Triol AT24 VFD Line H (660 V), metal enclosure, IP54 protection degree, from 75 to 1200 kW

Triol AT24 VFD Line H provides an easy and functional control of the pumps. It can be used both individually and in various integrated control systems when installing additional communication units. Extensive features provide effective protection for the entire «VFD – electric motor» system.

  • Close-loop speed or torque control;
  • Open-loop speed or torque control;
  • Powerful and reliable solution for high-performance engines;
  • Possibility of VFD’s installation in the engine compartment not using cabinets;
  • Pump language (°C, Pа, Atm, Hz);
  • Built-in PID-controller;
  • U/f control;
  • Multipump and cascade control;
  • Comfortable removable control panel;
  • Protection against unauthorized access.
