110VDC INVERTER MEDIUM AND  BIG SIZE



The ELIT inverter, INV 110 series, are outcome of a long experience both in UPS and in converters field. 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.
These apparatus are studied to be employed in:
- Automation
- Petrochemical and industrial plants
- Telecommunication
- Railway field
- Civil and military aviation
- Civil and military nautical

PRINCIPLES OF WORKING

The IGBT ELIT inverter, INV 110 series, transforms the continuous voltage into an alternating sinusoidal stabilized voltage. The PWM modulation technique used reduces the harmonic content of the output and limits voltage deviations under step load conditions.

FEATURES

The main components that composed the inverter ELIT INV 110 are:
• Input filter
• IGBT conversion unit (Inverter)
• Output filter
• Output insulation transformer
• Static switch as option
• Manual by-pass as option
• Insulation transformer for emergency line as option
• Parallel kit feature as option

INVERTER ELIT INV 110 COMPOSITION

a) IGBT Greatz bridge type with PWM regulation
b) Output current limitation
c) Output voltage detector min – max
d) Heat sink temperature detector
e) DC link voltage detector min - max
f) Short circuit running


STATIC BYPASS SWITCH (AS OPTION)
The bypass static commutator transfers the load from the inverter to mains upon failure or overload
The transfer occurs automatically without break.
Characteristics
a) Min – max mains voltage monitor
b) Quartz mains frequency monitor
c) Mains – inverter transfer manual or automatic and vice versa
d) Transfer inhibition mains – inverter after 5-6 attempts
e) Heat sink temperature detector

If any condition out of inverter characteristics occurs, the static bypass switches the load to the emergency line and the inverter is disconnected. When the normal conditions are restored, the inverter will be connected


CONTROL PANEL

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

INTERFACES

The apparatus are provided with a dry to remote the following signaling:
- inverter alarm
- inverter running
- ON/OFF remote control as option

Additional interface modules for measurements transmission as option:
- RS485 interface
- RS232interface
- Profibus interface
- Lonworks interface
- Output pulses
- Analogical output
- Alarms

MONITORING CONTROL SYSTEM
(as option)


The Monitoring Control System 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 pplication (telephone cable, ADSL/HDSL connections, optic fiber cable, GSM/GPRS modem, UMTS modem, HSPDA modem).

The System can use 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.
The Monitoring Control System has a Client platform, designed for mobile phones, with Java 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.
