Modular harmonic filter launch

Jon Lawson

The Schaffner Group is introducing ecosine active sync series, its new generation of modular, compact active harmonic filters.

By deploying ecosine active sync filters it is possible to achieve a THID ≤ 5%. They also guarantee compliance with the toughest requirements of IEEE-519 and other stringent international power quality standards. 
Ecosine active sync filter systems can be easily installed as wall-mount devices based on 60A rms power modules. These modules are available in IP20 and IP21 protection class and in 3-phase 3-wire and 3-phase 4-wire configurations. Two power modules in a master/slave architecture can be configured as a dedicated solution for 120A rms. 

The Double Power Pack (DPP) offers real 120A rms without derating up to 50°C. For higher current ratings, up to 5 ecosine active sync power modules can be connected in parallel to mitigate harmonic current up to 300A rms. This can be done either as a wall-mount solution or within Schaffner’s new IP54 air-cooled cabinet. 
Ecosine active sync filters FN3430/31/32 are designed for 50Hz and 60Hz, 380VAC to 400VAC 3-phase 3-wire power grid, while the FN3440741/42 is designed for 50Hz and 60Hz, 380VAC to 415VAC 3-phase 4-wire grid.
