400Hz aviation ground power supply load box
This device is primarily used for 400 Hz load testing in airports, terminals, aircraft manufacturing facilities, and military generator applications. It is designed to test load-carrying products for 400 Hz, 800 Hz, and 1200 Hz intermediate frequency power supplies; featuring a compact size and lightweight design, it is highly portable and an ideal tool for airport and field testing scenarios.
Airport ground static power supplies or jet bridge power supplies, as well as test power supplies from aircraft manufacturers, are indispensable for ensuring the smooth operation of flights; however, 400 Hz medium-frequency static power supplies may encounter issues such as insufficient power output, normal behavior under low current conditions, or abnormal behavior under high current conditions. Therefore, the acceptance testing and maintenance of 400 Hz power supplies require the use of dedicated load equipment; our company has specifically designed and manufactured a portable 400 Hz load box for this purpose.
