Product Description

Aircraft ground static power supply
Product introduction
The aircraft ground static variable power supply is a 400Hz AC power supply equipment specially developed for the airport, airline, aviation industry department and army for the ground power supply needs of aircraft and airborne equipment by our company with the latest power electronics and intelligent control technology. The products can be widely used in boarding bridge, apron, hangar, accessory workshop, laboratory and other places, with the advantages of good waveform quality, small volume, light weight, low noise, no pollution, low operating cost, etc.
Technical features
-  The leading parallel and redundancy technology of multi machine power supply without master-slave directly breaks through the bottleneck of capacity expansion and improves operation reliability.
-  The instantaneous waveform tracking control technology makes the output voltage harmonic, phase voltage modulation and dynamic characteristics reach the international advanced level.
-  Unique current real-time control and interception technology, fully suitable for motor and rectifier impact load.
The three-phase voltage decoupling control technology can adapt to any unbalanced load.
-  12 pulse rectifier transformer and rectifier components can reduce the harmonic current injected into the power grid and reduce the impact on the power grid. APF module can be selected, and the harmonic of the input current is as low as 5%.
-  It has the advantages of advanced technology, high safety, modular design, light weight and good maintainability.
-  The latest generation IGBT module realizes high-power converter, with standard power level of 180KVA and maximum field operation capacity of 450kva, which is the most in the industry.
-  DSP intelligent monitoring, VFD fluorescent Chinese display and external control / communication interface, convenient operation.
-  It can provide up to 30 kinds of self diagnosis information, and the fault can be directly located to the original part, which is convenient for maintenance.
