Static Frequency Converter

Product introduction

Product Introduction

This series of products adopts power electronic conversion and intelligent control technology. It’s a high performance power supply designed for the ground power supply of aircraft air-borne equipment, and electronic and electrical equipment testing.

Applications

It’s mainly suitable for large aircraft and airborne equipment, radar, navigation and other 400Hz power supply requirements. It is the replacement of traditional generator variable frequency power supply products. The users are aeronautical research laboratories, military factories, troops, civil aviation and other customer groups. This power supply is used in laboratories, electrical workshops, measurement testing lab, aircraft hangars,parking apron,etc.

Main Features

1. Independent three-phase design, each phase can be adjusted separately;

2. Automatic cable voltage-drop compensation function;

3. High brightness LCD display, optimized man-machine interface, simple operation;

4. The output intercepting function can adapt to the impact load starting requirements;

5. Adopts the high frequency switching technology, multi-loop control, with high quality output waveform, good response time and dynamic characteristics;

6. Power-on self-test function to ensure the stable and reliable operation process

7. The superior overload capacity design to meet the requirements of different loads;

8. The optimized air duct design improves the heat dissipation capacity of the power supply, reduces the loss and extends the product lifetime.
