Solid State Relays (SSR) are electronic switching devices used to switch a device off and on. They are both faster and more efficient than traditional mechanical or electromechanical relays, and they are commonly used in a wide range of industrial and commercial applications. In this article, we will take a look at the CWD2490S SSR and its application field and working principle.

The CWD2490S is a dynamic solid state relay designed for medium-to-high switching speeds and excellent current carrying capacity. It provides reliable, zero-loss switching action and has high input-to-output isolation. The device contains two high-speed TRIACs as its switch elements, making it ideal for controlling loads with high inrush current or switching at high frequency. It is widely used in motor control applications, such as turning a fan on and off, controlling speed, reversing the rotation direction, and so on.

The CWD2490S has an input current rating of 4.5mA and an input voltage range of 3-32 VDC. It is capable of switching currents up to 24A, and has an output with a voltage range of 90-480VAC. It is also equipped with an LED indicator to provide visual indication of the SSR’s status. It has UL, PSE, and TUV certifications, so it is suitable for use in a wide range of industrial and commercial applications.

The working principle of the CWD2490S is based on the TRIAC switching principle. The input of the relay consists of two terminals, A1 and A2, where a control signal is applied. This control signal is translated into an AC waveform by the on-board TRIACs. This AC waveform is then sent to the output terminals, B and C, which are connected to the load. The AC waveform open or closes the contacts of the TRIACs, thus allowing current to flow through the relay.

The CWD2490S is a versatile and reliable solid state relay with high current carrying capacity. It is suitable for use in a variety of industrial and commercial applications. It is capable of switching up to 24A and offers excellent input-to-output isolation. With its UL, PSE, and TUV certifications, it has become a popular choice for motor control applications, and is becoming increasingly used in other applications as well.
