Static Frequency Converter 60-90kVA FC60

ELIT Srl designs and manufactures 60Hz static frequency converters since 1987.
All our equipment is distinguished by the use of technologically advanced components, for excellent reliability, and simple maintenance. The simplicity of operation is the main feature of all our equipment.


The apparatus converts the input mains voltage, at 50Hz, into an output voltage (galvanically isolated from the input) at 60Hz; the output voltage is stabilized in voltage and frequency and with low harmonic content in voltage.
The rectifier configuration depends on the harmonic current that the network (THDi) is able to withstand: for strong networks (> 10Pn) the THDi can be 25%, while for medium or weak networks the THDi must be 10% or up at 3%. The full load cosphì varies from 0.95 to 0.98 depending on the selected input magnetic configuration.
The PWM modulated IGBT inverter supplies the voltage adaptation transformer, its output is fitted with a filter to contain the distortion within 2%.

  • 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.
  • Automatic voltage compensation (DLC) optional.
  • Remote Point of Reaction (POR) (optional).
  • Interlock with bypass option (optional).
  • Remote control (optional).
  • Emergency Power Off.
  • UPS mode with battery (optional).
  • Multi voltage and multi frequency (optional).
  • Power history (optional).
  • RS485, RS232, SNMP and I / O communication interface (optional).

The converter is equipped with a backlit liquid crystal display, optional touch screen. The display is divided into four menus, accessible with the corresponding function keys.

The main measures are:
voltage (phase voltage, phase-to-neutral and neutral-ground), 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).
