1 Scope

This part of GB/T 7260 specifies electronic DC output uninterruptible power supply systems suitable for movable, non-movable and fixed installations:

System (DC uninterruptible power supply) performance and test requirements: This type of DC uninterruptible power supply has the following characteristics:

---Powered by an AC voltage source not exceeding 1000V;

---Provide a DC output voltage not exceeding 1500V;

---Contains an energy storage device;

---The main function is to ensure the continuous DC power supply to the load:

This section specifies the performance and test requirements of a complete DC uninterruptible power supply system (rather than a single DC uninterruptible power supply functional unit):

begging: The performance and test requirements of a single DC uninterruptible power supply functional unit can be found in the IEC publications mentioned in the references, which are in line with this part:

The points are not contradictory:

The power range of DC uninterruptible power supply ranges from less than one hundred watts to megawatts, which can meet the requirements of various loads on power availability and power quality:

Claim: See Appendix A and Appendix B for information about typical DC uninterruptible power supply configurations and topologies:

This part also includes components related to circuit breakers, disconnect switches, and interconnect switches (if any) integrated in the DC uninterruptible power supply:

Performance and test requirements: These components interact with other functional units of the DC uninterruptible power supply to maintain continuous load power:

This section does not include:

---Traditional AC input switchboard and related switches;

---Traditional DC distribution boards and related switches;

---Traditional AC uninterruptible power supply covered by IEC 62040-3;

--- Low-voltage DC power supply equipment covered by specific product standards (e:g: IEC 61204) and specific product standards (e:g: ITU communication standards)

Quasi) covered equipment;

---The output voltage is derived from the system of rotating electrical machines:

Note 1: This section believes that the uninterruptible power supply system is mainly used for the power supply of information technology (IT) equipment: Therefore, the DC uninterruptible power supply specified in this section

The output characteristics are also designed to ensure compatibility with the requirements of IT equipment: This point is subject to the limit range declared by the manufacturer, including the steady-state and transient voltage

Changing requirements and requirements for power supply to IT equipment with both resistive and constant power load characteristics:

Note 2: The test load specified in this section simulates both resistive and constant power load characteristics: The application of this type of load is to verify the

Design and performance, and minimize the complexity and energy consumption in the test process:
