Danfosss VLT Lift Drive LD 302 lift series: model LD-302P37K

A modular Danfoss VLT® Lift Drive, with optimised motor control software to control the motor and hydraulic valves, was installed in the existing lift system and cabin, resulting in a faster, more comfortable and energy efficient daily operation. This system has also reduced the operating noise levels of the elevator. Designed for all motors and grid voltages a VLT® Lift Drive solution is suitable for both rope and hydraulic elevators in open or closed loop systems. Fitting all common feedback systems, they are swift to mount and commission with just 10 parameters or less.

• Operates without contactors: No switching noise
• Fans work only when needed. No noise emission when not in use
• Integrated harmonic suppression reactors reduce TV/radio interference
• Reduced panel space due to integrated filter, reactor and brake
• Wall mount: requires no cabinet space, can be mounted close to motor
• Operation without absolute encoders for PM motor
• Operation modes with reduced peak currents for hydraulic elevators
• Inverter efficiency >98% incl. filter and harmonic suppression reactors
• Optimized savings on hydraulic elevators
• Operation modes with reduced peak currents for hydraulic elevators
