Summary: This Chinese standard applies to Uninterruptible power supply (UPS) suitable for installation in the following places UPS: UPS or single interconnected by a number of UPS units with associated controller/switch device structure consisting of a single power supply UPS system, connected to the industry, residential, commercial and light industrial low-voltage power supply system operator can reach any area or separate electrical sites. The following definitions are intended as part of the Class C1, C2 and C3 class products placed on the market before the EMC product standard conformity assessment. C4 type of equipment as a fixed installation process. Use spaces are usually in their final installation check. Sometimes part of the installation is completed prior to inspection. See Appendix E. Selection of these requirements is to ensure the UPS in public or industrial sites has the appropriate level of electromagnetic compatibility. However, these levels can not be covered in any place can happen, but the probability is very low extremes. This standard considers the physical size of the UPS and power ratings ranging from the different experimental conditions. As a standalone product, UPS units or UPS system should meet the relevant requirements of this standard, but should not consider the user to connect the output of the UPS device any load generated by EMC phenomena. This standard does not cover the special installation environment, but also does not consider the UPS fault conditions. This standard does not cover the DC -powered electronic ballasts or on rotary unit UPS. This standard provides: EMC requirements, test methods, minimum performance level.

6.1 Overview This section relates to harassment 0Hz ~ 1.0GHz frequency range. The purpose of determining the emission requirements is to ensure the normal operation of the UPS, resulting not reach harassment interfere with the normal operation of other equipment degree. Note 1. When the class 10m C1 or C2 class UPS receiving antenna distance, 30m C3-based UPS provided with distance, this part can not be sufficiently guaranteed limit Radio and television reception interference. Note 2. If the UPS devices in the vicinity of the high sensitivity, inhibition may have to take additional measures to make the electromagnetic emission is further reduced to a predetermined level. 6.2 General requirements UPS should meet emission limits specified in 6.4 and 6.51). 1) and 6.3 of this article, the original mistake many as 5.3, 5.4. UPS should be tested under the following conditions. --- rated input voltage; --- operating in a normal mode of operation and storage operation mode; --- UPS can access maximum disturbance level of linear load. 6.4 purpose is to within predetermined limits and measurement methods related to the scope of this electromagnetic emission, which can emit electromagnetic other settings Preparation of (e.g., radio receiver) is disturbed. These emission limits are essential electromagnetic compatibility requirements. Test requirements are specified for each port. See Appendix A. Test Method 6.3 general measurement conditions 6.3.1 Overview Maximum emission measurement the EUT should be generated at frequency band and in accordance with normal working state detection applications, UPS work GB 7260.2-2009/IEC 62040-2.2005 As. normal mode and storage mode of operation. By changing the maximum emission test test arrangement UPS. With respect to the additional power source terminal (port) as a stationary bypass circuit and/or maintenance bypass circuit independent power supply UPS, whenever possible, it These additional power supply terminals (ports), should be properly connected to the AC input port of the temporary power supply. 6.4 conduction emission tests should include these Measuring additional circuit. If UPS is part of the system, or may be connected to the auxiliary device, the UPS must simply connect the use of the test ports Minimum assistance device, or equivalent port impedance termination. UPS AC output terminal connected to the linear load can be run under any load conditions in rated output range. Test description should be precise arrangement and mode of operation, the test and measurement arrangement of the guidelines when measured in the test report Appendix A, field test See Appendix E. Should, be tested at its rated input voltage is within a predetermined range of UPS runtime environment, unless otherwise indicated. 6.3.2 the buyer, user files a) If in order to achieve compliance and the need to take special measures, it must inform the buyer, user, for example, the use of shielded cable or dedicated Cable, any limitations should be described in detail in the AC output cable length; b) the buyer user needs document should be sent on the letter, and the list of auxiliary devices UPS emission requirements should be performed together with the file provide. 6.3.3 Applicability Measured at the relevant port UPS. 6.4 conduction emission 6.4.1 supply terminal disturbance voltage limit According to the type and the rated output current of the UPS should not exceed the limit disturbance voltage table 1 or Table 2.
