AC-Marine electrical components Germany AC-Marine model AC-Marine price

AC-Marine electrical components are instruments that convert high primary current to low secondary current for measurement based on the principle of electromagnetic induction. A current transformer consists of a closed iron core and windings. Its primary winding has very few turns and is connected in series with the circuit where the current needs to be measured. Therefore, the full line current often flows through it. The secondary winding has more turns and is connected in series with measuring instruments and protection circuits. When the current transformer is in operation, its secondary circuit is always closed, so the impedance of the coils connected in series with the measuring instruments and protection circuits is very small, and the operating state of the current transformer is close to a short circuit. The current transformer converts high primary current to low secondary current for measurement; the secondary side must not be open-circuited.

AC-Marine electrical components function

Photoelectric switches can be used in various application scenarios. Avoid strong light sources; photoelectric switches generally operate stably under high ambient illumination. However, avoid aligning the sensor's optical axis directly with strong light sources such as sunlight or incandescent lamps. If the angle between the sensor (receiver) optical axis and the strong light source cannot be changed, install shading plates around the top of the sensor or fit a long shading tube. To prevent mutual interference: New photoelectric switches usually have automatic mutual interference prevention functions, so mutual interference is not a concern. However, when several sets of HGK series through-beam infrared photoelectric switches are installed close together in parallel, mutual interference between adjacent groups should be prevented. The most effective way to prevent this interference is to cross-set the transmitters and receivers, and when exceeding 3 groups, increase the distance between groups. Of course, using models with different frequencies is also a good method. For reflective photoelectric switches, an effective way to prevent mutual interference is to increase the spacing. Moreover, the greater the detection distance, the larger the spacing should be; the specific spacing should be determined based on debugging conditions. Of course, models with different operating frequencies can also be used. Influence of mirror angle: When the detected object is glossy or encounters a smooth metal surface, the reflectivity is generally very high, acting like a mirror. Adjust the installation angle so that its optical axis is not perpendicular to the detected object, thereby preventing malfunction. Eliminating background influence: When using reflective diffuse transmitters and receivers, sometimes because the detected object is close to the background, or the photoelectric switch or background is a smooth object with high reflectivity, the photoelectric switch may not detect stably. Therefore, you can switch to distance-limited transmitters and receivers, or adopt methods such as moving away from the background, removing the background, painting the background matte black, or making the background rough and dark to eliminate the influence. Use of self-diagnosis function: During installation or use, minor deviations in the optical axis, lens contamination, dust accumulation, external noise, or ambient temperature exceeding the range may occur due to table or background influences and vibration. These problems may cause the photoelectric switch to deviate from the stable operating zone. In this case, the self-diagnosis function of the photoelectric switch can be used to make the green stability indicator light notify, reminding the user to adjust it in time.

AC-Marine electrical components types

There are many types of loudspeakers. According to their transduction principles, they can be divided into electrodynamic (moving coil), electrostatic (capacitive), electromagnetic (armature), piezoelectric (crystal), etc.; the latter two are mostly used in rural wired broadcasting networks. According to frequency range, they can be divided into low-frequency, mid-frequency, and high-frequency loudspeakers, which are often used as combination loudspeakers in speaker boxes. According to transduction mechanism and structure, they are divided into moving coil (electrodynamic), capacitive (electrostatic), piezoelectric (crystal or ceramic), electromagnetic (spring-loaded), ionophone, and pneumatic loudspeakers. Electrodynamic loudspeakers are widely used due to advantages such as good electro-acoustic performance, sturdy structure, and low cost. According to sound radiation material, they are divided into cone, horn, and diaphragm types. According to cone shape, they are divided into circular, oval, double-cone, and rubber surround. According to operating frequency, they are divided into bass, midrange, and treble; some are further divided into recorder-specific, TV-specific, general, and hi-fi loudspeakers. According to voice coil impedance, they are divided into low impedance and high impedance. According to effect, they are divided into direct radiation and ambient sound, etc. Loudspeakers are divided into built-in and external loudspeakers, with external loudspeakers referring to what is commonly known as speaker boxes. Built-in loudspeakers mean that the MP4 player has built-in speakers, allowing users to listen to the sound emitted by the MP4 player not only through the headphone jack but also through the built-in speakers. MP6 players with built-in speakers can operate without external speaker boxes and avoid the inconvenience of wearing headphones for long periods.

AC-Marine electrical components features

1, the function of a varactor diode is based on the principle that the capacitance between the PN junction is variable. It is a semiconductor device used as a variable capacitor in high-frequency tuning, communication, and other circuits. A varactor diode belongs to reverse-biased diodes; changing the reverse bias voltage on its PN junction changes the PN junction capacitance. The higher the reverse bias voltage, the lower the junction capacitance. The relationship between reverse bias voltage and junction capacitance is nonlinear. 2, graph of the relationship between varactor diode capacitance value and reverse bias voltage: (a) Increased reverse bias causes decreased capacitance; (b) Decreased reverse bias causes increased capacitance. The capacitance tolerance range is the specified capacitance range of a varactor diode. The datasheet will display the minimum, nominal, and maximum values, which are often plotted on the graph.
