MMM-3007-DSL - Terasic Technologies

Features and benefits

Broad range of power ratings for fast

and convenient filter selection.

Available as 440VAC (FN 351) and

520VAC (FN 351H) versions for network-

specific applications.

FN 351 filters provide a broadband

common and differential-mode

attenuation performance, which

remains available also when high

interference levels are present.

Solid, touch-safe filter terminals

contribute to overall equipment safety

and make the filters compliant with IEC

60950.

Introduced as one of the very first

motor drive EMC filters in the market,

FN 351 has been widely imitated and

has success- fully proven its function

over more than 10 years.

Typical applications

Three-phase motor drives

Inverters and converters

Industrial automation equipment

UPS

SMPS

General purpose three-phase filtering

** Calc ulated at rated current, 400VAC (FN 351)/480VAC (FN 351H) and c os phi = 0.8. The exact value depends upon the effic iency of the drive, the motor and the entire

application.

*** Maximum leakage under normal operating conditions (FN 351 at 400V, FN 351H at 480V). Note: if two phases are interrupted, worst case leakage c ould reach 6 times

higher levels.
