Variable Frequency Drive Triol AT24 SD

Complete cabinet Variable Frequency Drive Triol AT24 SD is designed for controlling different eclectic drives. With degree of protection IP54 and rated motor power from 55 kW to 1 mW, Triol AT24 SD is ready to face any challenge. This drive operates as a separate unit and easily integrates into various control systems as well and meets all the international VFD requirements for general industrial application.

  • acceleration and braking at the set pace;
  • reverse;
  • acceleration, deceleration, stop;
  • protection of the motor against short-circuit currents, overload;
  • control of the electric motor from external two- and three-wire sensors;
  • preservation of motor management configuration;
  • dynamic braking of the motor;
  • management of five pumps at the same time (macro "cascade controller);
  • automatic control of technological processes on the principle of a closed system with built-in pid controller;
  • automatic restart after a power failure, as well as user-configurable special electric drive failures.
