FRENIC-LIFT
Elevator Inverters |
|
 |
Welcome to the new generation of LIFT and ELEVATOR inverter
The Frenic Lift Series of exclusive inverters for operation of elevators are specially designed to have a number of improved features over previous elevator inverters, such as vastly lower torque ripple. We have incorporated the functions that customers find most necessary in elevator controls to provide an inverter that delivers performance that fits your elevator system.
- Optimum exclusive design for passenger elevators
- Higher performance
- High performance vector control
- High overload capacity
- IM/PMSM common drive
- Model variations
- Applicable to the feedbacks from various pulse generators
- Maintenance functions/ Long life design
- Globalization
- Peripheral support tools
