GSR-1 Single Phase Solid State Relay

The GSR1-1 DA single-phase solid state relay (SSR) is a contactless switching device designed using modern microelectronics and power electronics technology. It abandons the mechanical structure of traditional electromagnetic relays and achieves on/off control of circuits through semiconductor devices. It has core advantages such as high reliability, long lifespan, and low interference, and is specially designed for efficient and stable electrical control scenarios.

Product features of GSR1-1 DA single-phase solid-state relay:
1. Wide input compatibility and low current drive:
Supports a wide range of DC or pulse input voltages, requiring only a low control current of ≤ 15mA to drive, simplifying peripheral circuit design.
2. Zero contact loss and long-life design:
There are no mechanical moving parts inside, completely eliminating arc wear, and the theoretical electrical life can reach billions of operations.
3. High speed undisturbed switching:
Adopting zero crossing triggering technology, conducting at the zero crossing point of AC voltage and turning off at the zero crossing point of current effectively suppresses surge current and electromagnetic interference (EMI).
4. Multiple integrated protection:
Built in RC resistance capacitance absorption circuit, effectively absorbing transient overvoltage and surge current at the load end; The fully sealed epoxy resin structure provides IP level protection and is suitable for humid, vibrating, and corrosive environments.
5. Strong electrical isolation:
Optocouplers achieve electrical isolation of up to 2500VAC between input and output, ensuring circuit safety and enhancing system anti-interference capabilities.
