The IRKT71/14A is capable of controlling the power of up to seven amperes, with a reactive power of up to three amperes. It can be used to efficiently switch up to a maximum of 120 VDC and 277 VAC.

Application Fields

Due to its wide range of features and applications, the IRKT71/14A module is used in various industries. One of the major applications of this module is in the automotive and industrial fields. It can be used to control power and heat in automobiles, electric motors, pumps, fans, and other industrial and automotive equipment. It is also used in power-conversion devices such as UPS (uninterruptible power supply) systems and solar photovoltaic cells. Other applications include homelighting, portable power tools, scientific and industrial measuring instruments, and security systems.

Working Principle

The working principle of the IRKT71/14A module is based on the principles of SCR, or silicon-controlled rectifier. It is a semiconductor device composed of a p-n junction, which consists of a single SCR and a single diode connected in series. When AC input voltage is applied to the SCR, it turns on and conducts current. This current flows in a forward direction and is blocked in a reverse direction. The diode works in a similar way, but the direction of current is reversed.

The IRKT71/14A module is also equipped with a triggering system, which allows for the control of the power conduction of the SCR and diode. The triggering system also allows for the control of the power conduction time, which is estimated according to the current and voltage settings of the SCR. The module operates on the principle of a three-phase, full-wave bridge rectifier, which is used to convert AC power to DC or vice versa.

In a three-phase system, the current flow is reversed in two of the three phases at any given time, which is why the IRKT71/14A module needs to be connected to all three phases in order to ensure that the current flow is consistent. The triggering system also allows for the control of the power conduction time, which is estimated according to the current and voltage settings of the SCR.

Conclusion

The IRKT71/14A module is a highly advanced SCR module that is designed for use in various applications. It is suitable for use in power-conversion devices, automotive, industrial, and home-lighting applications and other related applications. Its superior performance and heat management make it a reliable and cost-effective power control solution. The IRKT71/14A works on the principles of an SCR and a three-phase, full-wave bridge rectifier to convert AC to DC power or vice versa, as well as controlling the power conduction time.
