UPS Power Module
DU5000H
The DU series high-frequency online UPS for electric power systems is a power supply product specifically designed to meet the development needs of China's power industry. It features double-conversion online architecture and zero transfer time capability. The UPS does not require its own backup batteries; instead, it shares the battery bank of the existing DC power system (DC UPS). The DC input of the UPS is completely electrically isolated from the AC input and output, meeting the stringent requirements of the power sector. It features a built-in CPU and an independent LCD display.
Product Features
Zero Standby Power ConsumptionWhen the input AC is online, the DC/DC converter at the DC end is in a shutdown state. When the input AC is abnormal, the DC/DC converter at the DC end is quickly activated, achieving zero switching between AC and DC power supply while effectively reducing standby losses at the DC end.
01
Safety & ReliabilityUnlike inverters with two input paths, the DU series UPS has one battery bank and two AC inputs, totaling three input paths. As long as one input voltage is normal, it can ensure uninterrupted power output at the load end, greatly improving power supply reliability.
02
Excellent PerformanceOn the basis of completing the basic functions of an inverter, an additional AC input is added. Through the process of rectification and re-inversion, it forms a high-precision standard 220V sine wave output.
03
Zero-Second SwitchingThe switching between the main AC input and the battery bank can achieve 0ms conversion with absolutely no power interruption time.
