example, varistors connected in parallel to switching power supply converters, Impulse voltage occurs periodically here, and the period is known, the energy value can generally be calculated, the peak voltage is not high, but due to the high frequency of occurrence, its average power is considerable. 6. High-energy varistors refer to varistors used to absorb magnetic energy in large inductive coils such as generator excitation coils, lifting electromagnet coils, for such applications, the main technical indicator is energy absorption capacity. The protective function of varistors, in the vast majority of application scenarios, can act repeatedly multiple times, but sometimes they are also made into "one-time" protective devices like current fuses. For example, varistors with short-circuit contacts connected in parallel to the loads of certain current transformers.

MDEXX electrical component applications

PN junction photodiodes, like other types of photodetectors, are widely used in devices such as photoresistors, charge-coupled devices (CCDs), and photomultiplier tubes. They can output corresponding analog electrical signals based on the illuminance of received light or switch between different states in digital circuits. Photodiodes are also used in consumer electronics, such as CD players, smoke detectors, and infrared remote control devices for televisions and air conditioners. For many applications, photodiodes or other photoconductive materials can be used. They are often used for light measurement, frequently operating in camera light meters and automatic brightness adjustment for street lights. All types of optical sensors can be used to detect sudden light exposure or to detect light emission within the same circuit system. Photodiodes are often combined with light-emitting devices to form a module, commonly known as an optocoupler. This allows the analysis of external mechanical component motion by analyzing the received light conditions. Another function of photodiodes is to act as an intermediary between analog and digital circuits, allowing the two circuit segments to be coupled via optical signals, which improves circuit safety. In scientific research and industry, photodiodes are often used for precise light intensity measurement because they offer better linearity than other photoconductive materials. Photodiodes are also widely used in medical equipment, such as X ray computed tomography and pulse detectors. PIN junction photodiodes are generally not used to measure very low light intensities. If high-sensitivity detectors are required under weak light conditions, avalanche photodiodes, charge-coupled devices (CCDs), or photomultiplier tubes can be employed, such as in astronomy, spectroscopy, night vision equipment, and laser rangefinders.
