Background
With the thriving aviation manufacturing and maintenance industry, power supply systems utilizing 115V/400Hz medium-frequency AC power and 28.5V DC power are becoming more widespread and their numbers are continually increasing, particularly at civil aviation airports and major aircraft manufacturers. Users require specialized equipment to perform daily inspections of aviation ground power to meet the needs of routine production and maintenance.
Section II: Product Advantages
At user sites, the power supply system directly faces expensive installations of aircraft and aircraft components. To confirm the normal operation of the power supply system, specialized testing equipment is required to check the 115V/400Hz and 28.5V power supply. The system must be normal, portable, and safe. Standard load designs are for 50Hz or 60Hz AC power sources, while 400Hz power sources cannot be measured. If the frequency reduction method is used to test intermediate frequency power sources, the precision testing error will increase. Our company's developed aircraft ground power supply test load is a professional portable aviation test load. The AC load can simulate the aircraft's intermediate frequency 115/400Hz characteristics, while the DC load can simulate the intermediate frequency characteristics of DC 28.5V. It completely replaces aviation connectors on aircraft and对接 power systems, completing a series of tests on the power supply system.
AC Aviation Load Customization Range from 0-140KW AC offers customers a wider range of suitable product options, ensuring completion of full-load tests (full-load capacity), overload tests (load test with overload protection), precision tests of the medium-frequency power system, and other operational tests.36V Aviation Power Supply，400Hz Variable Frequency Power Supply，115/200V Power Supply，27V DC Power Supply，400 Hz power supply，Aviation Power
III. Solutions
The runway is where aircraft are directly parked, demanding stringent conditions and requirements for all equipment, and prohibits the use of equipment with safety hazards. It is recommended to conduct high-power load tests of 90kW or more at open spaces such as airport maintenance facilities and ground handling management areas.
Features of Aviation Exchange Charging
1) Initiate the mid-frequency power supply, activate the EF switch, and the panel displays various parameters.
2) Select the test load for load testing, rotate the knob to achieve 0~6KW step load.
After completing the test, gradually reduce the load to 0 and turn off the EF switch.
4) The medium-frequency power supply is turned off, and the aviation plug is removed. The load itself has no power. The screen display and fan cooling power come from the external power supply system.
