Features & Details
Key Benefits
-
Security
Our system is equipped with enhanced multi-level protection methods, including overvoltage, undervoltage, overcurrent, and short-circuit protection. With an ultra-fast emergency signal response time of under 30 milliseconds, we ensure the safety of both people and goods even in high-frequency, high-traffic environments. -
Efficient
Our system offers adjustable speeds for flexible, high-cycle operation. The R4 series is optimized for rapid opening/closing, supporting a rated output speed of 133RPM and a maximum lifting speed of 1.95m/s, significantly improving throughput in busy logistics and industrial areas. -
Accurate
We’ve achieved precise control over position, speed, and torque with a fully closed-loop servo system tailored for roller door mechanisms. Our high-precision electronic limits ensure there’s no deviation, even after tens of thousands of cycles. -
Less Impact
The system operates ultra-smoothly without any shaking or jitter, minimizing mechanical impact on the door curtain, guides, and balance components. This drastically reduces wear and tear, extending the service life of the entire door system. -
Stable
Our integrated design includes robust EMC electromagnetic compatibility features, built to withstand the electrical noise common in industrial facilities. We continuously monitor motor output data in real-time, allowing us to assess the status of balance systems like torsion springs and detect any jamming point early, before it causes downtime.
