JOSEF Joseph STR-F2-5/125VDC Time Relay Advanced Welding Workshop

Description :

　　The STR-F2 non power start anti-interference time relay is a specially designed relay designed to provide stable and reliable time delay function, while also possessing strong anti-interference ability. The following is a detailed introduction about the relay:

　　Firstly, the STR-F2 time relay is designed as a power on delay relay, suitable for automatic control circuits with AC voltage of 90V~280V and DC voltage of 24V~220V. It can implement power-off delay action in the circuit, providing the required delay for the controlled components. This design enables it to perform excellently in both AC or DC protection and automatic control devices.

　　Secondly, the delay accuracy of the STR-F2 time relay far exceeds that of traditional electromagnetic and RC time relays. This high-precision delay function provides effective support for shortening the time difference between the main protection and backup protection of power system relay protection.

　　In addition, the STR-F2 relay adopts a static integrated circuit, which makes the setting range larger, the step difference smaller, the contact capacity larger, and the setting process intuitive and convenient. Its delay range is wide, with multiple options including 0.3 seconds to 3 minutes, 0.3 seconds to 6 minutes, 0.5 seconds to 30 minutes, and 1 second to 60 minutes.

　　In terms of stability and reliability, the STR-F2 relay uses integrated circuits and imported components to ensure its high performance and long-term stable operation. At the same time, the relay also has strong anti-interference ability, which can maintain a stable working state even in places with strong interference or poor power supply voltage quality.
