Frequently Asked Questions (FAQs)
What should I consider when choosing 400Hz frequency converter manufacturers?
Consider product reliability, adherence to aviation and military standards, and post-sale service for the 400Hz power supply systems while selecting the supplier. Make a comparison of the rotary converters, static converters, and available filtering or transformer options for the best possible capacity and amenability to maintenance that suits your use case.
How do aircraft frequency converters differ from industrial 400Hz systems?
The converters used in airplanes focus on being light as well as the robustness of structure, ruggedness, and strict voltage control for avionics and other systems on board, on the other hand, the industrial 400Hz systems usually lay stress on the never-stopping operation, cooling, and the potential to grow. The manufacturers of the light-weight units mostly have the defence affairs or aviation certifications available and they meet local power requirements with their power supply systems.
What are the pros and cons of rotary frequency converters versus static frequency converters?
Rotary converters, despite being more massive and needing a lot of care, promise a valuable advantage – they give out the purest sine waves and have large inertia. Static converters, on the contrary, are not so heavy and are more energy-efficient, with fewer moving parts; nevertheless, they might be in need of an extra filter. The choice between a rotary and static depends on such factors as the extent of harmonic distortion tolerated, the cost involved in the product’s entire service life, and the ease of moving it about.
Can 400Hz frequency converter manufacturers provide portable 400Hz generators for field use?
Certainly, various companies offer the market reasonable 400Hz generators, which can be used in the field and for maintenance purposes in rough containers provided with a detachable transport shock. Such generators often come with all the accessories in-built, such as transformers, filters, and quick-connect interfaces for the airplane’s ground power source.
