3 phase online low frequency iverter 40K

3 phase online low frequency iverter 40K CDD Low Frequency 3phase in / 3 phase out 10 kva - 500 kva N+1 Redundancy Parallel Array   Chadi CDD series are the double conversion on-line UPS of three-phase inputs and three-phase outputs, ranged capacity from 10KVA~500KVA. This serial UPS apply dual DSP (Digital Signal Processor) controlled technology, and the 6th generation IGBT and static switch with low loss and high power.     Main Feature:
•DSP full digitalized control
•comprehenvise pretection  
•enviromental protection and energy-saving
•friendly computer-human interface   
•Superior loading characteristics
•High power dynamic performance
•Auto re-start function
•3-phases control seperately   
•Self-diagnose
•super wide input voltage range
•optional   
•3-proof technique
