12 V Solid‑State Relay – High‑Speed, Reliable Switching

Designed for precision control in low‑voltage automation, the 12 V solid‑state relay (SSR) delivers fast, noise‑free switching by employing silicon‑controlled rectifiers (SCRs) or triacs. It offers electrical isolation between control and load sides, eliminating mechanical wear and ensuring long‑term reliability even in high‑frequency applications.

With a compact board‑mount form factor, the relay supports up to 30 A at 30 V AC or 10 A at 30 V DC, making it ideal for commercial HVAC, lighting, motor drives, and industrial process control. Its hermetically sealed construction provides robust protection against dust and moisture, while the internal zero‑crossing design minimizes arc flash and reduces electromagnetic interference.

• Key Spec 1: 12 V DC control input, 0.5–300 V DC/AC output
• Key Spec 2: 10 A continuous load at 30 V DC / 30 A continuous load at 30 V AC
• Key Spec 3: Switching speed 0.2 ms, isolation voltage 5000 V
• Common Use Case: Control of HVAC compressors, LED lighting ballast, or small AC/DC motor drives from a low‑voltage PLC or microcontroller.
