YOUR VOLTAGE – OUR PASSION
The MιA® product family from Condensator Dominit GmbH is the lat-
est generation of active power filters with maximum performance at
minimal losses.
Power-regulated loads such as motors driven by frequency converters or ener-
gy-saving lamps are an essential component of our energy turnaround. At the
same time, these loads with a non-linear U-I characteristic curve provide for crit-
ical system perturbations due to harmonic currents.
Active filters are used to reduce harmonic currents, provide reactive power, min-
imize flicker and balance load currents. These measures are necessary wherever
networks do not conform to standards due to system perturbations.
EN 50160 describes the specified phenomena and defines the
permissible compatibility levels for public networks in low/medi-
um and high-voltage networks. The compatibility levels specified there
form the basis for the error-free and long-term operation of loads in
public networks. EN 61000-2-4 describes in parallel the compatibility levels
in industrial networks. In EMC class 2, this standard con-
forms to EN 50160. Thus, loads for public networks may
also be operated in Class 2 industrial networks.
If normative compatibility levels are exceeded, this can lead to downtimes in
production-relevant machines, systems and controls. If the compatibility level
is exceeded, suppliers are free from any guarantee, warranty or recourse claims.
MιA® implements the necessary standard conformity of your network and thus
prevents faults, failures or loss of warranty and guarantee claims.

MιA® NETWORK INTEGRATION
The network connection of MιA® takes
place parallel to the loads. Production pro-
cesses are not influenced by this during in-
stallation and maintenance work.
Through selection of the installation point
of the current transformers, there are many
possibilities to influence the active filter's
mode of operation. For example, indi-
vidual loads or entire network areas can
be filtered. Moreover, MιA® can be op-
erated in a closed-loop and open-loop
configuration.
In the closed loop configuration, the mea-
suring signal of the current transformer
is detected by the filter and load on the
grid side. If it is not possible for design
reasons to install the current transform-
ers on the grid side of the load and ac-
tive filter connection point, for example,
or if an extremely rapid sup-
ply of reactive current (har-
monics) is required, the open-loop
configuration offers an effective
and cost-efficient alternative.
CONSEQUENCESVoiding of warranty claims
Failure of control systems
Reduced service life of devices and systems
Increased noise emission from transformers and loads
Temperature increase at transmission devices such as transformers
Flickers
Increased CO2 emissions

MιA® detects the load current via the on-
site current transformers and calculates
the proportion of harmonic currents, reac-
tive power and load asymmetry (system
perturbation). A filter flow is fed into the
grid at the connection point via the intel-
ligent control structure. The filter current
now compensates for system perturba-
tions of the loads on the network side,
the voltage quality is improved, and rel-
evant standards (DIN EN 61000-2-4) can
be fulfilled.

THE MιA® PRODUCT FAMILY
The application-driven product selection
is intended to be facilitated by the various
designs. Two designs are available: the 400
V MιA®-WM wall-mount system with small
dimensions and the 400 V MιA®-S cabinet
design for higher capacities.
MιA® WM wall mounted systems can be
supplied with 20 A, 40 A, 100 A, 150 A, as
well as with and without a neutral con-
ductor connection. In the MιA®-S cabinet
design, up to 600 A rated current can be
realized. Here, as well, the user decides
whether filtering of the neutral conductor
is required.

All MιA® products feature the latest 3-lev-
el IGBT inverter technology, exhibiting
the highest ratings in power dissipation
and dielectric strength. The well-devised
modular and robust design of the MιA®
family is trend-setting and offers the user
a maximum of flexibility in expandability,
maintenance and repair. Should a power
module fail, the remaining modules can
continue working. Thanks to short deliv-
ery times in combination with the mod-
ular design, the defective module can be
easily replaced within a very short time.

Resonances are a comprehensive topic in
our constantly growing energy supply net-
works. Unchoked cable capacities or, for
example, EMC output filters, very frequent-
ly form unwanted but unavoidable network
resonances with inductive components
such as transformers or line inductances. In
order to effectively manage this sensitive
vulnerability of active filters, all MιA® are
equipped with Selective Resonance Moni-
toring (SRM). MιA® constantly detects and
monitors any resonance points in the net-
work and also reliably prevents resonance
excitation. That is why the operation of
active filters without selective resonance
monitoring is grossly negligent in light of
the dramatically changing load and net-
work structure.
� MASTERY OF SOPHISTICATED NETWORK SITUATIONS
Our key motivation for developing MιA®
was the continuous further development
of products towards increasing custom-
er satisfaction and to protect econom-
ic and ecological resources. MιA® sys-
tems superbly master this wide range of
tasks. For each product, the customer
decides which components are required.
For example, MιA®-WM and MιA®-S
can be selectively ordered with or with-
out an N conductor connection. The
systems continue to be available with
or without HMI. This display is espe-
cially suited for applications with many
filters at hard-to-reach installation loca-
tions. The parameterization can also be
performed without HMI via a Wi-Fi inter-
face, however.
The modular structure of the MιA® fam-
ily also makes it possible to adapt the
systems to a growing environment. For
example, MIA-S can be flexibly expanded
by adding power modules. This allows for
long-term, uncomplicated customer plan-
ning, without having to already specify
the final design during planning phase.
� ECONOMICAL USE OF RESOURCES
The 7-inch color touch panel in the wall
housing or control cabinet ensures us-
er-friendly and organized operation of the
system. Naturally, comprehensive test
functions and a commissioning assis-
tant are available for commissioning.
The display interface is equipped with
many languages, thus facilitating its use
in worldwide applications. The intuitive
operation via the display, the straightfor-
ward structure of the software and the
well-organized layout make it easier for
the user to obtain the desired information
quickly and easily.

The availability of electrical energy is a deci-
sive factor for safe and reliable production.
Any quality sacrifices in voltage quality en-
dangers the energy supply, the operational
safety of plant components, control tech-
nology and IT systems. The key causes of
poor voltage quality are frequency convert-
ers, power converters, UPS systems, PCs,
welding machines and many more. They
generate undesired system perturbations,
which are characterized by a high harmonic
content.
The problems caused are myriad:
u Relevant standards of the
voltage quality are violated
u Guarantee and warranty
claims towards the manufacturer
are voided
u In cables, distributions, trans-
formers cause harmonics
additional thermal losses.
u The service life of motors is
reduced through counter or pendulum
torques.
u Malfunctions and failures of
loads
