AB MITSUBISHI 81001-450-53-R SCR Circuit board Product Details:

Thyristor modules are semiconductor electronic devices commonly used in power control and power regulation applications. It is also often referred to as a thyristor switch, Silicon Controlled Rectifier, or simply SCR (Silicon Controlled Rectifier). The following is some basic information about thyristor modules:

81001-450-53-R Principle: The thyristor module works based on the characteristics of semiconductor silicon materials. It can control the current flow by turning on or off under the pulse signal of the control voltage, thus realizing the control of voltage and current.

Application: Thyristor modules are widely used in power control, power regulation, lighting control, heating control, motor control, AC power control and various industrial automation applications.

Features: The thyristor module has the advantages of fast response time, high current bearing capacity, high efficiency and low maintenance cost. They can be used for high current, high pressure applications.

81001-450-53-R Control mode: The thyristor module can be controlled by means of pulse width modulation (PWM) or pulse frequency modulation (PFM) to achieve accurate voltage and current control.

Protection: In the use of thyristor modules, it is usually necessary to consider safety measures such as overheat protection, overcurrent protection and overvoltage protection to ensure the safety and reliability of the equipment.

81001-450-53-R IGCT drive module ABB circuit board PLC module card servo controller, in the speed closed loop of the servo driver, the real-time speed measurement accuracy of the motor rotor is very important to improve the dynamic and static characteristics of the speed control of the speed ring. To seek measurement accuracy and system cost

Balance, generally using the star type photoelectric encoder as a speed sensor, and the corresponding common speed measurement method is M/T speed measurement. Although M/T velocity measurement method has a certain measurement accuracy and wider

Measurement range, but this method has its inherent defects, mainly including :1) the speed measurement cycle must detect at least one complete code pulse, limiting the measurable speed; 2) For speed measurement

The timing switches of the two control systems are difficult to keep strict synchronization, and the measurement accuracy cannot be guaranteed in the measurement occasions with large speed changes. Therefore, it is difficult to apply the traditional velocity loop design scheme of the velocity measurement method
