STATIC FREQUENCY CONVERTERS 400Hz
5 ÷ 45kVA FC400
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.
PRINCIPLES OF WORKING
The benefit of a 400Hz electric system resides in lowered dimensions and weight respect an analogous system to 50Hz or 60Hz.
|
Benefits, these ones, very important on board of an aircraft where the space is always narrowed and it is a must minimize the weights and maximize the performances.
The FC400 static frequency converter allows to feed the aircraft on runway transforming the 50/60Hz mains voltage into a sinusoidal, stabilized and galvanic insulated 400Hz voltage.
The employ of the converter allows the electric system test, keeping OFF the aircraft's engines.
A diode rectifier transforms the AC voltage into a continuous stabilized DC link voltage, to power the IGBT inverter that transforms the continuous voltage into a 400Hz alternating sinusoidal stabilized voltage with a PWM modulation. The output inverter voltage feeds a transformer which on its output have the filter capacitors.
The output voltage is sinusoidal with a distortion of 3%. The output has an electronic stabilization both in voltage and in frequency.

MONITORING CONTROL SYSTEM (as option)
ELITAVIO manages communication from and to remote devices, distributed in two ways:
. Physical connections;
. Wireless connections.
These two kinds of connections can be combined at any way, to use in the better way the available
infrastructures for the application (telephone cable, ADSL/HDSL connections, optic fiber cable, GSM/GPRS modem, UMTS modem, HSPDA modem).
The System can use two dedicated lines by cable, optic fiber or it can use a point of access through LAN network
or internet in remote plant allowing the management with automatic calling or through request of the control device.
The Workstation logs on Central System through LAN or Internet network allowing the complete compatibility of the System.
ELITAVIO has a Client platform, designed for mobile phones, with Java ELITMobile platform. It allows to access directly with
the phone to all data of the Server and to perform all maintenance actions in remote.
The Central System controls every access with login procedure, classifying them in different levels according the
operative level that you desire to give at each user.
