| This
high quality 96x96 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

Four models available:
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.
