标准范围

IEC 62040-3:20 21(E)规定了适用于移动式、固定式和固定式电子不间断电源系统(UPS)的性能和测试要求-由不超过1000V的交流电压供电，-提供不超过1000V的AC输出电压，-结合不超过1500V DC的能量存储装置，以及-具有确保负载功率连续性的主要功能。本文件规定了完整UPS和单个UPS功能单元（如适用）的性能和测试要求。本文件还包括与UPS功能单元相互作用以保持负载电源连续性的UPS开关相关的UPS性能和测试要求。本文档不涵盖-常规AC和DC配电板及其相关联的开关，-IEC 62310-3涵盖的独立静态传输系统，-IEC 88528-11涵盖的旋转式UPS，以及-IEC 62040-5-3涵盖的直流UPS。与上一版相比，此版本包括以下重大技术变更:1)符合IEC 62040-1:20 17（UPS安全要求）的环境条件；2）表5 UPS测试时间表中引用的所有子条款中包含的合规性要求；3)非线性阶跃负载不再是型式试验，并从6.4中删除，以符合包含浪涌电流控制的开关模式电源的要求；这导致性能分类编码从8个字符缩短到7个字符（见5.3.4）；4）符合ISO 4180的自由落体试验（见6.5.1.3）；5）介绍了多种常模UPS测试要求；6）附录E中放宽的非线性负载要求，与符合IEC 61000-3-2和IEC 61000-3-12中谐波电流适用限值的开关模式电源要求一致；7)附录I中引用的最小UPS效率值成为标准值，并且基于有源输出功率额定值和加权系数的利用，而不是基于与隔离变压器、输入谐波电流滤波器和输入电压相关的余量。

IEC 62040-3:2021(E) establishes the performance and test requirements applied to movable, stationary and fixed electronic uninterruptible power systems (UPS) that
- are supplied from AC voltage not exceeding 1 000 V,
- deliver AC output voltage not exceeding 1 000 V,
- incorporate an energy storage device not exceeding 1 500 V DC, and
- have a primary function to ensure continuity of load power.
This document specifies performance and test requirements of a complete UPS and, where applicable, of individual UPS functional units. This document also includes UPS performance and test requirements related to UPS switches that interact with UPS functional units to maintain continuity of load power.
This document does not cover
- conventional AC and DC distribution boards and their associated switches,
- stand-alone static transfer systems covered by IEC 62310-3,
- rotary UPS covered by IEC 88528-11, and
- DC UPS covered by IEC 62040-5-3.
This edition includes the following significant technical changes with respect to the previous edition:
1) environmental conditions aligned with IEC 62040-1:2017 (UPS safety requirements);
2) compliance requirements included in all sub-clauses referenced in Table 5 UPS test schedule;
3) non-linear step load is no longer a type test and was removed from 6.4 in consistency with requirements for switch mode power supplies incorporating inrush current controls; this resulted in the performance classification coding being shortened from 8 to 7 characters (see 5.3.4);
4) free-fall test aligned with ISO 4180 (see 6.5.1.3);
5) multiple normal mode UPS test requirements introduced;
6) non-linear load requirements relaxed in Annex E in consistency with requirements for switch mode power supplies complying with the applicable limits for harmonic current in IEC 61000-3-2 and IEC 61000-3-12;
7) minimum UPS efficiency values referenced in Annex I became normative and are based on active output power rating and utilisation of weighting factors rather than on allowances related to isolation transformers, input harmonic current filters and input voltages.
