In addition, the module can be used to control the voltage of AC motors and transformers, as well as to control the current of DC power supplies. Moreover, the IRKL105/04A module is also used as a protection device in industrial electrical systems.

The IRKL105/04A module works on the principle of silicon-controlled rectification. In this process, a power semiconductor is used to switch current between two parts of a circuit or is used to control the flow of current. The operation of the module is based on the application of a triggering voltage and a latching current. The triggering voltage is applied to the gate of the module and the latching current is separated by the SCR\'s junction capacitance.

When the triggering voltage is applied, the module switches on and a forward current starts to flow. Once the latching current is applied, the gate and the SCR\'s junction start to conduct in the same direction and become latched. This allows the power device to remain in the on-state, even after the triggering voltage is removed. Thus, the IRKL105/04A module can be used as a switch to control currents for various industrial applications.

In summary, the IRKL105/04A module is a powerful and reliable electrical device, part of the Thyristors-SCRs-Modules family. It offers a wide range of applications and its working principle focuses on the use of silicon-controlled rectification. This device proves to be highly efficient in terms of current and voltage handling, short-circuit protection, and surge currents withstanding, making it an excellent choice for a variety of industrial applications.
