Applications :

PROFI.PLUS-N  is the perfect solution for all kind of loads.
They stabilize the input voltage and improve the true power factor (by means of reducing losses of the loads caused of the incorrect value and shape of the voltage) while exclude the internal consumers distortions to return to the mains net.


PROFI.PLUS  systems consist of:

•    Lightning protection elements STRIKESORB-30.Surge Suppression Modules

Technical specifications : 60 kA (NEMA LS-1, Class II)

•    One PROFI.FLTER Passive input-output filter with zero time response which decrease up to 8 times the transients over voltage and over current as well as up to 50% of  the odd grade harmonics.
This filter protects from transients’ phenomena not only the consumers but also the whole unit

Voltage stabilizer made of

•    Three single phase voltage stabilizers with independent regulation. They are design to be connected to four wires net (three phases and neutral)  or after demand to three wires system(three phases).

Each stabilizer consist of
  • One motor controllable variable autotransformer which supplies the primary side of a
  • Buck-boost transformer, with the secondary side connected in series between the supply voltage and the load. This transformer adds or subtracts voltage from the mains to keep it between the permissible limits.
  • One electronic control board, supervising the input voltage and controlling the variable autotransformers motor which with its turn supplies the buck boost transformer and giving as a stabilized output voltage.

In addition

•    Economy mode
The unit through a switch stabilize the output voltage at  -10%, as a result we have
less energy consumption from the lights.
•    Artificial neutral
In the case of loosing the neutral from the net through an artifial neutral built in, the loads
will continue to supply with the nomimal voltage nad no overvoltage through earth will

•    Internal manual bypass.
•    Magnetothermic input circuit breaker
•    Thermal output fuses
•    Forced ventilation controlled by thermostat
•    Digital multimeter with indications of input voltage, output voltage, current, watts , kWh

The system is built into steel box painted with electrostatic paint color RAL 7032 protection
degree IP21, easily moved by wheels and secured at position with brakes.


As a conclusion the basic advantages of PROFI.PLUS systems are:

•    Complete lightning and transients’ protection.
•    Wide input voltage range. (± 20%).
•    High output voltage precision (±1, 5%).
•    Instant transient voltage correction.
•    Fast continuous phenomena correction.
•    Ability to withstand high starting currents (motors).
•    Absence of harmonic distortion.
•    Efficiency with full load: ~95%
