Thyristors - TRIACs

L4004V5 is an advanced thick film hybrid circuit designed to facilitate the building of mains operated bidirectional motor control systems. It is typically used to control the speed of a motor by controlling the voltage or current value of a DC voltage circuit or a three-phase AC motor. It offers uncomplicated one-piece or multi-piece control systems, both of which can be used in a wide range of applications.

Application field

Due to its excellent reliability and EMI suppression, the L4004V5 has been widely used in the control systems of electric motors and in domestic applications, such heating regulator, door openers, light switches, etc. It is highly reliable, has excellent switching performance, and is shock and vibration resistant. In the control system of electric motors, the L4004V5 can effectively control the speed of the motor and improve the performance and energy efficiency of the motor.

The L4004V5 can also be applied to temperature control systems. Due to its high thermal performance, when used in an electric oven, the temperature fluctuations can be avoided. Furthermore, by employing a TRIAC as the temperature sensing component, a self-regulating temperature control system can be built, which will further improve the control accuracy of the system.

In addition to the mentioned applications, it has also been widely used in the control systems of elevators, home automation appliances, and industrial equipment.

Working principle

The working principle of the L4004V5 is based on the use of a thyristor. A thyristor or silicon-controlled rectifier (SCR) is a type of solid-state switch that is essentially a semiconductor device which can be used for the control of electric current. They can be used for switching, reversing, phase control, rectification, and numerous other applications.

When voltage is applied to the gate of the TRIAC, it becomes conductive, allowing current to flow from its anode to its cathode. As the TRIAC is bidirectional, it can be used for various applications. For example, in the control system of a motor, it can be used to reduce or increase the current by controlling the triggering angle. At the same time, the L4004V5 also provides EMI suppression, which optimizes the control performance of the system.

Conclusion

In conclusion, the L4004V5 is a pioneering thick film hybrid circuit designed to provide efficient and reliable motor control. It is typically used to control the speed of a motor by controlling the voltage or current value of a DC voltage circuit or a three-phase AC motor. Due to its excellent reliability and EMI suppression, the L4004V5 has been widely used in the control systems of electric motors and in domestic applications.
