exsys.ch electrical components Germany exsys.ch model exsys.ch price

exsys.ch electrical components are instruments used to transform voltage. However, the purpose of a transformer's voltage transformation 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's voltage transformation is mainly to supply power to measuring instruments and relay protection devices, to measure line voltage, power, and energy, or to protect valuable equipment, motors, and transformers in the line when a fault occurs. Therefore, the capacity of voltage transformers 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 principle, they can be divided into electrodynamic (moving-coil), electrostatic (capacitive), electromagnetic (reed-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 enclosures. Classified by transduction mechanism and structure, there are moving-coil (electrodynamic), capacitive (electrostatic), piezoelectric (crystal or ceramic), electromagnetic (spring-armature), electrostatic ion, and pneumatic loudspeakers. Electrodynamic loudspeakers are widely used due to advantages such as good electro-acoustic performance, robust structure, and low cost. Classified by sound radiation material, there are paper cone, horn, and diaphragm types. Classified by paper cone shape, there are circular, oval, dual paper cone, and rubber surround types. Classified by operating frequency, there are bass, midrange, and treble; some are further divided 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-radiating and ambient sound types. Loudspeakers are divided into built-in and external loudspeakers, with external loudspeakers generally referring to speaker boxes. Built-in loudspeakers refer to MP4 players having built-in speakers, allowing users to listen to sound from the MP4 player not only through the headphone jack but also through the built-in speakers. MP7 players with built-in speakers can operate without external speakers and avoid the inconvenience of wearing headphones for extended periods.

exsys.ch electrical component applications

Specialized solid-state relays can feature short-circuit protection, overload protection, and overheat protection functions. When combined with hardwired logic encapsulation, they can realize intelligent modules required by users, directly applicable in control systems. Solid-state relays are widely used in computer peripheral interface equipment, temperature control systems, heating regulation, electric furnace heating control, motor control, CNC machinery, remote control systems, and industrial automation devices; signal lights, dimming, flashers, stage lighting control systems; instruments, medical devices, copiers, automatic washing machines; automatic fire fighting, security systems, and as switching switches for power capacitors for 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 its function 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 reeds sealed in a tube, which serve the dual function of contact springs and 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 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, differential relays, etc.
