Static frequency converters, ELIT FC series, are outcome of a long experience both in UPS and in frequency converters field. To complete our apparatus series for airfield applications, constant current regulators for lighting system and 28.5vdc feeder for the engine starter are available. All of our equipments distinguish themselves by the employment of advanced technological components, excellent reliability and easy maintenance. The simplicity of working is the main feature of all of our products.
