Solid State Relays: AQR40A2-S-Z18/28VDC

Solid state relays (SSRs) are an electrical switching device that uses semiconductors and mechanical relays. They are typically used in applications where a low-level signal requires the control of a higher-power circuit. The AQR40A2-S-Z18/28VDC is a type of SSR which offers a high current and voltage rating for control of resistive, inductive and capacitive loads.The AQR40A2-S-Z18/28VDC application field includes industrial automation, automotive, wind turbines, heating systems and other medical devices. It can be used to switch large batteries or other heavy duty applications requiring low leakage current. Furthermore, it offers the ability to connect up to 40A of load current with both AC and DC loads.The AQR40A2-S-Z18/28VDC SSR consists of two parts, an input and an output, which are connected together with a variety of different control methods. The input consists of an AC voltage, while the output is DC in nature. The working principle of the AQR40A2-S-Z18/28VDC is based on the switching effect produced when an electric current is passed through a semiconductor diode. When a signal is applied to the input of the SSR, it provides an electrical current through the gate. This current allows the power switches to conduct electricity, thus allowing current to flow through the output of the SSR. The AQR40A2-S-Z18/28VDC boasts a fast switching time from 0.1ms up to 10ms, providing the highest efficiency and performance in industrial applications. Furthermore, it features a wide operating temperature range of -40 to 85°C, and is suitable for a wide range of applications. The AQR40A2-S-Z18/28VDC also offers the ability to continuously monitor its own electrical characteristics, providing protection to the load by detecting abnormally high voltages or currents. It also ensures that the load is correctly identified via an integrated current sensing protection circuit. In summary, the AQR40A2-S-Z18/28VDC is a high-performance solid state relay ideal for industrial automation, automotive, wind turbines, heating systems and other medical devices with a wide temperature range and fast switching time. It is designed for low leakage current with the ability to continuously monitor its own electrical characteristics for protection.
