Frequently Asked Questions (FAQs)
What are 400Hz frequency converters?
400 Hz frequency converters are machines that convert the usual voltage of utilities to 400 Hz alternating current power used chiefly in the field of aviation and military. These devices can be rotary frequency converters or static frequency converter systems depending on the application and the manufacturer.
Why do aircraft and military systems use 400Hz power?
Aircraft and military systems use 400 Hz power as they can considerably reduce the transformer and motor sizes and weights hence improving the efficiency of the avionics and onboard systems. This creates the need for the aerospace 400 Hz power specialists and the certified 400 Hz suppliers who provide strong solutions based on the demand.
What types of 400Hz converters do suppliers offer?
Suppliers are likely to offer different frequency converters like, static frequency converters, rotary frequency converters, and portable 400 Hz converters for ground support and test benches. The majority of the vendors also provide customized 400Hz solutions and systems with power integration to cater for the specific needs of the aerospace and military industries.
Can 400Hz converters be used for civilian applications?
Indeed, the 400Hz converters are frequently seen in non-military applications like laboratories, simulators and peculiar industrial equipment since they have compact transformers and motors predominant. The vendors usually introduce the designs of military 400Hz converters to render certified and tailored 400Hz solutions to their industrial clients.
