Thyristors - SCRs - Modules

Thyristors are a type of semiconductor device that can be used for switching and control applications. They are also known as Silicon Controlled Rectifiers (SCRs) or thyristor-controlled semiconductor modules (TCMSs). The MCMA120UJ1800ED is a two-channel module that is designed for switching and control of motor-driven loads.The MCMA120UJ1800ED is a compact, high-performance thyristor module with a three-phase single-phase bridge rectifier. It is composed of two individual thyristors connected in an inverse parallel configuration and is rated for an operating temperature range of -10°C to +85°C. The module is designed for use in applications such as motor control, AC phase control, DC to AC phase control, phase angle control switching and DC chopper control. The main feature of the MCMA120UJ1800ED is its two-channel design which allows for the control of two independent loads. The module utilizes an integrated gate drive circuit, making it ideal for applications in an environment with high electrical noise. The module is also equipped with a low on-state voltage drop and low gate current. The MCMA120UJ1800ED is also certified with UL, CUL and TUV standards. The working principle of the MCMA120UJ1800ED is based on the concept of self-latching thyristors. A thyristor is essentially a transistor with three terminals corresponding to the anode, cathode and gate. When a positive trigger voltage is applied to the gate, the thyristor will enter a conducting state, allowing current to flow from the anode to the cathode. When this current reaches a certain threshold, the thyristor will latch in its on state, allowing current to continue to flow even after the gate voltage is removed. The MCMA120UJ1800ED utilizes two of these thyristors in an inverse parallel configuration to control two independent loads. When two thyristors are connected in this manner, the module is able to switch two separate loads in a single cycle. This allows for better control and faster switching times than if two thyristors were connected in a series configuration.The module is also equipped with a zero-cross feature which allows for control of applications in AC power systems. The feature is activated when a signal is sent to the module’s zero-cross pin at the time when the AC voltage passes through zero. With this feature, the MCMA120UJ1800ED can be used to control applications such as AC motor speed control and AC phase angle control.In summary, the MCMA120UJ1800ED is a two-channel thyristor module designed for use in applications such as motor control, AC phase control, DC to AC phase control, phase angle control switching, and DC chopper control. The module utilizes an integrated gate drive circuit to reduce electrical noise, and also features a zero-cross feature for AC power system applications. Its two-channel design allows for control of two independent loads in a single cycle, providing increased control and faster switching times.
