Solid State Relay Basics: Working, Features and Structure17 September 2020
Solid State Relay (SSR) is a non-contact switch composed of microelectronic circuits, discrete electronic devices, and power electronic power devices. The isolation device is used to realize the isolation between the control end and the load end. The input terminal of the solid state relay uses a tiny control signal to directly drive a large current load.
An Overview of Isolation Transformers17 September 2020
An isolation transformer is a transformer in which the input and output windings are electrically isolated. The isolation transformer is to isolate the current of the primary winding and the secondary winding respectively.
Introduction to Mass Air Flow Sensor15 September 2020
Mass air flow sensor is one of the important sensors of EFI engines. It converts the inhaled air flow into an electric signal and sends it to the electronic control unit (ECU). As one of the basic signals for determining fuel injection, it is a sensor that measures the air flow into the engine.
Basic Understanding of Attenuators15 September 2020
An attenuator is used to introduce a predetermined attenuation within a specified frequency range. It is generally indicated by the decibel of the attenuation introduced and the ohm of its characteristic impedance.
What is a Gyroscope Sensor?11 September 2020
A gyroscope is a device used to sense and maintain direction, designed based on the theory of indestructible angular momentum. The gyroscope sensor is a simple and easy-to-use positioning and control system based on free space movement and gestures.
Introduction to TRIAC and TRIAC Dimmer10 September 2020
TRIAC is developed based on ordinary thyristors. It can not only replace two thyristors connected in parallel with reverse polarity, but also only needs one trigger circuit, which is an ideal AC switching device...
Multivibrator: Circuits, Types and Application08 September 2020
A multivibrator uses deep positive feedback, to turn on and off two electronic devices alternately through the resistance-capacitance coupling, thereby self-excites and generates a square wave output. It's often used as a square wave generator...
What are Programmable Logic Controllers?07 September 2020
Programmable Logic Controller(PLC) is an electronic system operated by digital operations, specially designed for application in an industrial environment. It uses a memory that can be programmed to execute instructions for storing logical operations and sequence control, timing, counting and arithmetic operations.
What is a Radar Sensor?04 September 2020
A radar sensor is a conversion device that can convert microwave echo signals into electrical signals. The radar sensing is a wireless sensing technology that extracts and discovers the target's position, shape, motion characteristics and motion trajectory by analyzing the received target echo characteristics.
Introduction to Voltage Stabilizer03 September 2020
A voltage stabilizer is a device that stabilizes the output voltage. The voltage stabilizer is composed of a voltage stabilizer circuit, a control circuit, and a servo motor. When the input voltage or load changes, the control circuit samples, compares, and amplifies, and then drives the servo motor to rotate to change the position of the carbon brush of the voltage stabilizer. The coil turns ratio is automatically adjusted to keep the output voltage stable.
What is Digital Counter?01 September 2020
Counting is one of the simplest basic operations. In digital logic and computing, the counter is the logic circuit that realizes this kind of operation. In the digital system, the counter mainly counts the number of pulses to realize the functions of measurement, counting, and control.
LED Driver: Function, Types, and Application01 September 2020
LED Driver refers to the power adjustment electronic device that drives LED light or LED module components work normally. Due to the conduction characteristics of the LED PN junction, the voltage and current range of the power supply it can adapt to is very narrow, and a slight deviation may not be able to light the LED, or the luminous efficiency will be seriously reduced, or the service life may be shortened or the chip may be burned.
