In-situ tester for power supply performance of airplane telex system

The utility model provides an airplane telex system power supply performance in-situ inspection tester, and belongs to the technical field of aviation maintenance. The tester comprises a voltage-frequency measuring meter, a control conversion board, an interface board, an adapter cable and a shell. According to the utility model, the automatic measurement and display of 36 paths of signals of the four-redundancy power supply assembly are realized, and the device can be used after being connected with an adapter cable without being connected with an external power supply for power supply. According to the power supply performance detection, the detection efficiency is improved, and the labor intensity is reduced. After the detection equipment is used, manual on-board detection links are reduced, human errors in testing are effectively reduced, and the risk of short circuit during product testing is avoided. 本实用新型提出一种飞机电传系统电源性能原位检查仪，属于航空维修技术领域。该检查仪包括电压-频率测量表、控制转换板、接口板、转接电缆和壳体。本实用新型实现了4个余度的电源组件共36路信号的自动测量和显示，该设备
