Solid State Relays are an important component in the world of power electronics. They provide a reliable and efficient way to switch power and protect expensive electronic components from overvoltage, over-current and other types of interference. The AQ1AD2-3/28VDC solid state relay is an integrated, three-terminal, single-pole double-throw, bidirectional device that is used for AC and DC switching applications. It is a popular choice for a wide range of industrial applications, such as remote control, security, control circuit and HVAC systems.

The AQ1AD2-3/28VDC relay consists of a LED optically coupled to a MOSFET. It is suitable for a wide range of AC and DC loads, including resistive and inductive loads. It also features a ‘control’ terminal which is used to control the relay’s on/off switching. When the control voltage is applied to the control terminal, the LED is energised and switches the connected load on. When the control voltage is removed, the LED will be de-energised and the load will be switched off.

The AQ1AD2-3/28VDC relay has a very versatile application field. It can be used for switching applications in remote control systems, access control, security systems, HVAC systems, motor control and many other industrial equipment. It is also an ideal choice for any application that requires fast switching between AC and DC loads.

In terms of working principle, when the control terminal of the solid state relay is enabled, current passes from the circuit, through the LED and MOSFET, to the load. The MOSFET then switches the load on or off depending on the status of the control terminal. When the control voltage is removed, the MOSFET switches off and the load is disconnected. In this way, the AQ1AD2-3/28VDC relay works as an efficient, reliable and safe way to switch AC and DC circuits.

The AQ1AD2-3/28VDC relay has a range of features that makes it suitable for a wide range of applications. It has a fast switching speed, is highly reliable and durable, and is capable of handling higher current levels than other solid state relays. It is also capable of working in harsh environments and has a long service life due to its robust construction.

In conclusion, the AQ1AD2-3/28VDC solid state relay is an excellent choice for a variety of AC and DC switching applications. It is a reliable, efficient and cost-effective way to switch power and protect expensive electronic components from overvoltage, over-current and other types of interference. It has a wide application field and is capable of handling higher current levels than other solid state relays, making it an ideal choice for industrial and commercial applications.
