Active sync harmonic filters are modular

Compact active harmonic filters from Schaffner, the FN 3530, FN 3531, FN 3540, FN 3541, FN 3532, FN 3542 and FN 3545 are claimed to offer the most effective harmonic mitigation solution available, especially for mixed load and dynamic load profiles.

By deploying ecosine active sync filters it is possible to achieve a THID up to or equal to five per cent. They also guarantee compliance with the toughest requirements of IEEE-519 and other stringent international power quality standards.

The filters operate over an extended temperature range (power module 0 to 50 degree C full performance, up to 55 degree C with derating). With the installation of the ecosine active sync filters, harmonic current mitigation, reactive power compensation as well as load balancing can be efficiently achieved and international power quality standards complied with, says Schaffner.

The modular concept ecosine active sync filters enables tailored solutions. Ecosine active sync filter systems can be easily installed as wall-mount devices based on 60A rms power modules. The modules are available in IP 20 and IP 21 protection class and in three-phase three-wire and three-phase four-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 degree C, says Schaffner.

For higher current ratings, up to five 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 IP 54 air-cooled cabinet.

Ecosine active sync filters FN 3530, FN 3531 and FN 3532 are designed for 50 and 60Hz, 380 to 480V AC three-phase three-wire power grid, while the FN 3540, FN 3541 and FN 3542 are designed for 50 and 60Hz, 380 to 415V AC three-phase four-wire grid. Power modules and DPP are available as protection category IP 20 (IP 21 as an option), while cabinet versions are of IP 54. All filters are CE-marked and RoHS compliant. Ecosine active sync filters are simple to install and maintain and are fully integrated in Schaffner’s popular and simple to use online power quality simulator the SchaffnerPQS3.
