Power Filter Characteristics
UL listed filters will bare a UL listing label. The filter and filter elements comply with current revisions of MIL-F-15733,
UL-1283, and IEC 60939.
Insertion Loss (Stop Band)
100 dB from 14 kHz to 40 GHz tested no load per MIL-STD-220.
100 dB from 14 kHz to 20 MHz when tested full load per MIL-STD-220.
Power Factor Correction
If filter is to be used at 400 Hz, it is recommended that a Power Factor Correction coil is installed in shunt between
each phase voltage and ground in order to minimize the flow of reactive current. Once the power correction coil is
installed, the operating power frequency range of the filter then becomes 350 Hz to 450 Hz. For operation at other
frequencies or DC, the coils must be disconnected. Please call ETS-Lindgren before proceeding.
Current
As specified on filter label. Filter may be operated up to the filter’s rated maximum current. This is an RMS rating and
is a continuous 100% duty cycle rating. The filter may be operated on DC up to the same rating. If the filter is rated at
60 Hz, it may be operated at 400 Hz only if the current and voltage are de-rated to 50% of nominal 60 Hz operation.
Contact ETS-Lindgren for more information.
Frequency of Operation (Pass Band)
The filter is designed to operate in DC voltages up to the rated frequency operation indicated on the label. Typically
this will be 60 Hz or 400 Hz. The 400 Hz filters are indicated on the label having a “-4” suffix at the end of the model
number. See also POWER FACTOR CORRECTION paragraph above.
