Triol AT24 37K line C
123456

Triol AT24, Line 1 (Lift, Elevator) application, 380 V/480 V/660 V/690 V

Triol AT24 VFD Line 4 is known for its multifunctional performance and flexibility in such spheres of application as ventilation and air conditioning. Due to its optimal construction this VFD allows realization of a big variety of tasks. This makes the VFD universal solution. This line can be identified by high quality, easiness of access and simplicity of operation.

  • High overload capacity — 220 % during 1 — 2 sec, 150 %during 60 sec;
  • Close-loop speed or torque control;
  • Open-loop speed or torque control;
  • Unique algorithms for hoists control;
  • EMC filter C2 category allows to install the equipment in the electrical room close to the testing and automation facilities;
  • Easy installation at the control cabinet;
  • Support of the absolute and incremental encoders;
  • Compatibility with the lift application VFD’s of the main manufacturers;
  • Measuring motor parameters at stand still (no shaft rotation);
  • Integrated braking chopper.
