Variable Frequency Drive Triol AT24 line LE

Variable Frequency Drive Triol AT24 line LE is designed to control PM and induction lift winch from 5.5 to 37 kW, performed in a plastic or metal case with IP21 enclosure. Working with operating temperature −10…+40 °C, this drive has a built-in seven-segment remote. The line is specially designed to ensure safe and reliable operation of elevator equipment, has advanced functionality for modern elevators, and works with all existing elevator motors, as well as with all known encoder types. Triol unique algorithms of sensor and sensorless vector control, algorithms of a specialized elevator functional, and slip compensation are successfully implemented in Triol AT24 VFD line LE.

In addition, Triol AT24 VFD performs continuous monitoring of the circuit integrity from VFD to the motor, through the control of currents using a special algorithm. Also, the drive is fitted with «evacuation of passengers». You are able to easily setup the drive via Wi-Fi using a convenient interactive application via phone or tablet and many other convenient options that won’t leave you indifferent.
