Solid State Relays

Solid state relays, also known as SSRs, are electromechanical relays with an electronic switching device, usually a MOSFET or an IGBT, as their internal switching system. They are used as an interface between a control system, such as a computer, and an electrically isolated, or AC-driven, load. Solid state relays typically provide a high level of isolation between the input and output signals, allowing control of the load with a low-power, low-voltage signal. The AQW212SX is a popular, high-performance SSR that is used in a wide range of applications.

The AQW212SX is a 5A AC/DC SSR designed to control AC or DC current loads up to 5 Amps. It is an ideal solution for industrial automation applications requiring a high level of safety and reliability. The AQW212SX has a wide operating temperature range of -30 to +85°C, and is UL listed and CE marked. The device features a high-speed response time (switch ON/OFF time <7ms) and superior accuracy (voltage 0.1A) making it suitable for applications where precise and reliable switching is required.

The AQW212SX works on the principle of a dual thyristor trigger circuit. This circuit utilizes two thyristors of opposite conductive polarities which are triggered in tandem to close the switch. This is done balance the power supply of the two thyristors, allowing for a more reliable operation with less power loss. The switch is held in the on position as long as the input signal is maintained. When the input voltage is removed, the switch is automatically switched off. This principle also makes the AQW212SX suitable for use in both AC and DC driven applications.

The AQW212SX is widely used in a variety of industrial automation, energy management, and HVAC/R applications. In industrial automation, it is often used to control AC or DC current for motor control, lighting, conveying, and other production line applications. In energy management applications, it is used to convert mains frequency to control frequency so that machines can be operated in time and energy saving stages. In HVAC/R applications, it is often used as a controller to switch on/off motors, fans and pumps.

The AQW212SX is a reliable and cost-effective choice for any industrial automation application. Its wide operating temperature range and high-speed response time make it suitable for applications requiring precise and reliable switching. It is an ideal choice for applications requiring a high level of safety and reliability.
