This section specifies the adaptability verification test method for single-phase AC 115V, 400Hz electrical equipment to aircraft power supply systems. This section is applicable to the power supply adaptability test (hereinafter referred to as the power supply adaptability test) for single-phase AC 115V and 400Hz electrical equipment in aircraft systems with power supply characteristics that comply with the provisions of GJB 181B-2012. The power supply adaptability test of single-phase AC 115V, 400Hz electrical equipment in aircraft systems with power supply characteristics that meet the requirements of other standards or specifications can be used as a reference. Note: Given that the requirements for 115V and 400Hz AC power supply characteristics in GB 181A-2003 are completely consistent with those in GB 181B-2012, this part is also applicable to the power supply adaptability test of single-phase AC 115V and 400Ez electrical equipment in aircraft systems with power supply characteristics that comply with the provisions of GJB 181A-2003. There is a significant difference between the 115V and 400Hz AC power supply characteristics specified in GB 181-1986 and GB 181B-2012. It is recommended to refer to the provisions of this section in model development to propose corresponding power supply adaptability test requirements and methods. 2 Normative References: The clauses in the following documents become the clauses of this section through reference in this section.
