Online double conversion design, zero switching, rack mounting, the preferred product for computer room power supply.

Room

◆ The application of advanced DSP digital control technology makes the performance of UPS more stable and the quality more superior.

◆ The load power factor is 0.8, which is suitable for the development trend of electrical equipment and has stronger load capacity.

◆ Active input power factor correction (PFC), input power factor up to 0.98 or more

◆ Wide input voltage frequency range,extremely wide input voltage and frequency range, adapt to remote areas with very harsh power environment.

◆ Can be matched with generator.

◆ Cold start function.

◆ Zero switching, effectively ensuring the safety and reliability of load operation.

◆ Powerful monitoring, standard RS232 communication interface and intelligent slot, expandable SNMP card, RS485, AS400 card, EMD environmental monitor, etc.

◆ Invisible handle design

◆ Standard rack mount and wall mount installation method are optional
