STEP AS380 Machine Room Less Control Cabinet
STEP AS380 Machine Room Less (MRL) Control Cabinet is the ultimate solution for modern architectural designs that prioritize space. By eliminating the need for a traditional machine room, this integrated system allows the elevator’s “brain” to be installed directly within the shaft or in a slim, landing-side cabinet.
Combining the world-class AS380 inverter and logic controller into one high-density unit, this cabinet offers a seamless, high-speed travel experience while significantly reducing construction costs.
Core Advantages of the AS380 MRL
-
Integrated Space-Saving Design: Engineered specifically for MRL applications, this cabinet has a remarkably thin profile that fits into tight spaces without sacrificing cooling efficiency or performance.
-
Whisper-Quiet Operation: Advanced noise-suppression technology ensures that even when the controller is located near living or office areas, it operates with minimal acoustic impact.
-
Intelligent Dispatching: Utilizing high-speed CAN bus communication, the system optimizes traffic flow for single lifts or groups of up to 8 elevators, keeping wait times at an absolute minimum.
-
Green Efficiency: Features low-power standby modes and optimized energy conversion, helping your building meet modern environmental and sustainability standards.
Safety Without Compromise
The AS380 MRL cabinet doesn’t just save space—it sets the standard for passenger protection:
-
UCMP Compliance: Fully supports unintended car movement protection, ensuring the car stays locked in place whenever the doors are open.
-
Accurate Leveling: Advanced sensors ensure the car stops perfectly flush with every floor, eliminating trip hazards for passengers.
-
Rapid Diagnostics: The on-board digital display allows technicians to view fault codes and system status in real-time, making maintenance faster and more accurate.
