Frequently Asked Questions (FAQs)

Frequently Asked Questions About 400Hz Factories in China

What is a 400Hz Ground Power Unit (GPU) and why is it necessary for aircraft?

A 400Hz GPU is a piece of ground support equipment that converts the standard 50Hz or 60Hz power to 400Hz, which is the frequency required by aircraft systems. You need this unit because aircraft cannot use the domestic power frequency while on the ground, and the GPU helps in powering the aircraft’s systems efficiently without running the engines or the auxiliary power unit (APU).

How do 400Hz GPUs benefit airport operations and the environment?

Using a 400Hz GPU is very energy efficient and beneficial for airport operations. It eliminates the need to run the aircraft’s engines and APU, reducing noise, air pollution, and unnecessary fuel consumption. This also contributes to lower maintenance needs for the APU, generators, and batteries, making it a more sustainable option.

What are the key features and specifications of 400Hz GPUs from Chinese manufacturers?

Chinese manufacturers like Shanghai Chidge Industries and Lingfran offer 400Hz GPUs with advanced features such as solid-state IGBT/PWM technology, pure sine wave output, and high accuracy in voltage and frequency. These units are available in various power ratings (from 500W to 2000KVA), can be configured for indoor or outdoor use, and come with multiple protection mechanisms against overvoltage, overcurrent, and short circuits.

Can 400Hz GPUs be customized to meet specific requirements?

Yes, many Chinese manufacturers offer customization options for 400Hz GPUs. You can request specific configurations, such as different power ratings, mounting options (fixed or mobile), and environmental specifications. This ensures that the GPU meets your particular needs, whether it’s for airport operations, maintenance hangars, or military airfields.

What kind of quality and safety standards do Chinese 400Hz GPU manufacturers adhere to?

Chinese manufacturers of 400Hz GPUs adhere to strict quality and safety standards. These units are built to meet international standards such as IEC and EN, ensuring high performance, durability, and safety. The manufacturers also implement rigorous quality control measures to guarantee the reliability and efficiency of their products.
