Solid state relays (SSRs) are a type of switching device that is used to control the electrical circuit by using an isolation device to switch between two states. The AQV454 is a series of SSRs developed by the company Avaya, which is designed to provide precise control and operations for a wide variety of electrical systems. This article will discuss the AQV454’s application field and working principle.

Application Field: The AQV454 SSRs are mainly used in industrial automation systems and are specifically designed for high switching frequency applications. They are capable of providing fast and precise switching operations for a wide variety of electrical systems such as AC, DC and stepper motors. In addition, they are used in applications that require highly accurate control, such as in temperature control systems and process control systems.

Working Principle: The AQV454 SSRs are solid state relays that work using a hybrid switching mechanism. The relays are powered by a DC voltage which is then converted to an AC voltage through an alternating current driven circuit. This AC voltage is then used to drive a power MOSFET through a magnetic coupling device. The power MOSFET then controls the switching of the internal relay and provides the desired switching action.

The AQV454 is specifically designed to be used in applications that require highly accurate and fast switching operations. The voltage and current ratings of the AQV454 SSRs are optimized for high switching frequency applications and can provide fast switching times as low as 20 microseconds. In addition, the AQV454 SSRs are designed to eliminate switching noise and electromagnetic interference, making them suitable for a variety of applications.
