Thyristors - SCRs - Modules: MMO140-16IO7 Application Field and Working Principle

The MMO140-16IO7 is a part of the thyristor-controlled modules family. It is an advanced module with an integrated gate and driver circuit, and the capability of controlling four SCRs. The Thyristors-SCRs-Modules technology uses solid-state devices consisting of two terminals – the gate and cathode – which provide a controlled switch to the circuit. This device is typically used in applications such as power control, motor control, switching regulators, bridge rectifiers and others.

The MMO140-16IO7 offers excellent performance due to its low on-state voltage drop, high voltage and current ratings, fast response times and its robust construction. Additionally, the module features this feature: Inrush limiting circuit. This feature prevents the inrush current from reaching the output circuit, thus reducing the risk of damage to the module.

The module\'s main application fields are: AC motor controllers, DC motor controllers, solenoid valves, switching power supplies, adjustable speed drives and pressure switches. The module\'s applications also extend to industrial applications. Some examples include controlling and coordinating machine tools, hoists and cranes, lifts and conveyors and motion control systems. All these applications require precise triggering and safe operation of the thyristor control unit.

The key elements of the working principle of the MMO140-16IO7 are based on the thyristor device. The device is triggered by a specific voltage known as the gate trigger voltage when the voltage across the gate and cathode terminals reaches a certain threshold value. The gate trigger voltage required for this device is usually between 5 and 7 volts. Once the thyristor is triggered, it starts to conduct current through the system. To turn off the thyristor, the control unit needs to be connected to an external device that can disconnect the control voltage from the thyristor. The module features an inrush limiting circuit which helps with this.

The module contains several other components including a power supply and the control logic, a power amplifier and a bridge rectifier. The power supply provides the necessary power needed to operate the device, while the control logic enables the module to provide the precise timing of the device. The power amplifier is responsible for providing the necessary power to the thyristor in order to activate it. The bridge rectifier helps to balance the power across the two ends of the thyristor, which helps maintain a uniform load current throughout the system.

The MMO140-16IO7 is a robust device, and its construction and design provide it with a long-term operation period. It is one of the most reliable and robust thyristor-controlled modules on the market, making it a great choice for a variety of applications. The module is highly efficient and features high voltage and current rating, making it suitable for a range of applications.
