It also integrates more than ten types of electrical parameter measurement monitoring, more than 140 fault diagnosis and protection functions, fully meeting the outdoor IP55 protection level, The ultra wide operating temperature range of - 40~60 ºC, good electromagnetic compatibility, etc. is a safe, reliable, efficient and pure ground static power supply for high-end aircraft. Suitable for airport and aircraft manufacturing, testing, maintenance and other applications.

 Product Functions
400Hz sine wave voltage output
The intermediate frequency power supply has good output characteristics. The total harmonic content is less than 2%, and the voltage modulation amount is less than 1.0% (typical<0.5%).

Output line voltage drop compensation
Compensate the voltage drop of the output cable to ensure the input voltage of the aircraft power supply.

Interlocking power supply function
Users can set the interlocking power supply function to enable or bypass on the settings page.

Built-in protection circuit
Having input overvoltage and undervoltage; Output overvoltage/undervoltage, output overload, short circuit; Aircraft interlocking power supply protection; Various protections such as overheating protect the safety of power supply and user equipment.

Fault detection function
At any time and state of operation, the system performs a self check cycle to check the internal working parameters of the system. If it is not normal, the system will report a fault.
Equipped with comprehensive fault indication functions, users can quickly find the cause of alarms through fault codes.
