Working Principle of DR2220D30U

DR2220D30U is an SSR device based on the principle of resistive heating. Its working principle is based on the self-heating effect of the resistive material in a metal junction. When the relay is energized, an electric current is passed through a resistive material, which starts to heat up the metal junction, which causes the switch to open or close. In order to ensure the reliable performance of the device, DR2220D30U comes with built-in protection parameters, such as over current protection, short circuit protection, and thermal overload protection.

DR2220D30U also comes with a voltage surge protection, which is designed to protect the device against transient currents, making it suitable for use in harsh, wide temperature ranges. In addition, the device also comes with a current cut-off protection feature, which enables the device to overcome potential short-circuit conditions.

Conclusion

As a leading SSR, DR2220D30U is a powerful and reliable switch solution that provides a wide range of features and functions. It is designed to cover the most challenging applications in extreme conditions and harsh environments. Additionally, its adjustable performance parameters, such as over current protection and thermal overload reduction, make it an ideal choice for its application fields.
