Triol AT24, Line 3 (HVAC) application, 380 V/480 V/660 V/690 V

Triol AT24 VFD Line 3 is specially designed for heating, ventilation and air conditioning systems. Metal enclosure with IP20 protection degree allows avoiding VFD’s installation in the boxes and long cable routing. A large number of security and service functions makes this VFD multipurpose solution.

  • Overload capacity is 120 % from the nominal rate during 60 sec;
  • Close-loop speed or torque control;
  • Open-loop speed or torque control;
  • EMC filter C2 category allows to install in the electrical room close to the testing and automation facilities;
  • Low noises level;
  • Ambient temperature -20…+50 °C;
  • HVAC language (°C, Pa, Atm, Hz);
  • Integrated PID-controller;
  • Removable control panel;
  • Special HVAC functions (motor drying, energy saving calculation).
