Features
Continuous Monitoring
24-Hour Intelligent monitoring of elevator status, ensuring immediate response when needed.
Fast Activation
Rapid automatic start upon power failure without manual input, shortening the rescue time.
Precision Control
Uses a 32-bit microprocessor for controlling rescue operations and signal processing with high accuracy.
Automatic Charging
Includes sealed lead-acid batteries with automatic charge management, which increases the battery life.
Customization
- Power Ratings: Selectable models to match the inverter power of the elevator drive (e.g., 5.5 kW to 30 kW).
- Battery Configuration: Different battery capacities (e.g., 12 V/7 Ah, 12 V/9 Ah) depending on required rescue duration.
- Rescue Time Settings: Adjustable rescue operation period (typically 3–15 min) to fit building height and elevator travel requirements.
- Installation & Integration: Tailored wiring and control interface options to integrate with existing elevator control systems.
