Variable Frequency Drive Triol AT27 ED

Variable Frequency Drive AT27 Energy Drive is a compact cabinet type drive that has a wide range of functionality, various operating conditions and can be used in different segments of industry.

  • optimal weight and size characteristics;
  • allows a compact arrangement due to one-sided maintenance design;
  • a high overload capacity of 120% for 120s, 150% for 3s, 200% for 10ms;
  • working capacity at voltage sagging up to 45%;
  • provides a low level of total harmonic distortion of the input current (THD <5%);
  • remote switching of cabinets;
  • option for bypassing power cells in case of failure;
  • built-in protection system against overload, breakage and short-circuit of the motor phases;
  • provides scalar and vector control;
  • ensures the safety of personnel;
  • systems of mechanical and electrical interlocking completely exclude the possibility of electric shock to personnel during operation and maintenance;
  • has a logical controller that has a built-in optional cascade control function.
