SCR08/1100G DC motor speed controller is a low-cost, mature and reliable product with high speed regulation accuracy. It is suitable for mechanical equipment that needs to be adjusted in papermaking, rubber, food, printing, metallurgy, etc.
The SCR-08/1100G is a controllable silicon (SCR) based DC motor speed controller designed for applications such as paper making, rubber, food processing, printing, and metallurgy. It offers low cost, reliable technology, and high speed regulation accuracy.
Key features include step‑less speed control via SCR triggering, voltage negative‑feedback for smooth operation, over‑current protection, soft‑start to limit inrush current, and an isolated photo‑electric eye interface. The manual lists normal operating voltage, current limits, compatible motor power ranges, output voltages, and physical dimensions, and provides a wiring diagram for power input, speed control, motor connection, and photo‑eye integration. This manual is written in Chinese.
