• Frequency converter can be self-started, kinetic energy buffer;

• Time is load dependent and has been verified by a third party.

• Currently increased to level 16;

• The stability of medium and high voltage frequency converter is improved;

• Greatly reduce unit IGBT failures due to high frequency control;

• Make the equipment much more stable than standard equipment.

• Adopt mechanical bypass control technology;

• Each phase supports up to 2 bypasses;

• The same level bypass is recommended abroad.

• Fan condition monitoring and alarm;

• The frequency converter can operate normally even if the fan is damaged;

• Frequency converter can accurately locate fan faults.

• Frequency conversion hot backup;

• Improve the reliability of equipment operation;

• When a single frequency converter fails, the motor can continue to run;

• After the fault converter recovers, switch back to parallel operation without stopping.

• Adopt self-developed high-performance speed vector control mode, without speed sensor;

• large starting torque;

• Strong resistance to load fluctuation;

• High control precision.

• Realize free switching from power frequency to frequency conversion;

• Adaptive, no impact during synchronization;

• Support synchronous grid-connection and vector backcutting control;

• Solve the soft start and back switch speed regulation problems of high-power motor.

● Multi-machine master and slave control;

● Power balance distribution;

● Suitable for belt conveyor and other multi-machine linkage field.
