Solid State Relays (SSRs) are electrical switches which are activated with an electrical pulse. There are many different types, and they are used in applications ranging from industrial automation to home automation. The G3RZ-201SLN DC12 is one such SSR. This article will discuss the application field and working principle of this SSR.

Application Field

The G3RZ-201SLN DC12 is designed for use in applications such as appliances, computer systems, lighting control, and HVAC. It is a high power relay, capable of handling up to 3600W at 480Vac. It is designed for momentary operation, with a maximum on time of 15 seconds and a maximum off time of 1 minute. It is also capable of handling up to 15A when used with small loads such as LEDs.

Additionally, the G3RZ-201SLN DC12 has several features that make it suited to a variety of applications. Firstly, it is UL and cUL certified, ensuring high safety and reliability. It also has a flicker-less turn-on to reduce noise and reduce the risk of electrical interference. Furthermore, it is designed to be resistant to ambient temperature swings, making it suitable for use in both hot and cold climates.

Working Principle

The G3RZ-201SLN DC12 is an optically isolated SSR, meaning it uses an internal LED to detect whether the circuit should be open or closed. When the control voltage is present, the LED turns on, and current passes through an optically isolated bridge. This bridge passes current to the output contacts, causing them to switch into the closed position.

The SSR also contains other components such as a varistor, snubber, and over-voltage protection. The varistor is designed to reduce variations in voltage, while the snubber improves the DC characteristics and reduces contact bounce. The over-voltage protection helps to reduce the risk of overload, ensuring that the SSR will not be damaged by over-voltage conditions.

The G3RZ-201SLN DC12 is also designed to be resistant to surge voltages. This helps to reduce the risk of electrical damage and failure in applications prone to power fluctuations. Additionally, it has a built-in current limiting device, which helps to protect the relay from short-circuits or overloads.

Conclusion

The G3RZ-201SLN DC12 is a high-power SSR designed for use in a variety of applications. It is UL and cUL certified, and is capable of handling up to 3600W. It has several features such as flicker-less turn-on, varistor, snubber, and over-voltage protection, which make it well suited to many applications. Finally, it is designed to be resistant to surge voltages and contains a current-limiting device to protect against overloads.
