Solid State Relays

A solid-state relay (SSR) is an electronic switching device that switches on or off when a small external voltage is applied across its control terminals. The AQY210KS is a high-performance, ultra-reliable solid state relay that offers a wide range of operational features, making it ideal for a wide range of applications.

Application Field

The AQY210KS is most commonly used in industrial automation systems and motor control systems. It is specifically designed for use in contactor-style applications, including switching and controlling AC motors and AC loads. The AQY210KS relay is also suitable for use in high-current applications that require precise voltage/power control and efficient heat dissipation.The AQY210KS is an ideal solution for applications that require high-current switching, such as machine tools, welding systems and robotics. The AQY210KS is also perfectly suited for applications where precise, reliable switching is required at high cycle times, for example, in semiconductor manufacturing processes.

Working Principle

The AQY210KS relay is a zero-crossing SSR (solid state relay) that uses a high-performance tri-level switching principle for efficient, reliable switching. This combination of fast-acting circuits and efficient solid state switch technology enables the AQY210KS to quickly and accurately switch power between two circuits, while dissipating heat quickly and effectively.In operation, a tiny current is sent through the two control terminals of the AQY210KS solid state relay. This small current triggers the switching of an internal switch, which activates the control circuit and provides the power required for the output relay to begin switching. The AQY210KS then draws a small amount of power from the AC mains and dissipates the remaining power through its heat sink, keeping the temperature of the output switch stable and reducing energy losses.The AQY210KS also features a ground leakage protection circuit that helps to protect the device from overloading, making it suitable for use in high-powered industrial applications.In conclusion, the AQY210KS is a high-performance, ultra-reliable solid state relay that offers a wide range of operational features, making it ideal for use in a variety of industrial automation and motor control applications. Its advanced switching principle and ground leakage protection circuit ensures reliable and efficient switching, while its high-efficiency heat sink ensures the device operates at optimal temperature levels.
