450kVA variable frequency ac power supply AC60-334500

1. Rating input voltage: Input power supply is 380V/50HZ factory electricity.(The AC voltage is allowed to range from 323V to 528V )
2.Rating output voltage: we can supply many single phase/triphase grades according to the requirement of the clients.  
3. Rating output frequency: 60HZ/50HZ(can change freely) or400Hz 
4. The precision and output voltage stability:  The allowance of the output frequency≤0.01Hz, stability

5. The stability of the output voltage: static state

6. 50%load output voltage transient changes : 
7.variable-frequency power sources overload capacity:150% 10minutes, 200% 10s    
8. Output voltage wave THD:THD≤1.2~2.8%
