Triol AT27 VFD, 10 kV, maximum output voltage 3-10 kV, block-box type

Block-box version of Triol АТ27-6kV variable-frequency drive includes the most up-to-date technical solutions and optimized operating algorithms. Such a design significantly simplifies installation, commissioning and maintenance of medium-voltage drives, wherein no additional construction documents or expert examination is required for onsite installation

  • Low cost installation container enclosure.
  • Outdoor in any climate.
  • Easy maintenance in any weather.
  • Operating temperature range from –60 °C to +50 °C.
  • Easy to integrate into the technological process due to wide range of algorithms and functions:
  1. Triol «Cascade» system;
  2. Flying start of the motor;
  3. PID – regulator;
  4. Operation by calendar settings;
  5. Automatic restart.
  • High overload capability – 120 % in 120 s.
  • Withstands up to –35 % voltage dips.
  • V/F, speed or torque control options.
  • Automatic maintenance of a certain technological parameter.
  • Low harmonic distortion of the supply (THDi).
