TheGalaxy Controlleris the state of art; latest technology Microprocessor based controller designed for AC Geared & Gearless Elevators for Speed upto 1.5m/s and best suited for low to high rise installation in buildings catering to residential apartments, commercial buildings and hotels.

TheAUTOMATIC RESCUE DEVICEis the safest automatic elevator evacuation device designed for VF Elevators. The Automatic Rescue relates to a new concept and design and operates the elevator controller at rated voltage to perform the evacuation operation.

Principle of Operation

The Automatic Rescue works on the principle of powering and operating the Elevator Controller at rated Voltage to perform the Rescue operation. The Rescue device interfaces with the ES Drive which has a unique feature of "Low voltage DC operation" to operate the Elevator Motor with Low voltage Battery.

The Automatic Rescue comprises of two-phase space vector modulated inverter and a state of the art high frequency battery charger with four operating modes of charging.

During Mains power ON, it monitors the power and continuously charges the Batteries. In the event of power failure, the Rescue device will activate within the predetermined "response time 8 second It will be changeable as per requirement of time. The Powerful Inverter will produce and supply 2-Phase, 400V, sinusoidal power to the Controller. The Controller is now energized with 2-Phase power and will run the Motor as per the controller command direction at low speed and bring the Elevator to the immediate next floor and opens the door automatically. Upon opening the doors, the trapped passengers shall exit and the Rescue will shut down within 9-10 second the Inverter to prevent any further battery drain. When normal power resumes, the Automatic Rescue will automatically switch over the Controller to Normal Operation.
