exsys.ch electrical components German exsys.ch models exsys.ch prices

exsys.ch electrical components are instruments used to transform voltage. However, the purpose of a transformer in transforming voltage is to facilitate power transmission, so its capacity is large, generally calculated in kilovolt-amperes or megavolt-amperes; whereas the purpose of a voltage transformer in transforming voltage is mainly to supply power to measuring instruments and relay protection devices, to measure the voltage, power, and energy of the line, or to protect valuable equipment, motors, and transformers in the line when a fault occurs. Therefore, the capacity of a voltage transformer is very small, generally only a few volt-amperes or tens of volt-amperes, with a maximum not exceeding one thousand volt-amperes.

exsys.ch electrical component types

There are many types of loudspeakers. According to their transduction principles, they can be divided into electrodynamic (moving-coil), electrostatic (capacitive), electromagnetic (reed-armature), piezoelectric (crystal), and others; 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 combined loudspeakers in speaker enclosures. Classified by transduction mechanism and structure, there are 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 electroacoustic performance, robust structure, and low cost. Classified by sound radiation material, there are cone, horn, and diaphragm types. Classified by cone shape, there are circular, oval, dual-cone, and rubber surround types. Classified by operating frequency, there are woofers, midranges, and tweeters; some are further categorized into recorder-specific, TV-specific, general-purpose, and hi-fi loudspeakers. Classified by voice coil impedance, there are low-impedance and high-impedance types. Classified by effect, there are direct-radiation and ambient sound types. Loudspeakers are divided into built-in and external loudspeakers, with external loudspeakers commonly referred to as speaker enclosures. Built-in loudspeakers refer to speakers integrated into an MP4 player, allowing users to listen to audio from the MP4 player not only through the headphone jack but also through the built-in speakers. An MP7 player with built-in speakers eliminates the need for external speakers and avoids the inconvenience of wearing headphones for extended periods.

exsys.ch electrical component applications

Dedicated solid-state relays can feature short-circuit protection, overload protection, and overheat protection. When encapsulated with combination logic curing, they can realize intelligent modules required by users for direct use in control systems. Solid-state relays are widely used in computer peripheral interface equipment, constant temperature systems, temperature regulation, electric furnace heating control, motor control, CNC machinery, remote control systems, and industrial automation devices; signal lights, dimming, flashers, and stage lighting control systems; instruments, medical devices, copiers, and automatic washing machines; automatic fire fighting and security systems, as well as switching switches for power capacitors used in grid power factor compensation. Additionally, they are extensively used in chemical, coal mining, and other environments requiring explosion-proof, moisture-proof, and corrosion-resistant properties.

exsys.ch electrical component classification

Classification by relay operating principle or structural characteristics: (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 set value. (4) Reed relay: A relay that opens, closes, or switches circuits using the action of a reed sealed in a tube, which serves both as a contact spring and part of the armature magnetic circuit. (5) Time relay: A relay whose output section delays or limits operation to a specified time before closing or opening the controlled circuit upon application or removal of the input signal. (6) High-frequency relay: A relay used for switching high-frequency and RF lines with minimal loss. (7) Polarized relay: A relay that operates through 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.
