ADJ21005 application field and working principle

ADJ21005 is a low-signal electronic power relay, which is widely used in power supply and plays an important role in motor, transformer, electric furnace and various occasions of charging and discharging. It is a kind of automatic control device.

The ADJ21005 relay is an electronic power relay based on BJT and double way thyristor. Its functions mainly include overvoltage protection, current limit protection, temperature protection, automatic on/off control and other functions. Its working state can be realized through the output signal of the microprocessor or logic module. It is stable in use and has a wide range of applications.

The application field of ADJ21005 relay mainly includes overvoltage protection, current limit protection, temperature protection and other fields. The overvoltage protection of ADJ21005 relay mainly includes the overvoltage protection of integrated driving circuit, the overvoltage protection of video circuit or analog circuit and the overvoltage protection of peripheral power supply. In the overvoltage protection of AC power, the 3-level integrated driving circuit of ADJ21005 relay is used to realize the overvoltage protection.

In particular, this type of relay can be used in the protection of AC power systems, such as power supply and power factor compensation motor control system, power supply voltage stabilization system, power cycling circuit system, heating and air conditioning circulation system, etc. In addition, ADJ21005 relay also has the function of current limit protection. It can limit the maximum output current and protect the power device from damage.

The temperature protection is also an important application field of this type of relay. ADJ21005 relay can be used to detect the temperature in the electric heating equipment. When a certain temperature is detected, ADJ21005 relay can be triggered and the output power of the electric heating equipment is cut off.

ADJ21005 relay is composed of solid state components like transistors, thyristors and diode, which can replace the traditional mechanical relays. The working principle of this type of relay is to detect the input signal and give reaction. The output voltage is controlled by the conduction and cutoff of thyristors. The protection function of ADJ21005 relay plays an important role in recognizing the input signal, identifying the existence of dangerous signal and outputting the trigger signal when the predetermined value is exceeded.

In a nut shell, the application field and working principle of ADJ21005 are closely related. ADJ21005 relay can be used in the overvoltage protection, current limit protection, temperature protection and other fields with its characteristics of low power consumption, high sensitivity and long service life, which plays an important role in the industry.
