Input
filters are available for DC input power supply Series B or S to
attentuate the AC ripple by a factor of 10. When the appropriate
filter is used with an Martek Power Abbott power module, electromagnetic
interference characteristics of the power module are also substantially
reduced. Conducted interference, conducted susceptibility, as well
as spike susceptibility levels are also reduced. Insertion loss
from the Martek Power Abbott filter has been held to a minimum
consistent with good attentuation. These hermetically sealed filters
have been designed to meet the rugged environments of MILSTD810C
and MILE5400P frequently encountered in aerospace and industrial
systems.

1. 
Attentuation
ratio as used here is a ratio or fraction whose numerator is the
AC voltage measured, RMS, across the input terminals of the power
module and whose denominator is the AC voltage measured. RMS,
across a onehalf OHM resistor connected in series with the plus
terminal of the DC voltage source, such as a battery. (The
onehalf OHM resistor synthetically represents the source impedance) 
2. 
Insertion
loss, as used here, is defined as the DC voltage across the input
terminals of the filter minus the DC voltage across the output
terminals of the filter. This may be as high as 0.9 volts
for models B10 and B17.
