ELIT Srl designs and manufactures 400Hz & 28Vdc static frequency converters since 1987. To complete the airfield range of products are available 270Vdc ground power units, constant current regulating units (CCR) for ground lighting and control systems for commercial and military airports. All the equipment is distinguished by the use of technologically advanced components, reliability, and ease of maintenance.
Ground Bipower FC400 + SE 28
Description
The bipower FC400 + SE 28 GPU can simultaneously power users by converting the input network voltage to 50 / 60Hz, in an output voltage of 400Hz and 28Vdc; the two outputs are galvanically isolated, completely independent in regulation and operation and can work simultaneously. The output voltage at 400Hz is stabilized in voltage, quartzed in frequency and with low harmonic content in tension. The DC voltage
output at 28VDC is stabilized, with ripple voltage of less than 1%.
- Galvanic input / output isolation.
- Three-phase input voltage without neutral.
- High performance.
- High overload capacity.
- Analyzer with 128×112 pixel graphic LCD, touch-screen, harmonic analysis.
- Emergency Power Off.
As an option
- Two independent and automatic Voltage Compensations (DLC) 400Hz and 28Vdc.
- Two remote Point of Reaction (POR) at 400Hz and 28Vdc independent.
- Two interlocks with the possibility of independent EF bypasses at 400Hz and 28Vcc.
- Remote control.
- UPS mode with battery.
- Power history.
- RS485, RS232, SNMP and I / O communication interface.
The converter is equipped with a backlit liquid crystal display, optional touch screen for 400Hz output and an LCD panel for 28Vdc output. The display is divided into four menus, accessible with the corresponding function keys.
The main measures at 400Hz are:
voltage (phase voltage, phase-to-neutral and neutralground), main voltage (only for DC power supply), phase current, neutral current calculated and real power (active, reactive and apparent phase and total) P.F. (Power factor of each phase and total), Cosphì of each phase and total frequency (frequency measurement of the voltage measured), asymmetry of voltage and current, total harmonic distortion (THD) of voltages and currents, analysis of voltage and current up to the 63rd harmonic function max. (HIGH) and the min. (LOW) for the acquisition and storage of the instantaneous values of voltage, current, power, PF, Con. and frequency averaging function peak values (maximum demand) power and current flow direction of the power harmonics energy meters for active, reactive, apparent (partial and total functions with programmable tariff) counter (total and partial programmable) texts in 5 languages (Italian, English, French, Spanish and Portuguese).
Accuracy for IEC / EN 50470-3 (MID Class B).
The main measures at 28Vcc are:
– output voltage
– output current
Signaling:
– mains presence
– converter running
– alarm.
