Introduction

Thyristors are semiconductor devices that act as switches to control the flow of electric current. They are made of a combination of four layers of semiconductor materials that form the thyristor structure. Among these four layers, the central layer is called the control layer, which determines the working principle of thyristors. Among various types of thyristors, Silicon Controlled Rectifiers (SCRs) are the most commonly used thyristors.

TT104N12KOFB2

TT104N1200FB2 is commonly used hoist thyristor module manufactured by Siemens, which is a two-part series of SCR. This module is designed for the applications that need precise and repeated switching operations, such as industrial hoists, elevator controls and other mechanical devices.

TT104N12KOFB2 Application Field

Typically, TT104N12KOFB2 is adopted to run with a DC injection brake circuit for precise driving efficiency and frequently repeated switching operations in hoists and elevators. Because the American standard of TT104N12KOFB2 has a twelfth pole, it is especially suitable for installation and maintenance of motorized rolling gates, carports and elevators with higher torque. This thyristor module is also applicable in regular AC switch control systems and is widely used in various industrial control, automotive and other applications.

TT104N12KOFB2 Working Principle

The working principle of TT104N12KOFB2 is based on the dynamic self-commutation technology, which eliminates the need for an external commutating circuit and greatly simplifies the circuit design.When the switch is in the OFF position, the current is blocked by the control layer. As soon as the control terminal voltage is over a certain voltage and the control current is above a certain current or a certain frequency, the device will switch from OFF to ON state. During this process, the central control layer will conduct current and the current will flow continuously between the two electrodes as long as the voltage between the electrodes is maintained.When the control voltage falls below a certain voltage and the control current falls below a certain current or a certain frequency, the device will switch from ON to OFF state, and the central control layer will block current, thus blocking the current flow between the two electrodes.

Conclusion

In conclusion, the TT104N12KOFB2 thyristor module is widely used in various industrial control, automotive and other applications due to its precise and repeated switching operations, dynamic self-commutation technology, and its suitability for motorized rolling gates, carports and elevators with higher torque. This thyristor module is essential in industrial hoists, elevator controls and other mechanical devices as it allows precise and reliable driving.
