STATIC FREQUENCY CONVERTERS 60 Hz

Static frequency converters, ELIT FC series, are outcome of a long experience both in UPS and in frequency converters field. The frequency converter FC60 is particularly suitable where the highest product reliability and availability is demanded
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 frequency converter, making it particularly suitable for the power of all equipment requiring different power supply frequency. Normally this device can in fact receive 50Hz frequency input and supply 60Hz in output, and vice versa.

For his high lean to be customized, the frequency converter FC60 is usually employed in several applications as industrial and testing process, naval, and petrochemical plant. 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 an 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.

CONTROL PANEL

The control panel is divided in three parts:
- LCD display (PMD);
- LED indicators
- Keyboard.

LCD display
The LCD display meter provide to give the following output data:
- Voltage;
- Current
- Frequency;
On request and conforming to technical data of the apparatus the LCD can have the following characteristics:
LCD backlit. Display is subdivided into four menus which are accessible by pressing the relevant function keys:
- Voltage phase voltage, active Energy, linked voltage, reactive voltage phase voltage min. value and max value, harmonic distortion phase voltage;
- Current phase current, active energy, phase current demand, reactive energy, phase current max demand, neutral current, harmonic distortion phase current;
- Power Active, reactive, apparent power, phase active power, reactive energy, phase reactive power, phase apparent power, active, reactive apparent power demand and max demand;
- Power factor;
- Frequency ;
- Working hours and minutes;
- Positive and negative active Energy;
- Positive and negative reactive Energy.

LED signaling
- Mains;
- frequency converter running;
- frequency converter alarm.

Keyboard
Possibility to select the desired menu, to load a customized display page and modify the programmable parameters.

INTERFACES

The apparatus are provided with a dry contact to remote the following signaling:
- frequency converter alarm;
- frequency converter running;
- ON/OFF remote control.

Optional modules:
- RS485 communication;
- RS232 communication;
- Profibus communication;
- Lonworks communication;
- Pulse output;
- Analog output;
- Alarms;
- Neutral current.

MONITORING CONTROL SYSTEM (as option)

ELIT FC60 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.

ELIT FC60 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.

CUSTOM VERSION

We realize custom apparatus according to customer's technical data employing the standard series sets and therefore with experimented feature.
