Features of HE1000 Series Vector High Voltage Inverter

Feature 1: Three Control modes 

1, High performance V/F control. (Fans, Pumps, Air compressors, etc).

2, Open loop vector control. (Belt conveyer, mill drive, fibrizer crusher, etc.)

3, Close loop vector.  (Applicable to internal mixer, hoister machine, etc.)

Feature 2:Multiple types of motor drives 

Support Asynchronous motors 

Synchronous motors (Include PM synchronous motors) 

Feature 3:Four-Quadrant Drive 

Power units use IGBT for rectification, dual-energy flow, energy-saving and environmental protection. 

With full rated power energy regenerative ability. 

Feature 4:LVRT Low Voltage ride through 

Wide voltage anti-interference capability. The system has AVR function for stable system output when the bus voltage fluctuates frequently. 

No stop when instantaneous power off, during running, the system will not stop after power off in the set time. Can be set when power off 0-5s. 

Feature 5:Full Brand Speed Tracking 

Accurate tracking in the current rotating speed and direction of the motor without installing speed sensor

Automatic starting when power off in the set time 

Feature 6:Multiple unit bypass modes 

The same level bypass, when one unit is invalid, bypass it and continue to run 

Neutral point drifting bypass, CPU smart calculate to ensure output stable and balance

Feature 7:Excellent Low-Frequency Control 

Advanced dead area compensation technology, good low-frequency waveforms; Optimized algorithm of low-frequency oscillation suppression, no motor resonance 

Feature 8:Master-slave control mode 

Multi-motor drive system, realize multi-motor coordination control and obtain power balance. 

Flexible grid connection, support 1 VFD drive more motors. 

Optical loop connection, max support 16 motors in master-slave system. 

Feature 9:Heat Dispersion Simulation   

With advanced heat simulation technology, high reliable structure design for heat dispersion.

System and cabinet use unique air flue, reduce dust accumulation.

PCB/PCBA duel sides covered with conformal coatings, excellent corrosive property to raise IP level.
