Static frequency converter SHT-FC 400 “brand SHANDY”
The static frequency converters for aerospace SHT-FC series are the result of a long experience both in UPS than in its converters. A complete range of products in the airport are available units in constant current regulators (CCR) for lighting systems and power supplies to 28Vdc.

These static frequency converters allow the use of the equipment also on airplanes, normally equipped with current to 400Hz in order to avoid disturbances in the air: thanks to a frequency converter is therefore possible to operate on planes normal devices when this is located at the airport.
The same static frequency converters are used in salt ground school, where they are taught the various tasks and techniques for use on airplanes, or to test equipment intended for use on aircraft.
