IRKT26/04A

Thyristors are electrical devices made of semiconductor material like silicon. They are compact and efficient in controlling electric power in a wide range of applications, from the small consumer electronics to huge industrial power supplies. One type of thyristor is the SCR, or silicon controlled rectifier, which is used to switch power in a semiconductor device. Specifically, using SCRs as switch components allows for control of current to machines and lighting systems. The IRKT26/04A, a type of SCR module, is designed for high power applications with protection needed to prevent any damage to circuits or personnel.

The IRKT26/04A overview and specs reveal that it is a robust three-terminal device that is protected by a mold housing composed of epoxy and containing a thermistor. This thermistor is a temperature sensing device designed to protect the SCR against over-voltage and over-current conditions. The compact module is available in various ratings for both AC and DC applications such as loads up to 1000V, switching up to 6A, and temperature that reaches up to 100°C. Additionally, it features a special grip in its design for easy mounting and removal. The IRKT26/04A can be used in various applications such as power supplies, motor controls, robotics, and HVAC (heating, ventilation, and air conditioning) needs – mainly with single-phase AC motors.

The working principle of the IRKT26/04A is not complex at all. It is basically an electronic switch that is used to turn electric current ON and OFF. The module closes the circuit, or turns ON and allows the current to flow when a trigger voltage at its gate terminal is applied. The amount of current that flows through the device can be controlled by varying the applied voltage. When the trigger voltage is removed, the circuit will open and the current flow will stop. The thermistor prevents any damage or current surge due to over-heating issues.

In summary, the IRKT26/04A is a SCR module designed for high power applications with necessary protection devices that ensures safety in controlling electric current. It features special ratings such as 1000V and 6A for usage in AC and DC needs with temperature up to 100°C. Its thermistor-based temperature sensing device works to protect the SCR against any over-current or over-voltage conditions. This module is used mainly for single phase AC applications such as power supplies, motor control, HVAC, and robotics.
