CP Series 1/1 phase online UPS low frequency double conversion with intelligent digitization
Capacity for single machine from 1KVA-40KVA:
Stable performance for advanced digital circuit system.Intelligent battery charger,durable and worry-saving.Whole course guardianship for intelligent detection system.Smart communication interface RS232 and remoted monitoring SNMP. The sixth generation IGBT and high-speed static switch shift technology.Direct LCD data display and LED work status display,without difficulties between machnine and human.Machine principle:
The UPS is a multiple proctective uninterruptible power system,with output isolation transformer,double convertion and digitization function.When AC is normal,it will filter the interruption from AC, and change AC rectifier into pure DC firstly, then change DC into pure sine wave AC output by inverter.At the mean time,the battery will be charged.When AC is abnormal,the DC stored by battery will invert to AC to output,guaranteeing the loads can get the high quality power electricity;It will shift to bypass automatically to supply power while the inverter is off or have faults.
