STAR3

STAR 3

The latest instrument available from Elcontrol Energy Net.

This high quality 96*96 panel energy analyser provides brilliant features at a price
never reached before.

The new bright red LCD display, the harmonic analysis , the wide set of measured parameters including the THD available in all the models, the multi-protocol capability of the RS485 port and the high accuracy class 0.5%, the 3 years-warranty period, allow to consider the STAR3 the new state of art of the panel analysers market.

It is a perfect, professional and low cost solution for the electrical panels,
sub-metering systems, OEM applications, supervisory systems, Building and Factory automation systems.

The high flexibility of the instrument makes it adaptable to totally different applications.

The model with harmonics allows a permanent based control of one of the most important aspect of the power supply quality.
Such important possibility, up to now, was reserved only to high-cost device.
The STAR3 breaks this price barrier bringing, for the first time, the harmonic analysis into the market of the panel analysers

1) STAR3
Basic model. It shows all the measures listed in the above table. Includes an RS485 output with multi-protocol capability: Modbus RTU, Modbus IEEE and Modbus ASCII . The importance of the communication and the lower cost of the components allow today the inclusion of the RS485 port as a default features.
Even if you are not interested in making a network of instruments, this possibility will remains always available for future developments.

2) STAR3 ALM:
as the basic model+ two relay outputs. The outputs can be set be for either alarms signalling or pulses or remote relay control .
The function "alarm" can be associated with several measures including V,A,W,THD and harmonics. Each relay has a maximum and a minimum threshold, the histeresys and the delay time. All the settings can be adjusted.
If used in "pulse" mode the relays generate pulses proportional to the associated measures. Also in this case the behaviour is adjustable with the setup menu.
In "remote control" the position of the relay is decided by an external master device ( PLC, PC, etc) through the RS485 line . This is very convenient for load shedding application.

3) STAR3 4-20mA:
as the basic model + two analogue outputs 4-20 mA or 0-20 mA.

4) STAR3 HARMO:
as Star3 ALM+ three phase harmonics spectrum for voltage and current.
In addition to the basic measures of the above table, the harmonics model displays complete information about the spectrum.

For each harmonic order k the following values are available :

The accuracy of the harmonic measures is totally independent from the frequency of the fundamental.
The instrument measures harmonics up to the frequency 1250Hz which is the 25th in case of fundamental at 50Hz. In case of higher frequency value of the fundamental, the numbers of available orders decreases automatically.

OUTPUTS

1) RS485 :
serial communication output included in all models. It is now a standard feature
The STAR3 has an unique feature : allows the selection of t
hree protocols:
Modbus BCD (RTU)
Modbus IEEE
Modbus ASCII (only Vip Energy frame for compatibility with existing softwares)
The full control of the instrument is available only with the BCD and the IEEE format.
The ASCII format is limited to the same data frame of the VIP ENERGY; this allow the connection with all the existing softwares VIPLOAD, VIPVIEW, VIPVISION and the memory module VIPMEM

2) ALM
two digital outputs for alarms, pulses and remote control .
the alarms setup includes the association of the measures, thresholds,
hysteresys % and delay time.
The pulses setup includes association of the measures, number of pulses per unit , pulse width 100 msec or 20 msec

3) 4-20mA
two analogue outputs programmable in two different ranges: 4-20 or 0-20 mA.
The setup includes the association of the measures and the full scale value.

STANDARDS and REGULATIONS CE

The STAR3 conforms to directive IEC 1010-1 430 V for Cat. III and protection level 2 according to IEC 664-664 A. regarding the safety of the operators
It conforms to EN55011 ; EN61000-3-2 ; EN61000-3-3 ; EN61000-4-2 ; EN61000-4-3 ; EN61000-4-4 extension 4kV ; EN61000-4-5 ; EN61000-4-6 ; EN61000-4-8 ;
