Variable Frequency Drive Triol AT24 UC

Triol AT24 VFD Line UC is the best solution to increase equipment productivity. This line is characterized by a robust construction, multifunctionality and flexibility. This drive is a great option to ensure smooth operation of equipment, increasing its life period thanks to the flexibility and modernity of the technical solutions.

  • start, stop and speed control of the pump and motor;
  • acceleration and braking at a set pace;
  • reverse;
  • acceleration, deceleration, stop;
  • motor protection against short-circuit currents, overloads;
  • control of pumps from external sensors;
  • preservation of the motor control configuration;
  • dynamic braking of the motor;
  • simultaneous control of five pump motors (macro "Cascade controller");
  • automatic control of technological processes on the principle of a closed system with the built-in PID controller;
  • automatic restart of induction motor after a power failure;
  • operation of induction motor according to a user-defined schedule in automatic or manual mode.
