Compact cabinet filter for quick installation and
easy commissioning
Cost-effective enclosed passive harmonic filter
Optimized for motor drives with DC-link
chokes
Helps to comply with international power
quality standards
Supports an efficient utilization of electrical
system capacity
Filters for diode rectifiers
Approvals
Typical application
Schaffner ECOsine filter cabinets can be applied to
virtually any kind of power electronics with front-end
six-pulse rectifiers, where harmonic current distortion
needs to be reduced to defined limits. The compact
filter cabinets can be easily commissioned and
quickly installed into extisting designs without
requiring an in-depth system analysis or highly
trained specialists.
Typical applications include higher power AC and DC
motor drives with either six diode used e.g. in HVAC,
water/wastewater, oil & gas, or mission critical factory
automation equipment. In addition, ECOsine filters
can help to reduce thermal and electrical overload
caused by harmonic currents in installations involving
UPS, high power rectifiers and other non-linear three-
phase power supplies.

Performance characteristics
THID – Total harmonic current
distortion
ECOsine high power passive harmonic filter
performance is optimized for rectifiers/motor drives
with a dc-link choke. In such applications, a THID of
roughly 5% can be expected. The use of a dc-link
choke is highly recommended. In a system without
L
dc
, the filter module has to be derated to max. 70% of
its nominal power rating. In such applications, a THID
of 10…15% can be expected.
Displacement power factor
At full load, ECOsine filters yield unity power factor.
At lower load levels, the capacitive current into the
power capacitors of the trap circuit cause a leading
displacement power factor. This is the case with all
types of passive filters with large capacitors. However,
compared to traditional filters the useful range of
Schaffner ECOsine is much extended (cos phi >0.9
from 35 to 100% of rated load).
ECOsine filters allow for trap disconnect at light load
to avoid low DPF situations if required. This feature
can be provided by the installer using a capacitor
contactor of suitable size for the trap circuit.
DC-link voltage
ECOsine harmonic filters have a very low impact on
the dc-link voltage of the motor drive. The voltage
variation as function of the load is represented in the
performance diagram beside. Tolerances are kept
narrow in order to ensure that motor drives do not
suffer from noise tripping because of under- or over-
voltage conditions.

Application
ECOsine filters are best installed directly at the input of 6-pulse rectifiers. It is possible to connect several non-linear loads (e.g. motor drives) in parallel. In this case the
rating of the filter must match the sum of the power ratings of loads connected to it.
