Swift and Secure: The Allure of Rapid Electric Rolling Shutters

Name

Rapid Electric Rolling Shutters

Model

KS-2500MM/S Series

Control System

The Rapid Electric Rolling Shutters is equipped with a specialized control system featuring a DSP processing chip for precise operation:

1. LED display for fault codes.

2. Reverse protection: Stops the door and displays an error if motor drive wiring is connected incorrectly.

3. Three fully closed control loops (torque loop, position loop, speed loop) ensure accurate functionality.

4. Integrated braking capability without external electromagnetic brakes, enabling precise stopping at limit positions.

5. Memory function post-power failure: The system resumes operation directly after power restoration without needing re-adjustments.

6. Overload and overcurrent protection for the motor.

Motor System 

· Type: Senlima Rare Earth Permanent Magnet Synchronous Motor

· Features: Integrated encoder, brake system, large-inertia planetary reducer, and emergency manual opening mechanism.

1. Constant torque output enhances safety devices (e.g., infrared sensors), ensuring rapid rebound response.

2. High overload capacity supports over 1,000 cycles per day in high-frequency applications.

End Buffering System

Utilizing Senlima Motor's constant torque characteristics, the end buffering technology ensures:

1. Smooth operation, minimizing noise during door movement.

2. Effective protection of the reducer and operational mechanisms from rigid damage.

3. Adjustable speed settings (fast-slow-stop), reducing wear and extending the lifespan of components, particularly the reducer.

Lifting Mechanism

Aluminum alloy turbo guide rails, patented technology ensuring high-speed operation.

Multiple installation structures available (standard turbo intake, oval intake, vertical lift, 90-degree turning lift), with standard being turbo intake. Other options require pre-scheduling with sales personnel.

Door Body Structure 

Material: Split assembly structure with insulated aluminum alloy panels, multi-layer sealing strips, silent load-bearing hinges, and polyurethane guide wheels.

· Panel Thickness: Standard 40mm.

· Colors: Gold, white, silver, blue, gray, coffee, etc., per international color cards.

· Wind Resistance: Up to 12 levels

Sealing: Flexible rubber strips between panels, rated for over 1 million folding cycles.

Soundproofing: Load-bearing hinges prevent stress on connections, ensuring long-term flatness.

Guiding System: Polyurethane wheels slide smoothly in aluminum alloy tracks, ensuring high-speed operation.

Safety System

Infrared Safety Photocell:

· Detects obstacles under the door, keeping it open until cleared.

· Rebound functionality to protect objects during descent.

· Configurable sensitivity and functionality via parameter settings.

Bottom Safety Edge:

· Reacts to obstacles missed by infrared sensors, triggering an immediate rebound to prevent accidents.

Wind Resistance:

32 m/s (Grade 12)

Transparency:

Premium polycarbonate panels with a dual-layer design:

· Provides excellent insulation while maintaining transparency and light transmission.

· Clear visibility inside and outside, adding aesthetic value and showcasing modern design.
