MBS48 -SERIES
MBS4850
(DC line filter)
Features
1) High attenuation for any noise from low
frequency to high frequency
by applying large capacity condenser for DC 48V
power line
Major application: Information and
telecommunication equipment
2) Large stud teminal type
Several wiring connections available
3) Cost saving design
Compared with our current noise filter for the
same capacity for AC input,
Volume: Less than 30%
MBS4850S
Area occupation: Less than 45%
MBS4830
MBS48 series shall be noise
Specifications
CAUTION!
filters for DC 48V power line only.
Use for AC power line is not available.
