FST-700 Medium Voltage Vector Control Frequency speed changer 

7.5kw-1000kw 660V or 1140V three phases

Specifications:
Low inductance design of main circuit

For large inertial and high precision drive control

PG vector control

Production introduction:

Input power: 3 phases AC 660V or 3 phases AC 1140V

Control mode: no PG vector control, PG vector control, V/F control without PG, V/F control with PG

Starting torque: 0Hz 200% with PG vector control(VC); 0.5Hz 150% without PG vector control(SVC)

Soft start and soft parking to heavy load, low start current, stable start speed, small impact to grid

Flexible adjustment to S-curve according to present working conditions, so as to reduce dynamic tension when start

More than 30 types of running control and protection functions, such as over current, over voltage, overload, under voltage protection, short circuit protection, etc.

The expansion board can be selected by customer's request.

 

Application:

Conveyor belt of mine, scraper conveyor, coal feeder, oil pump and electrical submersible pump of oilfields.
