Datasheet

The NFO Sinus® frequency inverter is based on a patented Swedish
technology that allows you to control the speed of electric motors
without generating electromagnetic interference, which in turn
offers a range of unique benets. Thanks to the sine-wave voltage,
the inverter is intrinsic EMC, i.e., it is interference-free in itself.
Simple installation

NFO Sinus® is available in size 0,37 kW up to 22 kW
SIMPLE
Installation is easy and cost-efcient due to there is no
need of shielded cables, EMC lters or other EMC-classed
installation accessories. When undertaking energy efciency
projects, it’s also possible to use the existing none shielded
cables, this makes the installation work quick, easy and
cost-efcient. There is no cable length limitation between
the motor and the NFO Sinus® except for the resistance
of the cable. The NFO Sinus® can be installed where it’s
suitable depending on the application, even if the distan-
ce to the motor is several hundred meters thanks to the
Sinus technique which gives cost-efcient exible solutions
in all environments.
SILENT
NFO Sinus® is interference free and therefore does not
create any electromagnetic interference which can distur-
bed surrounding equipment. The NFO Sinus® satises
the most stringent demands set out in the EMC directive
2014/30/EU without lters and without shielded cables
and can be used in every kind of environment from
industrial, medical to residential. With NFO Sinus® you
also avoid all the disturbing switching noise in the motor,
which results in a quieter environment.
SAFE
NFO Sinus® does not generate any bearing currents. The
motor therefore has a longer lifespan. No earth leakage
currents are generated, which means that residual current
devices for both personal safety and re prevention can be
used. This provides a high level of electrical safety.
HIGH PRECISION
The motor speed is very precisely controlled and with
full torque right from stand-still as well as at a low speed
regardless of chosen control mode Speed, frequency,
torque or process-control . The inverter furthermore has
an energy-save function that allows you to conserve even
more energy when running with a low load on the motor,
e.g., fans, which at times run at a low speed.
