Circuit protection is mainly supported by over-voltage protection devices, over-current protection devices and over-temperature protection device components

For circuit protection of video surveillance systems in security equipment, a common power supply protection scheme is to use a bidirectional TVS diode across the input and power supply. The bidirectional diode is chosen to avoid the line voltage regardless of the polarity

Product quality is the fundamental to increase the sales of lightning arresters, followed by production technology

Experience sharing of senior electronic engineers' protective device selection indicators, as well as the main indicators of protective device performance.

The working principle of the diode, the formation of the crystal diode

Regarding circuit over-current protection, there are many ways, commonly used circuit protection with thyristor as the core, circuit protection with useful transistor as the core, circuit protection with useful relay as the core, useful disposable fuses, useful bimetallic strips The temperature control circuit, also useful ASIC protector and so on.

Regardless of the appearance of any electronic product, circuit protectors are inseparable, because the circuit needs circuit protection devices to prevent overcurrent from damaging the electronic product itself

In this chapter, Ruilongyuan engineers explain the functions of six common basic circuit protection components. These components are discharge tube, transient suppression diode, varistor, chip varistor, ESD electrostatic discharge diode and PTC self-recovery protection. ​Fuse.

In the process of LED display production, storage, installation and use, it is very easy to generate static electricity. The engineer of Ruilongyuan will explain to you how to prevent static electricity of the LED display.

Circuit protection is mainly to protect the components in electronic circuits from being damaged by overvoltage, overcurrent, surge, electromagnetic interference, etc., while circuit protection devices provide protection for the circuit and chip of the product to ensure that the circuit appears Under abnormal conditions, the precision chips and components of the protected circuit will not be damaged.

Our engineers from Ruilongyuan Electronics will give everyone a popular science: the mainstream products of circuit protection include TVS tubes, varistors, Zener diodes and self-recovery fuses.

The difference between positive and negative poles, color ring voltage regulator diodes, color ring voltage regulator diodes, and ordinary rectifier diodes.
