Solid State Relays (SSRs) are devices used to control large electrical currents. AQV259AZ is a type of SSR with a wide range of applications and functions. This article will discuss the application field and working principle of AQV259AZ.

Application Field of AQV259AZ

AQV259AZ is a type of SSR that is suitable for controlling appliance currents between 15 to 25 Amperes. It has a voltage rating of 30 VDC and is widely used in industrial operations such as ovens, refrigerators, air conditioners, and pumps.

AQV259AZ is also perfectly suited to controlling power loads in automotive applications, where it improves the overall efficiency of the system by reducing the need for hardwiring. Furthermore, the device is also capable of controlling loads up to 5 times its rated current, making it an ideal choice for applications with high power demand.

The AQV259AZ is also suitable for controlling 230 VAC medium loads, such as electric stoves and hot air furnaces. The device can be used both as a switching device and as an electromagnetic interference (EMI) filter. This makes it the perfect choice for residential and commercial purposes such as powering up electric motors, fans, washing machines, and other electrical appliances.

Working Principle of AQV259AZ

At its core, the AQV259AZ is a 3-way SSR that uses a triac power semiconductor to control the load current. This device controls the amount of power that can be supplied to the load. As a result, it is capable of controlling currents anywhere between 15 and 25 amperes.

The AQV259AZ works on an On-Off principle. When the device receives an input voltage, the triac inside it switches the load to either the ON or OFF state. This process occurs very rapidly, as the device has a switching time of only 2-4 milliseconds. Furthermore, it also has an adjustable zero-cross function, allowing it to switch the load at a predetermined time to reduce electromagnetic interference (EMI).

The AQV259AZ also has a thermal protection feature that prevents it from overheating. This feature ensures that the device can operate without any risk of failure for long periods of time, even when it is exposed to extremely high temperatures.

Overall, the AQV259AZ is an ideal choice for applications where controlling loads is a priority. With its adjustable zero-cross function and thermal protection, it is a reliable and efficient device that can be used in many industrial applications.
