Why 400Hz?

As we know, the aircraft is using 400 Hz power supply and it is because the higher hertz of the power supply system, the lesser of copper and steel materials of the generator and transformer being used, which lead to light weight and low cost. The disadvantages are the electrical equipment and wiring inductance increase, capacitances decrease, losses increase, reducing the power transmission efficiency. Conversely, lower hertz will increase the use of materials, which lead to higher weight and costs. So, 50 Hz, 60 Hz is an appropriate value for mains power supply, 400 Hz for aircraft, military, vessels, navy ships etc.

Acsoon® AF400W series is one of the most popular static frequency converters. AF400W is designed to change the power at 50Hz or 60Hz to aircraft quality power at 400Hz.

It integrates with IGBT(Insulated Gate Bipolar Transistor) made by Mitsubishi, Siemens, and Infineon, and combines microprocessor made by ACSOON to accomplish quicker response and higher reliability.

So Acsoon ® AF400W as a power source to develop aircraft quality 400hz Power. It has strong adaptability, high stability and stable output waveform and the volume is relatively small. There are mostly used in aircraft production manufacturing, military/civil hangar, maintenance plant, aerospace equipment, military airport tarmac and wells, etc.
