400Hz 항공 지상 전원 공급용 부하 박스

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.

제품 특징

Power ratings available: 90 kW, 120 kW, and 150 kW; multiple specifications are offered.
Equipped with a standard aviation PJ socket as the load input interface; the input technical parameters are: three-phase AC four-wire system, line voltage 200 V, phase voltage 115 V, and frequency 400 Hz.
Equipped with a high-brightness LED display featuring digital display functions for phases A, B, and C, as well as voltage, current, frequency, power, and power factor;
Features a three-phase phase sequence indicator and a phase mismatch warning.
Equipped with EF signal detection functionality to detect the interlocking power supply function of the power source;
Portable: compact in size, lightweight, and can be carried by a single person;
The system must be equipped with a black box module that can monitor data on the data bus during the operation of the load equipment, analyze this data, and extract information such as voltage, current, temperature, gear position changes, and fault details, which are then stored in a dedicated module; this facilitates subsequent data tracing, similar to the black box found on aircraft. In the event of a device failure, this module enables effective determination of whether the issue stems from a problem within the load itself or is caused by an external test power supply exceeding the load’s tolerance threshold, thereby providing a critical reference for troubleshooting.
