4.3. PRESENTATION.
EMi3 stabilizer model has been designed to operate in fluc-
tuated mains and to safeguard the critical loads, in particular,
those ones with a complicated nature: high inrush start up cur-
rents, high reactive character, high powers, etc. These equip-
ments are very robust against long overloads and they have
a high output accuracy (up to ±1%), they are manufactured
in single and three phase structures with independent phase
regulation or average regulation in the three phases depending
on the model.
Any three phase servomotor stabiliser has only one electronic
control card for all the phases and one LCD panel for its moni-
toring and complete control, less those ones that consist of
three independent single phase equipments duly connected to
make a three phase equipment. In these ones, each cabinet will
have its own electronic control card and its LCD panel.
Depending on the total power of the three phase equipments,
no matter if they include some options or not, they are supplied
assembled in one metallic cabinet, divided in two cabinets
joined together mechanically at factory or by three separate

cabinets, which will be joined after their final location.
The input and output are marked in the terminal strips of the
equipment. When installing the device, use the suitable cross
cable section in order to guarantee its correct operating.
The LCD of the control panel of the stabilizer allows checking
the input/output voltages and frequency, whenever you need.
Also, the LCD has measurements of output current, active and
apparent powers per phase and total, power factor per phase
and total and load percentage per phase. These last measure-
ments are only available when the equipment includes the cur-
rent transformers in each one of the output phases (option).
There are LED indicators to inform about both the status of the
equipment and the possible active alarms.
Single line diagram of a single phase equipment is shown in
Fig. 12 (the three phase structure is similar to it but repeating
the same block per each phase).
