Variable Frequency Drive Triol AT24 RT
Variable Frequency Drive Triol AT24 RT is specially designed for controlling Progressive Cavity Pumps. The solution is developed according to the specific demands and has the following advantages: passive filter; kinetic redundancy; competitive cost price.
- 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.
