Solid State Relays - GN025DSR Application Field and Working Principle

Solid State Relays provide quick, correctly-oriented switching, of a higher level of performance than traditional mechanical relays. The GN025DSR is a 25A bidirectional, 600VAC/DC solid state relay which is available for a variety of applications.

The GN025DSR’s performance lies in its wide operating temperature range of -20 to +70 degrees celcius, its ability to survive surges of up to 4500 volts, and its compact size (just 22mm x 28mm x 28mm) that allows for easy mounting in harsh environments – even in up to 100 volts of shock protection. This makes the GN025DSR ideal for many industrial and heavy-duty applications, particularly where reliability is key.

Applications of the GN025DSR

The GN025DSR is primarily used in industrial motor control applications. It can be deployed in motors, pumps, fans, and other energy-intensive industrial equipment. It is also well-suited for use in automotive applications, such as starter motors, alternators, and fuel pumps. Additionally, the GN025DSR is suitable for use in communications, audio, prints, consumer durables, and medical applications.

The GN025DSR supports zero-crossing, which improves its reliability and ensures proper electrical system synchronization. Additionally, it has many additional features that make it ideal for many applications. Among these are its robust construction, its ability to handle high inrush current with ease, and its support for up to 25A continuous current.

Working Principle of the GN025DSR

The GN025DSR is a hybrid design, combining silicon controlled rectifiers (SCR), thyristor, and MOSFET technologies. This allows it to support a wide range of loads and accurately switch them on or off depending on the application. The core principle behind the GN025DSR is that a positive voltage is applied to a control pin, which then triggers the switching of the power device.

The GN025DSR is a passive solid-state relay, meaning it has no active drive circuitry and is typically used in a single-ended configuration. This means that it is not able to control other circuits, but instead is designed to switch between two different states in response to the applied control voltage. It also enables switching between zero-crossing (VCC~) or random switching (VCCR) operation.

Installation and Setup of the GN025DSR

The GN025DSR is easy to set up thanks to its plug-and-play installation. A single 240VAC or 600VAC mains line is connected to the relay’s input, then the output is connected to the load. A control voltage is then connected to the relay’s control pin.

After installation, the GN025DSR must be tested to ensure proper operation before full current is applied. It is important to check that the relay is properly connected and that the control voltage is within the specified range. Once the relay is tested and confirmed to be in proper working condition, it is ready for operation.

Conclusion

The GN025DSR is a 25A bidirectional, 600VAC/DC solid state relay designed for industrial and heavy-duty applications. It is fast, reliable, and has a wide operating temperature range. The GN025DSR is capable of switching loads up to 25A continuous current with the assistance of its unique hybrid design, featuring silicon controlled rectifiers, thyristor, and MOSFET technologies. Installation and setup is easy, and it supports Zero-Crossing, which ensures proper operation and higher reliability. In short, if you are looking for a high-performance solid state relay, the GN025DSR is an excellent option.
