IKUSI electrical components Germany IKUSI model IKUSI price

IKUSI electrical component is an electrical control device. It is an electrical appliance that causes a predetermined step change in the controlled variable in the electrical output circuit when the change in the input quantity (excitation quantity) meets specified requirements. It has an interactive relationship between the control system (also known as the input loop) and the controlled system (also known as the output loop). It is usually applied in automated control circuits; it is essentially an "automatic switch" that uses a small current to control the operation of a large current. Therefore, it plays roles such as automatic regulation, safety protection, and circuit switching in the circuit. A relay is an electrical control device that can accept a specified input quantity and maintain it for a sufficient duration, causing a predetermined step change in the controlled variable in the electrical output circuit. When the input quantity drops to a certain level and remains there for a sufficient duration, it returns to its initial state.

IKUSI electrical component applications

Semiconductor diodes are used in almost all electronic circuits. The use of semiconductor diodes in circuits can protect the circuit and extend circuit life. The development of semiconductor diodes has optimized integrated circuits and played a positive role in various fields. Diodes play many roles in integrated circuits, maintaining their normal operation. The following briefly introduces the roles of diodes in the following four types of circuits. (1) Switching circuit: In digital and integrated circuits, the unidirectional conductivity of diodes is used to achieve circuit conduction or disconnection; this technology has been widely applied. Switching diodes can effectively protect the circuit, preventing damage due to short circuits and other issues, and can also realize the functions of traditional switches. Another characteristic of switching diodes is their fast switching speed, which is incomparable to traditional switches. (2) Limiter circuit: In electronic circuits, limiter circuits are commonly used to process various signals. They are used to selectively transmit part of the signal within a preset voltage level range. Most diodes can be used for limiting, but sometimes dedicated limiter diodes are required, such as when protecting instruments. (3) Voltage regulator circuit: Zener diodes are typically used in voltage regulator circuits. They are junction-type silicon semiconductor diodes manufactured using special processes. These special diodes have a high impurity concentration and a high charge density in the space charge region, making it easy to form a strong electric field. When the reverse voltage across the Zener diode reaches a certain value, the reverse current increases sharply, causing reverse breakdown. (11) Varactor circuit: Varactor diodes are commonly used in varactor circuits to achieve automatic frequency control, tuning, frequency modulation, and scanning oscillation.

IKUSI electrical component principle

The construction of a mercury switch is very simple. The exterior is a sealed cylindrical insulating housing containing approximately one-fifth mercury. Two wires leading from the inside are fixed at one end of the housing. This constitutes a mercury switch. Due to gravity, the mercury bead flows to the lower part of the container. If it simultaneously contacts both electrodes, the switch closes the circuit, turning the switch on. The shape of the container also affects the conditions under which the mercury bead contacts the electrodes.

IKUSI electrical component structure

A thermopile is a pyroelectric infrared sensor, a device composed of thermocouples. It is widely used as a temperature detection device in fields such as ear thermometers, radiation thermometers, electric ovens, and food temperature detection. It consists of two or more thermocouples connected in series, where the thermoelectric potentials output by each thermocouple are superimposed. It is used to measure small temperature differences or average temperatures. Structure of a thermopile: The radiation receiving surface is divided into several sections, each connected to a thermocouple. Connecting them in series forms a thermopile. Depending on the application, practical thermopiles can be made in wire-type and thin-film types, as well as multi-channel and array-type devices.
