Schaffner Ecosine ® Economy Line FS 42842 Compact Passive Harmonic Filter

Product basic information

Product positioning: Schaffner’s economical passive harmonic filter, belonging to Ecosine ®  The product series focuses on compact design and is suitable for scenarios where harmonic suppression requirements do not exceed 10% THDi (with Ldc), which is different from the Ecosine Evo series (FN 3440/50) that provides high-performance THDi<5%.

Core values:

Compliance: Meets power quality standards such as EN 61000-3-12 and IEEE-519 (Isc/IL<50).

System optimization: Reduce overload and heating caused by grid harmonics, improve power system capacity utilization, reduce system resonance risk and the probability of sensitive electronic equipment shutdown.

Convenient upgrade: Quickly upgrade standard motor drivers to “low harmonic drivers”.

Core technical parameters

Flame retardant rating: UL 94 V-2 and above, reducing the risk of fire.

Mean Time Between Failures (MTBF):>200000 hours (45 ° C/500V, according to Mil-HB-217F standard).

Key points for installation and selection

Installation requirements

Installation position: Directly installed at the input end of the 6-pulse rectifier to suppress harmonics nearby.

Multi load parallel connection: It can connect multiple nonlinear loads (such as multiple motor drivers), and the rated power of the filter needs to match the sum of all load powers.

High power adaptation: When a single filter has insufficient power, multiple filters of the same power model can be connected in parallel to ensure equal current distribution.

Accessory requirements: External UL certified fuses are required (specific model not specified in the document, optional).

Selection principle: Select based on system voltage and load (motor driver) power, and it is not recommended to select based on current rating like EMC/EMI filters.
