What is a Reed Relay?16 April 2021
A reed relay is a type of relay that uses an electromagnet to act directly on the reed-like contact of a reed switch contained within a glass envelope, typically bringing the reeds together to make contact when the electromagnet is powered.
Introduction to MD8002A Audio Amplifier27 March 2025
The MD8002A is an audio power amplifier that uses a 5V DC power supply to provide 2.0 watts of continuous power to a BTL load with less than 10% distortion. It was created with the aim of providing high-quality o/p control with fewer components. It doesn't use any output coupling capacitors or bootstrap capacitors.
Facial Recognition: Features, Working and Applications02 September 2021
The broad sense of facial recognition includes a series of technologies for building a facial recognition system, including face image acquisition, face positioning, facial recognition preprocessing, identity confirmation, and identity search, etc… The narrow sense of facial recognition refers specifically to the adoption of the system for confirming or finding the identity of a human face.
Introduction to Distribution Transformer24 February 2021
Often known as a common kind of isolation transformer is a distribution transformer. The key purpose of this transformer is to adjust the high voltage to the standard voltage to be used in electrical power delivery, such as 240/120 V. There are distinct types of transformers available in the delivery chain, such as single phase, 3-phase, underground, pad-mounted, pole-mounted transformers.
New Crisis in Semiconductors: Neon Gas Prices Soar 9 Times21 March 2022
According to MoneyDJ, the war between Russia and Ukraine has halted the operations of the Ukrainian industry, which supplies half of the world's neon gas, and the price of neon has soared nearly nine times in China. Neon is a key raw material for chip manufacturing, which has cast a shadow over the global semiconductor supply.

How to Use an External Hard Drive?24 June 2021
The external hard drive is a compact and portable hard drive storage which can be plugged in or unplugged at any time. It mainly uses USB or IEEE1394 interfaces. It can transmit data with the system at a higher speed. The IEEE 1394 interface transfer rate is 50-100 MB/s.
What is an Auto Transformer and Its Working?01 April 2021
Auto transformer refers to a transformer whose primary and secondary windings are on the same winding, and the primary and secondary windings are directly connected in series and self-coupled. According to the structure, it can be subdivided into adjustable pressure type and fixed type. Auto-coupling means electromagnetic coupling. Ordinary transformers transfer energy through the electromagnetic coupling of the primary and secondary coils. There is no direct electrical connection between the primary and secondary sides. The primary and secondary sides of the auto transformer have direct electrical connections. Its low-voltage coils It is part of the high voltage coil. Protective equipment such as auto transformers are also used in protective equipment for communication lines.

Introduction to RAID (Redundant Arrays of Independent Disks)01 July 2021
RAID (Redundant Arrays of Independent Disks) means "a redundant array composed of independent disks". The RAID is the combination of many independent disks that combined into a large-capacity disk group. It uses the bonus effect of individual disks to provide data to enhance the performance of the entire disk system.
