ELIGHT constant current regulators
are expressly developed for the power supply of lamp series
circuits dedicated to public lighting systems, conforming
to the directives in force.
Constant Current Regulators, ELIGHT CCR series, are outcome
of a long experience static frequency converter both civil
and military field (receiving the NATO code for the quality
of his supplies).
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 ELIGHT CCR Constant Current Regulator has the purpose
to feed to series circuits a constant and sinusoidal current.
The rectifier transforms the input alternate voltage in direct
voltage, then the IGBT inverter transforms the dc voltage
in alternate and sinusoidal current with a PWM modulation
(Pulse Width Modulation).
With the ELIGHT CCR, keeping constant the current, the lamps
don’t feel the effect of reduction of the brightness
for getting old, neither for drop line voltage nor for cold
temperatures.
Features
- Input power factor at full load > 0.95;
- Efficiency > 90%;
- Energy saving with reduction of luminous flux;
- Reduced cable cross section of plant system (9.6A or 20A):
up to 100kVA;
- Absence of any stress on electrodes lamp during ignition;
- Certificated Insulation controller;
- 1% output current stabilization.
Equipment
description
The apparatus is composed by:
1. Input automatic circuit breaker with choke coil;
2. Rectifier;
3. PWM IGBT Inverter;
4. Transformer;
5. Control logic;
6. Parameter and control panel;
7. Continuity and insulation test;
8. Interface module (as option).
Monitoring control system (as
option)
ELITLUCE monitoring control system allows to monitor the status
and the working of street lighting series circuits.
Available functions:
- Display of voltage and current for each regulator: the voltage
value allows to know the fault presence;
- Start up and shut down of the regulators;
- Setting the function of the start up, the shutdown and the
working with reduced flux;
- Detection fault apparatus;
- Detection general alarms: steams, accesses, temperature;
- Power history: start up, shutdown, mains fault, flux reduced
periods, max temperature.
The network offers a simply way to connect the existing infrastructures
(meter sensor, control device for plant or other) allowing
to business government and companies to delegate management
and maintenance.
The net is Server-multi-Client and is based on TCP/IP protocol,
in order to obtain maximum flexibility and every kind of expansion.
The entire System has been developed with Java language, in
order to permit higher compatibility with every kind of apparatus
and any existing operative system.
Either Server or Client can be hosted on PC or MAC, with Windows
or Linux operative systems and with no use restriction.
Connectivity
ELITLUCE 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.
ELITLUCE 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.
