Machine: Power Matched with Precision

The Elevonic® Class uses advanced variable-voltage, variable- frequency machines with sophisticated AC drive systems.
The resulting power train:
• Reduces machine size and weight
• Reduces starting current
• Eliminates power-supply line pollution
• Eliminates carbon-brush dust
• Provides an optimum machine drive combination for the duty loads required by your building

The Intelligence of a Great System

Otis’ intelligent Elevonic® controller reduces waiting times, enhances group performance and guarantees the same smooth, quiet ride, regardless of circumstances.

The Elevonic Class of ACVF control systems delivers consistent, precise leveling and optimal ride comfort. Multiple closed-loop functions constantly monitor a car’s performance, measuring every aspect against predetermined standards, and correcting even the slightest deviations within milliseconds.

The Definitive Measure of Performance

Efficient dispatching is key to performance; and the most efficient dispatching systems in the industry are provided within the Elevonic® Class range of products.

The core of the Elevonic Class controller is the RSR Plus® dispatcher—the most efficient in the vertical transportation industry. Its algorithm of bonuses and penalties consistently delivers the shortest waiting times with the minimum number of elevators.

Safety First

Otis has earned, and maintains, the best safety record in the vertical transportation industry. This unprecedented record results from many factors.

Product innovation: Otis works constantly to improve the safety of existing products and to implement new safer technologies.

• A high-tech alloy wedge face for the safety brake shoe, with exceptional temperature, strength and friction characteristics improves braking performance, and reliability in emergency situations
• The HPLIM® door system eliminates pinch points
• The LAMBDA® 3D entrance-protection system prevents doors from striking passengers

Energy Efficient

To promote a cleaner environment, the Elevonic® Class systems use ACVF regenerative equipment whenever possible, to return energy to a building’s electrical grid for reuse. They provide a total power factor that is near unity, resulting in the most energy-efficient elevators in existence.

The gearless Elevonic AC machines further conserve power by reducing initial starting currents, improving drive-train efficiencies and eliminating carbon brushes.

The efficiency of the Elevonic Class system’s dispatchers also save energy by reducing unnecessary starts and stops, resulting in elevators that are environmentally friendly.

These efforts reflect Otis’ corporate commitment to a cleaner and safer environment.
